Sanmaizu, Mudflat in Edogawa-ku, Japan.
Sanmaizu is a mudflat along Tokyo Bay's coast in Edogawa-ku where the seafloor becomes visible at low tide. The exposed ground consists of soft mud and silt that attract numerous creatures and birds seeking food in the shallow water.
The mudflat developed gradually through sediment carried by rivers flowing into Tokyo Bay over centuries. This natural formation created a shallow coastal ecosystem that has supported local communities for generations.
Local fishermen frequent Sanmaizu mudflat during low tide periods to collect various shellfish and small marine creatures using traditional fishing methods.
Low tide is the best time to visit when the mudflat becomes fully walkable. Bring sturdy waterproof footwear since the surface is slippery and soft throughout the area.
The sediment composition of Sanmaizu includes specific minerals that support specialized microorganisms, contributing to the local marine food chain.
