QB is possibly feeling slightly better. Unable to commit to actual feeling yet.
Thunderbird Shinkansen to Osaka
At the station picked up a few tax-free items. What is the note is the plastic bag? It says we must keep the items in the plastic bag until we leave the country. Have not seen anywhere else in our shopping adventure.
The route passes through several Onsen towns each with their unique public baths.
In general the term hot spring refers to a spring containing at least 1 component in the 19 kinds of essential substances listed in the Hot Spring Law or containing an existing solvent substance with more concentration than in the specified amount or mineral water/hot water having a temperature superior to 25 degrees.
Washing stations on the right hand side. Soap up wash, hair, face, whole body with cloth and when completely clean then you go into the type of bath on the left. Many places have just one large pool. I have seen several with hot and cold water. Temperature generally about 104 to 106.
We have been to Onset towns that have had seven different public baths each with their own unique, waterfalls, rocks, etc. see blog from 2015 for that visit great food great service fabulous baths.
Okonomiyaki and yakisoba (greasy noodles under salad). Teppan prep and teppan serving.
Shopping for dinner at the bottom of Takashimaya
Fauchon first.
Spa, of course, prior to dinner. Big and warm 106 F
Not especially hungry after that big greasy lunch

Hope all are getting better – eating Yakisoba and Okonomiyaki are positive signs :-).
The images of the baths look more like the traditional city-based bathhouses – SENTOs (as opposed to hot spring onsens – not much hot spring activity in downtown Osaka, or Tokyo, for that matter). They usually have the main baths sectioned rather than one big tub/pool (easier to clean and keep operations going). Tokyo has many which are sort-of a sub culture; they disappeared rapidly as folks got their own modern plumbing with baths at home.
I periodically see efforts by (usually) the Bathhouse Operators Associations (or whatever) to market them to younger folks (new designs, safer entries, stricter rules, etc) – some cool Tokyo versions – https://japanobjects.com/features/tokyo-sento
Forgot to mention, technically the Thunderbird is not a Shinkansen – it is a special Limited Express. The main distinction is that Shinkansen’s run on completely different tracks than other trains operated by the JR groups. The Thunderbird, which I’ve taken a few times, including the last trip, is a great train through lots of rice fields and mountains – https://photos.app.goo.gl/YLWCR428sX9d8Wcn6
