Foreigners can rent houses in Japan, but there are some caveats to keep in mind. Most people in Japan rent apartments rather than houses due to the scarcity and expense of land. Many landlords require tenants to have a Japanese guarantor or co-signer, which can be challenging for foreigners who don't have any Japanese connections. Additionally, the language barrier can make it difficult to find a place without assistance from a bilingual friend or professional. However, with proper planning and preparation, it is possible for foreigners to rent houses in Japan.
