Shirahama Onsen 白浜温泉 — Wakayama
In-room bath + reservable private bath
A small inn that owns its own source: the pot-shaped reservable bath is free for every guest, and the detached special room has its own free-flowing hinoki bath.
You get both kinds of private here — a bath of your own, and reservable ones for the long soak. Most guests use both before checkout. You probably will too.
Private-bath and water facts were checked against the property's official site and Japanese booking pages in November 2026. Room plans change — confirm the private bath is included in the plan you book.

Several rooms carry their own garden or balcony open-air bath drawn from the inn's natural hot spring — in the Kainanso special room it pours straight from the source — a short stroll from Shirarahama beach.
The bookable private bath pairs an indoor tub with its own small open-air bath in the hotel's gentle sodium bicarbonate spring water — reserve it at reception on the day.
Five reservable baths look straight down at the Pacific, and the premium rooms carry their own onsen view baths — big-resort scale with a private soak whenever you want one.
