The shrine's name comes from a 'chūkei' (folding fan) discovered during 1675 renovations. Since fans widen toward the end, they're called 'suehiro' (widening末広), symbolizing prosperity and good fortune.

The shrine once served the Yoshiwara pleasure district that existed in Ningyocho until 1657's Great Fire. After Yoshiwara moved to Asakusa, locals continued worshipping here as their neighborhood guardian.

Yomoyo Inari enshrines a real Edo-period midwife who rescued abandoned children and cared for working mothers' babies. Grateful townspeople deified her after death, building a shrine within the grounds.

Ancient records confirm the shrine existed by 1596 during the Azuchi-Momoyama period, though its exact founding date remains unknown. The current building was reconstructed in 1947 after WWII air raids.
