Renting an apartment in Japan: reikin, guarantors and the key vocabulary

Your first apartment in Japan is a big moment, and for many people the first culture shock too. Moving in costs several times the monthly rent, you need a guarantor, and the listings are full of vocabulary that no beginner textbook covers. In this article we explain the Japanese rental system step by step: from shikikin and reikin through the guarantor system to the key vocabulary that lets you read apartment listings yourself.

Why moving in is so expensive

The monthly rent itself is often fair in Japan. The shock comes with the one off costs: moving in frequently requires three to five months' rent upfront. This is made up of several items, one of which takes real getting used to from a European perspective: reikin, a "gratitude payment" to the landlord that you will never see again.

The guarantor system: hoshōnin and guarantor companies

Almost every Japanese rental contract requires a guarantor (保証人, hoshōnin) who steps in if you fail to pay rent. Traditionally that role falls to a family member in Japan, which is rarely an option for foreigners. The solution: a guarantor company (保証会社, hoshō gaisha) that acts as your guarantor for a fee. Many landlords now require such a company anyway, even from Japanese tenants.

The uncomfortable truth: landlords and foreigners

Honesty requires saying it: many Japanese landlords hesitate to rent to foreigners. The concerns usually revolve around language barriers, misunderstandings about rules like waste sorting, and whether communication would work if problems arise. That is exactly why Japanese skills and a polite manner at the viewing are your strongest tools. If you can answer the agent in Japanese, you defuse the most common concerns before they arise, and you unlock a much larger share of the housing market.

The key vocabulary for apartment hunting

Japanese apartment listings follow a fixed vocabulary. Know these terms and you can read listings yourself instead of depending on translations at the agency.
