Funabashi Sanbanze Seaside Park ふなばし三番瀬海浜公園
A tidal-flat park at the head of Tokyo Bay famous for spring clam digging and for sunsets with Mount Fuji silhouetted across the water.
About
Sanbanze is one of the last surviving natural tidal flats at the head of Tokyo Bay, and this park in Funabashi gives easy access to it. In spring and early summer families come at low tide for shiohigari, digging for asari clams in the mud flats (paid, season and tide dates published by the park). The rest of the year it is a quiet place for birdwatching, with plovers and dunlins feeding on the flats, and for sunsets: on clear days, especially in winter, Mount Fuji stands over the water to the west, sometimes with the sun setting directly behind it ("Diamond Fuji") around mid-February and late October. A small environmental learning centre explains the ecology of the flats. Swimming is not allowed.
Highlights
- Clam digging on the tidal flats in spring and early summer (paid, set dates)
- Mount Fuji across Tokyo Bay at sunset on clear winter days
- Shorebirds feeding on the flats: one of the bays best birding spots
- Environmental learning centre about the Sanbanze ecosystem
- Lawns and a playground for kids
Tips
- Clam digging dates depend on the tides: check the parks published calendar before going.
- Swimming is prohibited; wear shoes you can get muddy for the flats.
- Buses from JR Funabashi or Keisei Funabashi run infrequently on weekdays: check the timetable or take a taxi.
- For Diamond Fuji sunsets, check local reports for exact dates around October and February.
