Here’s a link to an article about Suizenji Jojuen (Garden) with some notes about the “mini Mount Fuji.” The article is correct; the grass-covered feature is indeed intended to look like Fuji-san as viewed from the Tokaido. What the article doesn’t say is that there’s a term for this kind of man-made garden mountain: tsukiyama (築山; literally “built mountain”). The mountain in Suizenji Jojuen is a representative example of the technique. In fact, if you look up the Japanese term on Wikipedia you’ll find a picture of Suizenji Jojuen. – Kirk
