Shuffle dance schools or groups in Tokyo.

Lately i’ve taken an interest in shuffle dance, practicing on my own from YouTube videos.
I asked this in the Tokyo subreddit, but I thought to try here too.

Are there any dance schools that specializes in shuffle dance?
Are there any fun groups that meet weekly to practice shuffle dance? I searched Meetup already but no such groups are found.

I want to join the shuffle dance community in Tokyo, but not sure how to find them.

Does anyone have any advice or information they can share?

Thank you
