Karakusa 100

Quick answer：

Karakusa 100 refers to the 100 rocks arrangement in a traditional Japanese dry landscape garden, known as 'karakusa-zaka.' This style of garden, which features carefully placed rocks and raked gravel to represent mountains, rivers, and islands, is a form of Japanese Zen garden. Karakusa-zaka is particularly associated with the Ryoan-ji temple in Kyoto, which is famous for its iconic rock garden with only 15 rocks.
