Raked Gravel and Rock
Considered quintessentially Japanese, gardens with raked gravel and rock are ubiquitous in Japan. Generally called "karesansui" they are often known in English as "Dry Gardens". Heavily associated with Zen, they are found not just in Zen temples but almost anywhere, secular or sacred.
The first photo is from Kanyoji Temple in the mountains of Yamaguchi Prefecture. I believe it was designed by Mirei Shigemori, one of the great garden designers of the 20th Century. The second photo is from the Yuushien Gardens on Daikon Island in the Nakaumi Lagoon between Shimane and Tottori. An excellent garden well worth a visit.
This third one is within the entrance area to a hot spring resort in the Okuizumo area of Shimane.
There is no shortage of karesansui gardens in Kyoto, but this 4th photo shows one of the lesser known ones. It is in front of the main hall of Shogo-in, a monzeki temple, which means it was home to a member of the imperial family.
This last one is also not such a well known garden, bgut also one that is well worth a visit. It is in the grounds of the ruins of Tokushima Castle and was part of the palace there.
