Can I stay in a hotel when I go to Japan alone 15?

I'll look it up for you on the Japanese website. This situation may be more complicated.

Although Japan stipulates that minors can stay in hotels alone as long as their parents write a letter of guarantee or contact the hotel in advance.

But after all, this is a Japanese rule.

For outsiders, even if lz's parents wrote a letter of guarantee, it is difficult for the hotel to judge whether it is true or not. So it is very likely to be rejected.

However, this is only a rule. In reality, many hotels don't care about these for profit.

So if lz can speak Japanese, you can call to ask whether the hotel you want to book accepts minors to book separately.

If you can't speak Japanese, you can find a hotel reservation center like Freetravel and ask them to contact the hotel for confirmation.

This should be the most reliable way.

Above, I hope I can help lz.

In addition, the specific method of booking minors in Japanese hotels (Japanese) is attached. For lz reference.
