Hello Grüezi.

I am Japanese. I'm looking for a English-tandem partner in Basel.
My English skill of pronunciation and grammar need to improve before learn German.
Is anybody interested in Japan and want to learn Japanese language?
I think I can teach you Japanese greetings and Hiragana, Katakana and some useful Kanji (chinese character).
I am happy if we can exchange language lessons.

こんにちは and welcome to the forum.

You can find people who live in Basel using the member search function, specifying the spoken language(s) in the two native and foreign language fields. Not everybody fills in that information in their profile (myself included), but a sufficient number do so that you should be able to find some people.

I also advise you to post a tandem request in this thread.
