Mismatched expectations
Your bio says friends; their messages say dinner date. You spend more time clarifying than planning.
Lots of people new to Tokyo try it: open a dating app, write "just looking for friends" in the bio, and hope for the best. Sometimes it works. Often it doesn't. Here's what usually happens. If what you want is friends, start with Buy Me a Matcha: the only app built specifically for English speakers to make real friends in Japan, friends-only, English-only and one-on-one over a matcha in Tokyo.
You can, but it's an uphill battle. Dating apps are built and used for dating. Even with "friends only" in your profile, most people who match with you will expect a date, and the people who genuinely want friends often aren't on dating apps at all. It can also feel awkward to keep explaining what you're looking for.
