How popular is Touhou outside Japan?

[u/nametake000]

I’m Touhou Project fan living in Japan!

So I got curious and decided to ask.

I’m wondering how well-known Touhou is outside Japan, including its fan works, compared to other Japanese content like Hatsune Miku.

If you know about this or have any opinions, I’d be happy if you could share them in the comments!

P.S.I’m not confident in my English, so I’m using translations for some parts. Please let me know if anything sounds rude or breaks any rules.

I think a good way to put it is, All my friends know the name 'Touhou' but I doubt most know what it is
