Saturday's peaceful postcard

This undated postcard (probably from the 1960s) features the "Waiting Room for ceremonial tea" at the Mikyato Hotel in Kyoto, Japan, a city that dates to 794. It's a beautiful location, with its waterfall, boulders, bushes, gravel and small structure that blends perfectly with its surrounding. It believe it's called a chashitsu, but please correct me if I'm wrong.

According to Wikipedia:

"The term chashitsu came into use after the start of the Edo period (c. 1600). In earlier times, various terms were used for spaces used for tea ceremony, such as chanoyu zashiki (茶湯座敷, "sitting room for chanoyu"), sukiya (place for poetically inclined aesthetic pursuits [fūryū, 風流]) such as chanoyu), and kakoi (囲, "partitioned-off space"). An account stated that it was the shogun Ashikaga Yoshimasa who built the first chashitsu at his Higashiyama villa in Kyoto. It was described as a small room of four-and-a-half tatami and was separated from the main residence."

This location may still exist, though it's surely been modified over the decades. And of course tea ceremonies for tourists are much more commercialized. It's likely there are multiple hotel-based ceremonial tea room experiences offered in Kyoto. This website for Miyako Hotel Kyoto Hachijo offers a "Japanese tea ceremony experience wearing kimono" for 10,000 yen (about $64 today). 

And I found a 2023 article by The Mainichi newspaper that features some photos that look like they might be of the same location shown on this postcard.
