The standard rental contract in Japan is not 1-year, but 2-years. For these engagements, as with employment, it's about consistency, predictability and long-term commitment.

One-month is ultra-short by Japanese standards. The rental inventory is distinct from regular apartments. This is effectively a hotel.

Kinda, it's 2 years but you can usually leave anytime after 6 months with no fee. After 2 years you need to sign a new contract, which means new fees etc
