There are many valid reasons for yonige(night run away) or johatsu(literally evaporation) in Japan, but there are pernicious side effects.

Loans and leases in Japan most often require a guarantor. If the primary loan holder disappears, the guarantor is stuck having to repay the loan or pay out the remainder of the lease agreement.

I personally know a family devastated when they found themselves on the hook paying out a loan for a close friend they had known from childhood while trying to build their own business.
