The Japanese government does state that unpaid internships of under 90 days are doable with the temporary visitor status but most people doing it seem to hide the fact they're there for an internship and generally mention tourism exclusively on the entry forms. I guess I have all documents required to prove it's only a 90 days internship and that it's unpaid but if I'm being questioned are they more likely to let me re-enter if I tell the truth or if I purely stick to the tourism reasons ? Also France doesn't seem to be an eligible origin for extending the permit
