🇯🇵Japanvs.🇰🇷South Korea

Japan and South Korea are the two most overlooked property markets in the American expat conversation, which is strange because both allow unrestricted foreign ownership — you can buy a mountain in Hokkaido or a house in the Gangnam hills with no bank trust, no visa requirement, no holding period, and no foreign-buyer tax. That alone puts them ahead of Canada, Australia, New Zealand, Mexico and Switzerland on pure ownership friction.

Japan's defining quirk is depreciation. Wooden residential houses lose ~50% of their value in 20 years and effectively zero out at 30. This is both horrible (you can't treat it as an investment) and beautiful (you can buy a perfectly livable 1980s house in a Tokyo suburb for $80-150K cash). Our dataset shows Japan's median listing running noticeably below Korea's because of this, heavily weighted toward older suburban houses and the "akiya" (abandoned rural house) inventory. Tokyo and Osaka central condos are a separate market — those hold value and cost roughly the same as comparable Seoul districts, $400-800K for a 2-bedroom.

Korea is the opposite. Apartments ("아파트") in Seoul hold value aggressively — the "gangnam unnie" stereotype of a woman whose entire wealth is in her apartment is economically rational. The jeonse system (lump-sum multi-year deposit instead of rent) distorts the market in ways foreigners find incomprehensible. Our Korea dataset skews toward Seoul, Busan and Daegu condos, mostly 15-30 year old buildings with pricing around $200-500K for family-sized units.

Language barriers are serious in both. Japanese written bureaucracy is arguably worse than Korean — every form is hand-stamped, and rental applications require a Japanese guarantor (co-signer) that a foreigner without deep ties cannot provide. This makes the Japan DNV (only 6 months, no residency benefits) functionally useless; you need the Business Manager visa, a Highly Skilled Professional visa, or an employer sponsorship to actually live there. Korea's F-1-D "Workation" DNV is more generous (1 year, extendable to 2) but income threshold is high (~$65K/yr) and it still does not let you open a regular bank account.

Pick Japan if you want to buy a physical house outright with cash and you don't care about resale. Pick Korea if you need an apartment that holds value in a real urban economy and you're willing to navigate the language and jeonse system. Neither is a beginner's expat destination.
