http://www.ivebeenthere.co.uk/ Welcome to Been there. Your tips on the places you know - that you love, live in or have just visited - are what make this guide. http://www.ivebeenthere.co.uk/tips/21137
Inside is a selection of different flavour natural spring hot pools, sauna, steam room, cold pool, and then a lovely garden-set rotenburo outside.

Once you've bathed (usual caveats about Japanese bathing apply - shower first, so you're clean when you get in the pool) you can slip into your yukata and pop upstairs. A restaurant, bar, smoking terrace, and relaxation room await. The reclining chairs with the birdsong tweeting out of the speakers in the headrest are particularly good for a gentle sleep.

As far as I can tell there is no time limit on being there - the last visit we spent about 5 hours, bathing, sleeping, eating, bathing etc.

Super clean, very luxurious and not as gimmicky as some of the other themed onsen in Tokyo city. Worth a go if you can't get out to a countryside onsen and do it early in your trip, because after your first try you'll definitely want to do it all again.]]> http://www.ivebeenthere.co.uk/tips/21137
