Rain Making In Japanese Buddhism
Surprisingly, early records of rain making are mostly conducted by Buddhist monks rather than Shintō priests/priestesses. In “Tōdaiji-gusho” [東大寺具書] (Nara Period?), the very first Buddhist monk who performed rain dance was a monk from the Kingdom of Koryŏ [高麗/고려] by the name of Ekan [慧灌] (Asuka Period) who is the founder of Sanron Buddhist Sect [三論宗] in Japan¹. While his stay in Hōkō Temple [法興寺] (today’s Asuka Temple [飛鳥寺] (below) in Asuka Village [明日香村], Takaichi Dist. [高市郡], Nara Period) during the reign of Emperor Kōtoku [孝徳天皇], a series of draught struck Japan. This was when Ekan performed a rain making ritual as he recited verses from Sanron scriptures while wearing a blue dress which successfully brought rain.
Another less successful attempt was recorded from year 642 via “Nihon-shoki” when Empress Kyōgoku [皇極天皇] (594-661) instructed nobleman Soga-no-Emishi [蘇我 蝦夷] (586?-645) to conduct a rain making ritual on July 25th as he recited verses from Māhayāna Buddhist scriptures, but was instructed to desist after four days for the rain he managed to summon were mere drizzles and proper rain came only when the Empress prayed herself.
There’s also a legend² when two monks battled over who could bring down rain. In 1261, Shingon Buddhist Sect [真言律宗] monk Ninshō [忍性] (1217-1303) (below left) of Gokuraku Temple [極楽寺] (Kamakura City [鎌倉市], Kanagawa Prefecture) and another monk called Nichiren [日蓮] (below right) (1222-1282) who later founded Hokke Buddhist Sect [法華宗] fought each other to prove who’s teachings were superior. When Ninshō called upon the rain, it ended up summoning a tempest and failed, but delicate rain came down from the sky when Nichiren did the same; resulting to Nichiren taking the W.
Based upon these accounts, rain making became an integral part of Japanese Buddhist practice such as the manual for rain making together with drums and strawhats used in the ritual stored in Shindaibutsu Temple [新大仏寺] (Iga City [伊賀市], Mie Prefecture).

This is especially true for Jōdoshin Buddhists [浄土真宗] with their Nenbutsu-odori [念仏踊] which is a Buddhist choreography of rain making practiced even to this day such as the famous Taki-no-miya-nenbutsu-odori [滝宮の念仏踊] performed in Ayagawa Town [綾川町] (Ayauta Dist. [綾歌郡], Kagawa Prefecture).
