Home of the Sannō Matsuri, one of the three great festivals of Edo along with the Kanda Matsuri and the Fukagawa Matsuri, and historic patron of the district of power: the Diet and the Prime Minister's residence stand next to it. The grand festival is held every two years, alternating with the Kanda Matsuri: in 2025 it was Kanda's turn, in 2026 it is the Sannō's.
Shinto shrine on the hill of Nagatachō, guarded by pairs of stone monkeys instead of the usual komainu. The Sannō Matsuri brings out 55 floats and involves over 160 neighbourhoods of the city; it is held every year in June but alternates a ‘grand’ year (本祭, with a procession) and a ‘small’ one (without).
ℹ️ 2026 is a grand festival year: the Sannō Matsuri runs from 7 to 17 June, with the Shinkō-sai procession on 12 June (about 500 people in period costume, a 300 m procession, through the Imperial Palace, Tokyo Station, Ginza, Nihonbashi) and the Shitamachi Rengō Tōgyo (16 neighbourhood mikoshi) on 14 June. The treasure museum (宝物殿) is open 9:00–16:00, free entry, all year round. Check the opening hours of the main grounds separately.
