Japan vs South Korea: which is easier to move to?
A straight side-by-side on the eight things that decide it — work routes, study, family, residency, citizenship, cost, healthcare and jobs.
| 🇯🇵 Japan | 🇰🇷 South Korea | |
|---|---|---|
| Region | East Asia | East Asia |
| Population | roughly 123 million | roughly 51.7 million |
| Foreign-born | around 3% of residents | around 4-5% of residents |
| Language(s) | Japanese | Korean |
| Currency | Japanese yen (JPY) | South Korean won (KRW) |
| Work Visas | Working in Japan means holding one of the work-permitting statuses of residence, and in nearly every case an employer in Japan must first obtain a Certificate of Eligibility from a regional immigration bureau before a consulate will issue the visa. The broadest professional category is Engineer/Specialist in Humanities/International Services, which commonly requires either a relevant degree or a substantial number of years of related experience. Full guide | Korea has no single work visa. It has a series of lettered employment statuses, each defined by activity: E-2 for language teaching, E-7 for specified professional occupations, E-9 for manual labour under bilateral agreements, D-8 for corporate investment and D-10 for job seeking. Which one applies is determined by the job, not by the applicant's general qualifications. Full guide |
| Student Visas | The Student status of residence is sponsored by the accepting institution, which applies for the Certificate of Eligibility, and it carries permission to work part-time only if a separate permission to engage in activity outside the status is granted. Its main strategic value is the post-graduation job-hunting route, which allows graduates to remain in Japan while searching for work and then convert to a work status. Full guide | The D-2 status covers degree study at an accredited Korean institution and the D-4 status covers language courses and other non-degree programmes. Study is a recognised route onward: graduates may move to a D-10 job-seeking status, and time spent studying counts toward the points and residence requirements that follow. Full guide |
| Family & Spouse Visas | Japan distinguishes sharply between the spouse of a Japanese national, who holds a broad status with no restriction on the type of work permitted, and the dependant of a foreign resident, who holds a status that does not itself permit work. That distinction, rather than any income threshold, is what decides how a family actually lives here. Full guide | The F-6 status covers the foreign spouse of a Korean national and is the most privileged family route, carrying open work rights and the shortest path to residence and citizenship. Dependants of foreign workers hold the F-3 status, which permits residence but not employment without a separate change of status. Full guide |
| Permanent Residency | Ordinary permanent residence generally follows around ten years of continuous residence, of which roughly five must have been on a work or residence status rather than as a student, alongside good conduct, independent means, and evidence that tax and social insurance obligations have been met. The exceptions are substantial: spouses of Japanese nationals and Highly Skilled Professional points holders reach it far sooner. Full guide | Korea has two long-term statuses that matter. F-2-7 is a points-based residence status awarded for age, education, income, Korean language and other factors, and it removes much of the employer dependence of an E status. F-5 is permanent residence, generally reached after roughly five years, with the conditions varying considerably by the status held beforehand. Full guide |
| Citizenship | Naturalisation is governed by the Nationality Act and administered by the Legal Affairs Bureau rather than the immigration authorities. The ordinary requirement is around five years of continuous residence with lawful status, sufficient means, good conduct, and capacity — and Japan does not permit adults to hold dual nationality, so the original citizenship generally has to be given up. Full guide | Naturalisation generally requires roughly five years of continuous residence with an appropriate status, a written examination, an interview, and evidence of income and good character. The defining feature is that Korea does not generally permit adults who naturalise to keep their previous nationality, and requires renunciation, with dual nationality allowed only in narrow listed cases.

| Cost of Living | Japan is markedly cheaper than most people expect, and central Tokyo is the exception rather than the rule. Rent outside the central wards, everyday food, and public transport are all modest by developed-country standards, and a weak yen has widened the gap for anyone whose income is earned abroad. The costs that do surprise arrivals are the up-front charges on a rental contract. Full guide | Day-to-day costs in Korea are moderate: food, transport, utilities and healthcare are inexpensive relative to Western Europe or North America. Housing is where the money goes, and it goes in an unfamiliar shape, because the rental market runs on very large deposits rather than on monthly rent alone. Private education is the second large line. Full guide |
| Healthcare | Health insurance is compulsory for residents, delivered either through the employer-based Employees' Health Insurance system or through municipal National Health Insurance for everyone else. The insured pay a share of the cost at the point of use, commonly around 30%, with a monthly ceiling that limits exposure to catastrophic bills. Enrolment in the pension system runs alongside it, and departing residents can claim a lump-sum withdrawal under published limits. Full guide | Korea's National Health Insurance is compulsory, near-universal and inexpensive relative to the quality of care it buys. Foreign residents staying six months or longer are generally required to enrol, either through an employer or as a local subscriber, and enrolment is not optional even for those who would prefer private cover. Full guide |
| Finding a Job | The Japanese labour market is tight, and shortages are acute in care, construction, logistics, hospitality, and parts of engineering. The constraint on foreign professionals is rarely demand and rarely qualifications: it is Japanese language ability, together with hiring conventions that favour long tenure and internal progression over lateral entry. Full guide | The Korean labour market for foreigners divides sharply. Language teaching and manual labour under the Employment Permit System recruit openly and at volume. Professional employment in technology, manufacturing and finance exists in real numbers but is difficult to enter without Korean, because hiring, documentation and daily work are conducted in Korean at almost every firm outside a handful of multinationals.
