Abstract: Asakusa Kannon, Osu Kannon, Tsu Kannon
Note: This article is a response to the question What are the three great Kannon in Japan?? on MOJi Q&A.
Asakusa Kannon: Kinryuzan Sensoji Temple
Osu Kannon: Kitanozan Shinpukuji Hōshōin
Tsu Kannon: Eijizan Kannonji Daihōin
Source: What are the three great Kannon in Japan!?
These three can be mentioned together because they serve as large Kannon temples (according to Three Great Kannon of Japan - Wikipedia)
P.S. My apologies, it turns out that "Sensoji Temple" is the temple of Kannon Bodhisattva.
Additionally, I checked some other temples that I have some impression of:
"Kiyomizu Temple" is also a temple of Kannon, and the "Eleven-faced Thousand-armed Kannon statue" enshrined there is a very important cultural relic (Chongqing person: !? I must go see it)
"Ryoanji": The main deity is "Shakyamuni Buddha"
"Yakushiji": The main deity is also a Buddha, but "Yakushi Nyorai"
Finally, let me add the "Four Great Famous Mountains of Chinese Buddhism":
Mount Wutai in Shanxi - Manjushri Bodhisattva
Mount Putuo in Zhejiang - Avalokiteshvara Bodhisattva
Mount Emei in Sichuan - Samantabhadra Bodhisattva
Mount Jiuhua in Anhui - Ksitigarbha Bodhisattva
