During my trip to Beppu last 2008 with N, we accidentally found this Mud(Doro) Onsen as we were walking down the street. Actually N and I were a little lost and the bus were not arriving so we just started walking. This is the reason why I don’t make itineraries when I travel, getting lost is part of the fun 🙂
Anyway I digress. Pictures were not allowed inside and N and I were excited to check the Onsen that we totally forgot to get a picture of anything. I finally found their website and name ( after all this years).
Onsen Name : 明礬温泉保養ランド : Myouban Onsen Hoyo Land.
I also found some picture on OnsenJapan website.
Price: 1050 yen for adults and 750 for kids.
It is still one of the most unforgettable onsen experience I have so far. I highly recommend it if you are in the area.

This may sound naughty, but when I checked out their website and scrolled down the photos.. I don’t understand them anyway, and there goes this sexy naked guy who’s covering ‘his’.. I now got a huge reason to drop by and purposely get lost. :>
haha ha, good luck and have fun 😀
Oooh a mud onsen sounds like loads of fun!! I have never seen one before but would love to try it out1
I do hope you give it a try when you got the chance to visit Beppu, it’s definitely worth it.
Will have to remember that if I visit!
it’s definitely worth visiting
