Had a quick peek at Japan's Route 207 YT page to see if there was anything new. There was.
Some of it's in 4K, too - looks like you're practically in the pit with 'em.

Amazing find, thanks for pointing out that they had new clips posted! I had forgotten they had a youtube page, ...those 1080p 60fps resolutions on the 4K clips are mind blowingly real looking, right in the action in deed!

Thank you for the compliments for my videos.

Bath #3,4,5 and Doronko #24 are also in 4K 60fps though not specified in the title.

I hope you enjoy the image quality.

Wow that's mud in the bath?
Always thought it was chocolate syrup or something as it looks so creamy
Can I ask what type of mud or clay it is?
Are these all available to buy?
Just amazing work

They are. And well worth it.

Thank you for the compliments.
Bath videos use artificial near-mud material made of water, soil pigments, and CMC.
It is easy to prepare and clean up.

If you prefer natural mud, I hope you enjoy Doronko videos.

Ah ok not sure what CMC is but it sure looks great
The doronko ones are all outside?
Did these include those head first diving and total submersion ones?

Doronko videos are all outside.
They include total caverages, but don't include head first diving and total submersion.
Sorry if I'm wrong about your question.

Please see also the sample pictures on my website.

I love your work; it is very erotic! Could you focus a little more on the models' bare feet? Thanks!

I'm sorry that I'm less concerned about barefoot, but there are some photos.
I hope you like it.
I'll focus a little more on the models' bare feet in the next shooting if possible.

Hey Route207, I'm a big fan of your work. Is there any chance of a nude Doronko video? I'd love to see more girls diving off that boardwalk.

Thank you for the compliment.
I think there will be no chance to shoot nudity in the public place such like the Doronko park because it is very risky behavior under Japanese law.

FYI, Kamikaze-san shoots Doronko videos too.

Like the Doronko videos-The models are most attractive & always look as if they were enjoying the mud
