Looking for Marriott with onsite onsen
 

I've done some search on this thread as well as on the web to no avail.
Besides Fuji Marriott Hotel Lake Yamanaka (which I don't consider as authentic onsen), are there any Marriott property in an onsen town?
Appreciate your input.

Ritz Carlton Nikko

Hotel Mitsui, Kyoto

https://en.m.wikipedia.org/wiki/Onsen (hot springs and the bathing facilities and traditional inns around them)

RC Reserve Higashiyama, Niseko.

Courtyard in Hakuba
Marriott Shirahama
They both have in room baths too

Also
Westin Miyako Kyoto
Kobe Bay Sheraton

This one is pretty nice

Westin rusutsu
Marriott Biwa lake
Marriott Izu shuzenji

Thank you. Will check it out.

Thanks.

Will check it out, even though I have been to Kyoto in all seasons multiple times.

Thank you. Will check it out.

I actually have a booking at the Marriott Biwa already, knowing that they pipe in the hot spring water. Ironically, my choice of Marriott Biwa is not for onsen, but to explore nearby villages, in search of photo-ops.

I will check out the other 2 properties. Thank you so much.

Thank for the info. With yours and other inputs, I will spend some time researching. To be more specific, I am looking for a more authentic onsen experience, one that is located in an onsen town would be preferred.
For example, couple of years ago, I did Noboribetsu Onsen in Hokkaido. That was amazing (of course that is not a Marriott property). So now I try to locate a Marriott in a similar environment.

Shirahama is a real onsen/beach town.
