Traditional female free diving in Japan

Also depicted in "Tampopo" (1985) https://www.imdb.com/title/tt0092048/

Probably needs a NSFW tag for some tame black and white photos with nipples.

I couldn't guess from the title whether it was female-free or free-diving. It's the latter, which is cool.

Whoa there. You know you've worked from home too long when you see a naked body unexpectedly and immediately hit back. :D
