Courtyard Marriott Osaka Honmachi has an onsen.

Yes, I like this find. Thanks. I will mark it down as potential for my next trip when I take in Yakayama, Kushimoto and Ise.

Is it not the same as Lake Biwa Marriott?

Thanks for the tip.
I am looking for a more natural setting with mountains, river, lake or beach around. This Courtyard can still be a good place to stay for a night or 2 during an exhausting trip.
I am quite happy that Marriott in the last few years had added so many properties in Japan.

Suiran Kyoto is nice and a lot of rooms have private outdoor bath.

You mentioned small town excursions, and Omihachiman is the place to go when staying at the Lake Biwa Marriott.
Bit of a hassle without a rental car though.

Consider visiting La Collina (cake) and Two Rabbits (beer)

Thanks for confirming Omi. It is on my list.
Cake & beer sound real good. Thanks.

I recommend the Lake Biwa property, just a solid hotel professuonally run, in a wonderful area, go to Tiffany in Omihachiman for great Omi beef, better and cheaper than Kobe beef !

Agreed, after having styed there 2 nights. We did have an in-room onsen (actually in the balcony. In/out of balcony via a sliding glass door. We put it in good use.

Note this down for possible future adventure. Good to know that Omi beef quality and price champ over Kobe beef.

My two experiences have been Sheraton Kobe Bay - this is a public onsen with free access for Elite guests staying at the hotel - and Shisui - I am not sure if there is a public onsen, but my suite had an onsen in the bathroom. I believe Suiran has a similar setup for some of their rooms and suites.
