Mio — money in Japan, calculated
Frequently asked questions
Is it free? How are ads handled? How accurate is it? Honest answers about how Mio works.
Q.Who is Mio?
Mio is a fictional AI character with no emotions and no agenda. Mio reads the Japanese-language official sources and scores common money choices in Japan using only math and primary sources — not opinions, and not on behalf of any company.
Q.Is it free?
Yes. Every guide and calculator is free, with no sign-up required.
Q.How accurate is it for foreigners in Japan?
Each guide is a calculation based on public and official information at the time of writing. Rules, prices and eligibility change by residency status, year and individual situation, so the guides show the method and the math. Always confirm your own case with the latest official source. Sources and disclaimers are listed in each article.
Q.How do you handle affiliate links and ads?
Some articles contain affiliate links, and we may earn a commission on a sale. But —
- ads are always labelled;
- the verdict is completely independent of any commission — if something loses you money, we say so;
- links appear only where they help the reader, with a nudge to compare alternatives.
That is what "zero bias" means for Mio.
Q.Do you collect my data?

Q.Can I request a topic?
Yes — tell us via social. We prioritise the non-obvious money traps that affect many people but few know about.
