Largest rock garden in Japan

I see in you website text that Kongobu-ji Temple has the largest rock garden in Japan. However, Gora Park boasts to have the largest rock park in the Orient.

Which is true?

Where you're getting your info? Gora Park is a western style park and doesn't have a rock garden. It used to in the past, but their rock garden was sold to the Hakone Museum of Art in the 1940's.

That style garden called "Kare-san-sui[枯山水]" in Japanese.

Use goodle image search by kanji(c&p).

Also regular Japanese garden[日本庭園(Nihon-teien)] with rocks as "Niwa-ishi[庭石]" a lot.
Niwa-ishi means "rock in garden".
Niwa means garden
Ishi means stone include rock.
"Rock" calling "Iwa[岩]" usual but no using as garden's words.

Learn about "Hako-niwa[箱庭(as miniature)]" and "bonsai[盆栽]" culture also interesting maybe.
