For foreign residents in Japan
It isn’t a hundred small problems.
It’s one problem, in order.
City hall, health insurance, a bank account, a phone, a lease, a driving licence. Each one is small enough to put off and tangled enough to get stuck on. mondainai works out which ones apply to you, puts them in the order they have to happen, and tells you exactly what to carry to the counter.

The national procedure is the same everywhere — it is set by national law. What changes between municipalities is which counter, which hours, and what it costs. 29 cities are set up so far, starting with Tokyo’s 23 wards.
Wrong information is worse than none
Bad guidance here has a real cost: a morning of annual leave, a train fare, and a second trip to the same building. So every procedure carries its verification state in the open — who checked it, when, and against which official page.
Where we do not yet have detail for your city, the page says so and sends you to the ward office’s own site. Otomo, the assistant, answers only from this material and cites the step it came from. It will tell you it does not know. It will not invent a form name.
Most of the content is still marked unverified. That label is accurate, and it stays until someone has actually checked the source.
