Various Japanese websites actually have business hours, though it’s been getting better since 2020’s.

Imagine a banking app not allowing onboarding outside 8:30-18:30 Mon-Fri or a municipal site just saying come back at 8am.

The e-Tax system and various other government services still have these as well, mostly as daily maintenance windows. Some services use it to run data clean-up, consolidation, backup, etc. tasks so it’s not without reason.
