Key Takeaways

  • LY Corporation is the merger of Yahoo Japan and LINE as of October 1, 2023, headquartered in Kioicho, Tokyo, with roughly 28,000 employees under co-CEOs Takeshi Idezawa and Kentaro Kawabe.
  • Every mid-career application flows through HRMOS at hrmos.co/pages/lycorp/jobs/{id}/apply after acknowledging a role-specific privacy notice on lycorp.co.jp.
  • Two documents are expected in Japanese-style applications — a resume (rirekisho) and a work history (shokumu-keirekisho) — and HRMOS gives you two upload slots for exactly this reason.
  • Engineering hiring is meaningfully international and English-friendly; Product Planner, data, and designer tracks are similarly accessible; sales, legal, HR, and corporate tracks require Japanese at JLPT N2 or higher.
  • Interviews are three to four rounds with a HackerRank coding test for engineers, and compensation is at the top of the Japanese tech market with genuine room to negotiate for senior roles.
  • The 2024 LINE data breach, the two rounds of MIC administrative guidance, and the ongoing Korea-Japan capital conversation with NAVER are real context; interviewers appreciate candidates who engage with it honestly rather than ignoring it.

About LY Corporation (LINE/Yahoo)

LY Corporation is the largest internet company in Japan and the product of one of the most consequential mergers in Asian tech: on October 1, 2023, Z Holdings completed the statutory merger of its two flagship subsidiaries — Yahoo Japan Corporation (the country's dominant portal, mail, news, auctions, shopping, and weather property since 1996) and LINE Corporation (the messaging platform with roughly 95 million monthly active users in Japan, functionally the national utility for chat, stickers, news, and payments). The combined entity was renamed LY Corporation and is headquartered at Kioi Tower in Kioicho, Chiyoda-ku, Tokyo, with additional offices in Fukuoka, Osaka, Kyoto, Naha, and development centers in Seoul, Taipei, Hanoi, Jakarta, and Bangkok inherited from the old LINE footprint. The company employs roughly 28,000 people across the group and is led by co-Representative Directors Takeshi Idezawa (the former LINE CEO) and Kentaro Kawabe (the former Yahoo Japan and Z Holdings CEO), with SoftBank Group and Korea's NAVER Corporation sharing ultimate ownership through A Holdings, the joint venture that sits above LY in the corporate chart. The product portfolio is vast and genuinely woven into Japanese daily life: LINE messenger and its ecosystem of stickers, LINE News, LINE Manga, LINE Music, LINE Games, and LINE VOOM; Yahoo! JAPAN portal, Yahoo! Mail, Yahoo! News, Yahoo! Auctions, Yahoo! Shopping, Yahoo! Finance, and Yahoo! Weather; LINE Pay and the 50%-owned PayPay mobile wallet joint venture with SoftBank that now dominates Japanese QR code payments; ASKUL e-commerce logistics; and ZOZO fashion retail. The working culture is unusually international for a Japanese listed company — LINE was founded inside NHN Japan by a Korean parent and has always been bilingual, and the merged entity continues to hire engineers and designers from across Korea, Taiwan, China, Vietnam, and Indonesia while publishing its recruiting site in English as well as Japanese. Technology stacks lean heavily into the JVM (Kotlin, Java, Scala), Python for data and ML, Go and Rust for infrastructure, Swift and Kotlin for mobile, and React and TypeScript on the front end, running on a mixture of private data centers and public cloud. It is important to be candid about the headwinds, because they shape hiring: in late 2023 and throughout 2024, LINE Yahoo disclosed a significant data breach traced to a shared authentication system with NAVER Cloud, affecting hundreds of thousands of accounts and triggering two rounds of administrative guidance from Japan's Ministry of Internal Affairs and Communications that explicitly requested the company reduce operational and capital dependence on NAVER. The resulting diplomatic strain between Seoul and Tokyo, combined with reports that NAVER was exploring selling part of its stake in A Holdings, has produced a period of visible security hardening, vendor separation, and organizational restructuring. Candidates should expect questions about information security and should not be surprised that some Korea-based development functions are being repatriated to Japan. For those willing to engage with a company that is simultaneously rebuilding its security posture, consolidating two enormous engineering organizations, and running the services millions of people open the moment they wake up, LY Corporation offers the rare combination of consumer-scale problems, deep pockets, and an operating environment that is more English-friendly than almost any other large Japanese employer.

Application Process

  1. 1
    Identify the right track

    Identify the right track. LY Corporation separates hiring into two distinct portals: New Graduate Recruiting (shinsotsu) at lycorp.co.jp/en/recruit/newgrads/ for students graduating within the next cycle, and Mid-Career Recruiting (chuto) at lycorp.co.jp/en/recruit/career/ for experienced professionals. The two processes use different forms, timelines, and in many cases different interviewing panels, so applying through the wrong track is a common way to get rejected without review.

  2. 2
    Browse openings in English or Japanese

    Browse openings in English or Japanese. The Search Job Openings page at lycorp.co.jp/en/recruit/career/job-categories/ lists current mid-career roles filtered by function — Engineering, Designer, Sales, Planning, Data Analyst, and Corporate. Each role has a unique internal ID of the form ly#####, which is preserved all the way through the application system and is worth noting because recruiters reference it in follow-up email.

  3. 3
    Read the role detail page carefully

    Read the role detail page carefully. LY publishes unusually long job descriptions for Japan, covering team mission, technical stack, product context, required experience, and welcome experience in separate sections. The distinction between must-have and nice-to-have is real — Japanese-style listings historically treat everything as required, but LY follows the LINE convention of genuinely differentiating, and candidates who meet the must-have list but lack the welcome items are routinely shortlisted.

  4. 4
    Click Apply and acknowledge the privacy policy

    Click Apply and acknowledge the privacy policy. Every mid-career job routes the Apply button through a role-specific privacy notice at lycorp.co.jp/en/recruit/career/privacy-policy/{id}/, which you must accept before proceeding. This is not a dark pattern; it is a legal requirement under Japan's Act on the Protection of Personal Information and a reaction to the 2024 data incident, and the notice describes exactly what data will be transferred to the ATS and how long it is retained.

  5. 5
    Land in HRMOS and create an account

    Land in HRMOS and create an account. After accepting the privacy notice, you are redirected to hrmos.co/pages/lycorp/jobs/{id}/apply, which is LY's HRMOS instance — a Japanese applicant tracking system made by BizReach. First-time applicants create an HRMOS candidate account with email and password; returning applicants reuse the same account across every LY role, so your profile, resume, and past application history persist between attempts.

  6. 6
    Complete the HRMOS profile and upload documents

    Complete the HRMOS profile and upload documents. LY expects two files, not one: a resume (rirekisho) covering education and employment history, and a separate work history document (shokumu-keirekisho) covering detailed project-by-project accomplishments. English-only PDFs are accepted for most engineering, data, and product roles; Japanese is strongly preferred for sales, legal, HR, and finance tracks. Ensure Japanese characters render correctly by embedding fonts in the PDF.

  7. 7
    Submit and wait for the document screen

    Submit and wait for the document screen. Screening is handled by an internal sourcing team that reviews submissions within roughly one to three weeks, depending on role volume. If you pass, a recruiter sends an HRMOS-generated email with interview scheduling links; if you are declined, the rejection arrives through the same channel. Silence beyond three weeks is a soft signal to email the role-specific contact listed on the privacy notice.

  8. 8
    Interview in multiple rounds

    Interview in multiple rounds. The typical mid-career loop is a recruiter phone screen, one or two technical or functional interviews with the hiring team and a senior engineer or senior peer, a hiring manager interview focused on scope and ownership, and a final interview with a department head or VP. Engineering candidates additionally complete a HackerRank coding test, usually delivered as a take-home with a firm deadline between the recruiter screen and the first technical interview.

  9. 9
    Receive an offer and negotiate

    Receive an offer and negotiate. LY issues offers as a Japanese naitei (informal offer of employment) followed by a formal written contract. Salary bands are known in the market to be meaningfully above the typical Japanese tech mean — LINE historically paid at the top of the Tokyo technology market — and there is genuine room to negotiate base, sign-on bonus, and start date, particularly for senior engineering and data roles where competition with foreign firms is real.

Resume Tips for LY Corporation (LINE/Yahoo)

recommended

Write two documents for Japan, not one

Write two documents for Japan, not one. Even if you apply in English, mirror the Japanese convention of separating a chronological resume (education, employment, certifications) from a work history document that goes deep on each project: business context, your role, the team size, the technology, the measurable outcome. HRMOS lets you upload both, and hiring managers expect both.

recommended

Lead with scale and reliability, because that is the LY story

Lead with scale and reliability, because that is the LY story. Every product in the portfolio operates at tens or hundreds of millions of users; quantified throughput, latency, uptime, QPS, and cost-per-request numbers from previous roles are read carefully. Vague claims of improved performance are discounted. Specific numbers like reduced p99 latency from 280 ms to 95 ms at 40 k QPS are read twice.

recommended

Match the stated stack when it truly matches your experience

Match the stated stack when it truly matches your experience. Engineering roles at LY are typically Kotlin or Java on the JVM with Spring or Armeria, Scala for data and streaming with Kafka and Flink, Python for machine learning and data science, Go for infrastructure, and Swift and Kotlin for native mobile. Front-end roles are React and TypeScript with Next.js appearing in newer products. Name the exact frameworks from the job description that you have actually used.

recommended

Address the information security theme directly if you have relevant experience

Address the information security theme directly if you have relevant experience. Post-2024, LY hiring panels are especially attentive to security engineering, identity and access, zero trust, key management, and data governance. A line on your resume about driving SOC 2, ISO 27001, or zero-trust architecture work will be noticed far more than it would have been before the breach.

recommended

Call out bilingual or multilingual capability

Call out bilingual or multilingual capability. LY is one of the few large Japanese employers where English is a legitimate working language for entire engineering organizations, and teams are genuinely Korean-Japanese-Taiwanese-Vietnamese-Thai. Explicitly list your Japanese level (JLPT N1, N2, N3, conversational, or none) and any Korean, Chinese, or Southeast Asian language capability.

recommended

Demonstrate product thinking for planner and PdM roles

Demonstrate product thinking for planner and PdM roles. Product Planner candidates should describe problems, hypotheses, experiments, and outcomes rather than feature launches. Include A/B test results with effect sizes and confidence intervals where possible; LINE and Yahoo Japan are both heavy A/B testing cultures and will expect this vocabulary.

recommended

Show community contribution for senior engineers

Show community contribution for senior engineers. LY has a visible open source and technical community presence through LINE Engineering blog, LY Corporation Tech Blog, and conference talks at builderscon, YAPC Japan, KubeCon, and JVMLS. Published talks, OSS commits to projects your team depended on, and technical writing differentiate senior candidates.

recommended

Keep the layout ATS-friendly

Keep the layout ATS-friendly. HRMOS accepts PDF and Word but parses PDF most reliably. Use a single column, no text inside images, standard headings, and either Noto Sans or Yu Gothic if any Japanese text appears. Avoid tables for layout and avoid headers and footers that encode critical data, because parsers routinely drop those regions.

recommended

Tie your experience to an LY service whenever possible

Tie your experience to an LY service whenever possible. Candidates who explicitly reference which product their skills would apply to — LINE Messaging, PayPay, LINE Pay, Yahoo Auctions, Yahoo Shopping, LINE Manga — signal that they have done the homework and have a thesis about where they fit, which moves interviews from abstract to concrete.

ATS System: HRMOS (by BizReach)

LY Corporation routes every mid-career application through HRMOS, the applicant tracking system made by BizReach, at hrmos.co/pages/lycorp/jobs/{role_id}/apply. HRMOS is one of the two or three dominant ATS platforms in Japan and is used by a large slice of the Japanese technology sector including Mercari, SmartNews, and Rakuten business units. The system presents a candidate-facing account that persists across every LY role you ever apply to — one login, one profile, one document library — and a recruiter-facing kanban pipeline that feeds LY's internal hiring dashboard. Parsing is Japanese-aware and handles both English and Japanese PDFs, though Japanese fonts must be embedded to render correctly in recruiter previews. Job-level apply links are role-scoped, so bookmarked URLs from six months ago may 404 once a requisition is closed.

  • Apply in the language of your resume — HRMOS accepts English PDFs for international engineering and data tracks, Japanese PDFs for local and corporate tracks, and will not penalize English submissions for international roles.
  • Upload both a resume and a work history document when the system offers two file slots; leaving the second slot empty is read as an incomplete application.
  • Fill in every structured field in the HRMOS profile — current employer, years of experience, desired compensation — because recruiters filter on these fields before opening the PDFs.
  • Reuse your HRMOS account across applications rather than creating duplicates; duplicates confuse sourcing and can mark you as inactive on the earlier profile.
  • Embed Japanese fonts (Noto Sans CJK JP or Yu Gothic) in any PDF that contains Japanese text, because HRMOS previews render in a font-limited environment.
  • Save your HRMOS password securely, because the same account will be used across every future LY role and across any other HRMOS-based employer you apply to later.

Interview Culture

LY Corporation interviews are noticeably more direct and more English-friendly than the Japanese corporate average, reflecting the LINE cultural lineage and the international composition of engineering teams. A standard mid-career loop for an engineering role runs three to four rounds over three to five weeks: a thirty-minute recruiter screen to confirm motivation, visa status, language ability, and compensation expectations; a HackerRank take-home coding test with a firm deadline, typically two or three medium-difficulty algorithmic problems; one or two technical interviews with the hiring team that combine a live coding or system design exercise with questions about past projects, failure modes, and architectural judgment; a hiring manager interview focused on scope, ownership, and collaboration with cross-functional peers; and a final interview with a department head, VP, or in some cases one of the co-CEOs' direct reports. Product Planner, designer, and data analyst loops substitute the coding test for a portfolio review or a written case study, and finance, legal, and HR loops are conducted primarily in Japanese. Interviewers evaluate against a stated set of LY values that includes WOW (user delight), Immerse Yourself (genuine product love), Trust and Respect (with peers from different cultures), and Be Open (about mistakes and risks), and strong candidates visibly map their stories to these values without reading from a script. Expect at least one question that probes your reaction to the 2024 data incident or more generally your security instincts — you do not need inside information about the breach, but an honest answer about how you think about data minimization, secret handling, and incident response earns credit. English is accepted throughout engineering and most product interviews, and Japanese is welcomed but not required for those tracks; for sales, corporate, and legal, Japanese at JLPT N2 or above is effectively mandatory. Candidates coming from non-Japanese tech backgrounds often find the pace of decision-making slower than at American big tech and the feedback cycle longer, but the technical bar on coding and design interviews is comparable to Google, Meta, or a senior Mercari loop. The interview is a genuine two-way conversation — questions about roadmap, headcount, on-call load, Korea-Japan team structure post-breach, and promotion velocity are read as signs of seriousness, not as pushback.

What LY Corporation (LINE/Yahoo) Looks For

  • Scale instinct — the ability to reason about systems that serve tens of millions of daily active users without blinking, and the habit of quantifying work in QPS, p99 latency, uptime, and cost rather than feature counts.
  • Bilingual or multilingual operating capacity — you do not need to be fluent in Japanese for most engineering and data tracks, but comfort collaborating across Japan, Korea, Taiwan, and Southeast Asia in English is a hard requirement.
  • Product empathy for daily-life software — LINE, Yahoo Japan, PayPay, and LINE Pay are utilities, not novelties, and LY hires people who feel personally responsible when a service breaks for an elderly user or a merchant.
  • Security-minded engineering — post-2024, the bar on identity, authentication, secrets management, and least-privilege thinking has risen visibly, and candidates who demonstrate this mindset without being prompted stand out.
  • Humility across cultures — Trust and Respect is a stated value with real operational meaning given the Korean, Japanese, Taiwanese, and Vietnamese composition of engineering; candidates who treat disagreement as ordinary and depersonalized are valued.
  • Technical specificity — vague claims about driving transformation are discounted; concrete descriptions of what broke, what you did, and what the measurable outcome was are what recruiters and interviewers quote back to each other.
  • Open-source and community presence for senior levels — conference talks, blog posts, and upstream patches to the infrastructure your team depends on differentiate staff and principal candidates in a crowded Tokyo market.
  • Comfort with ambiguity about the future — LY is mid-integration across Yahoo Japan and LINE back ends, mid-remediation on security, and mid-negotiation on the Korea-Japan ownership question, and the best candidates treat that as interesting rather than a red flag.

Frequently Asked Questions

What ATS does LY Corporation use for applications?
LY Corporation uses HRMOS, the Japanese applicant tracking system made by BizReach. Every mid-career role redirects from lycorp.co.jp/en/recruit/career/job-categories/{id}/ through a privacy acknowledgment page to hrmos.co/pages/lycorp/jobs/{id}/apply. Your HRMOS account persists across every LY role and across any other HRMOS-based Japanese employer, so save the login.
Do I need to speak Japanese to work at LY Corporation?
It depends on the role. Engineering, data science, machine learning, and many designer and product planner roles operate in English as a first-class working language, a cultural legacy from LINE's bilingual origin. Sales, legal, HR, finance, and most corporate roles require business-level Japanese, typically JLPT N2 or above. The job description states language requirements explicitly; trust what it says.
How many rounds are in a typical LY Corporation interview loop?
Most mid-career loops are three to four rounds over three to five weeks. The structure is a recruiter screen, one or two technical or functional interviews (engineers also complete a HackerRank take-home), a hiring manager interview, and a final interview with a department head or VP. Executive-level hires add one or two rounds.
Is LY Corporation part of SoftBank or NAVER?
Both, through a joint venture. A Holdings, jointly owned by SoftBank Group and NAVER Corporation, sits above LY Corporation in the corporate structure. The 2024 Japanese government administrative guidance to reduce operational and capital dependence on NAVER, combined with reporting that NAVER has explored partial divestiture, means the ownership balance is under active conversation and may shift during your tenure.
Should I worry about the 2024 data leak affecting hiring?
The opposite — security-conscious engineers, identity and access specialists, privacy engineers, and compliance professionals are being hired more aggressively than before. Interviewers ask about security instincts in many loops, and candid answers about data minimization, secret handling, and incident response are welcomed. Avoid speculating about the breach itself, since you do not have inside information, but engage with the topic when it comes up.
What is LY Corporation's typical compensation structure?
LY pays at the top of the Japanese technology market, continuing the LINE tradition. Mid-career engineering packages are typically a base salary in Japanese yen plus a performance bonus and sign-on bonus where applicable; executive and senior engineering tracks include restricted stock units. Compensation is genuinely negotiable for experienced hires, especially in engineering, data, and security tracks where competition with foreign firms is real.
What are the main technology stacks used at LY Corporation?
Engineering at LY runs on Kotlin and Java on the JVM with Spring and Armeria frameworks, Scala for data and streaming with Kafka and Flink, Python for machine learning and data science, Go and some Rust for infrastructure, Swift and Kotlin for native mobile, and React with TypeScript and increasingly Next.js on the front end. Data platforms use Hadoop, Spark, and internal systems, and the company runs a mixture of private data centers and public cloud.
Does LY Corporation sponsor work visas for foreign engineers?
Yes, routinely. LY is one of the largest foreign-engineer employers in Japan and operates a Highly Skilled Professional visa and Engineer visa sponsorship pipeline through its HR operations. Relocation assistance is offered for international hires, and teams regularly onboard engineers from Korea, Taiwan, China, Vietnam, Indonesia, and occasionally Europe and North America.
Is there a separate process for new graduates versus experienced hires?
Yes, and applying through the wrong track is a common rejection reason. New graduates use lycorp.co.jp/en/recruit/newgrads/, which follows the Japanese shinsotsu cycle with cohort hiring, orientation, and internships. Experienced hires use lycorp.co.jp/en/recruit/career/, which is role-by-role and year-round. Pick the right portal before you apply.
How long does it take to hear back after applying on HRMOS?
Document screening typically takes one to three weeks depending on role volume. If you pass, a recruiter contacts you through HRMOS-generated email to schedule interviews; if you are declined, the rejection arrives through the same channel. Silence beyond three weeks is a soft signal to politely follow up via the contact listed on the role-specific privacy notice.
