Leaving Japan early, company refusing to pay final salary before I go. What can I legally do?

I’m working for a company in Japan, and I have to go back to my home country in about two weeks due to a family emergency. Because of that, I won’t be completing my contract but I gave proper notice (two weeks) as required.

The problem is: I really need my final salary for the month I’ve already worked before I leave Japan. I asked the company to please deposit it into my Japanese bank account before my departure, but they said they can’t. They told me they’ll only pay me on the regular payday which is next month, after I’ve already left the country. They even asked for my home-country bank details so they can send it then.

But that’s too late I need the money now to deal with the emergency, and I thought that under Japanese law, companies are supposed to pay your outstanding wages within 7 days after you request it, if you’re leaving or your contract ends.

When I mentioned this to them, they just said “we can’t do that,” without any explanation.

I’m not trying to cause trouble. I just want to know what my options are here. I worked honestly, gave proper notice, and need the salary I earned.

So, I have a few questions for anyone familiar with Japan’s labor laws or who’s been in a similar situation:
1. Is it true that under Japan’s Labour Standards Act (Article 23), the company must pay your remaining salary within 7 days of your request after leaving?
2. If they refuse, what can I realistically do — like, can I go to the Labor Standards Office (労働基準監督署) and make a complaint even though I’ll be leaving soon?
3. Has anyone here actually done that before? How fast did they respond or take action?
4. Should I send a formal written request citing the law? Would that help pressure them to pay before I go?

I’m feeling really stressed because I have limited time, and this is a genuine emergency. I’m not sure how to handle this in Japan as a foreign worker, and I don’t want to just give up the money I rightfully earned.

Any advice, resources, or even sample message/letter I could send them would be so appreciated.

Thank you so much in advance to anyone who replies. 🙏
