Hōjōki

, variously translated as An Account of My Hut or The Ten Foot Square Hut, is an important and popular short work of the early Kamakura period (1185–1333) in Japan by Kamo no Chōmei. Written in March 1212, the work depicts the Buddhist concept of impermanence (mujō) through the description of various disasters such as earthquake, famine, whirlwind and conflagration that befall the people of the capital city Kyoto. The author Chōmei, who in his early career worked as court poet and was also an accomplished player of the biwa and koto, became a renunciant in his fifties and moved farther and farther into the mountains, eventually living in a 10-foot square hut located at Mt. Hino. The work has been classified both as belonging to the zuihitsu genre and as Buddhist literature. Now considered as a Japanese literary classic, the work remains part of the Japanese school curriculum.

The opening sentence of Hōjōki is famous in Japanese literature as an expression of mujō, the transience of things: The flow of the river never ceases, And the water never stays the same. Bubbles float on the surface of pools, Bursting, re-forming, never lingering. They’re like the people in this world and their dwellings.
