The tidal flats at Futtsu span a significantly larger area than typical urban beach parks, exposing vast stretches of seabed at low tide.
The local fishing cooperative periodically monitors the water quality and sand conditions to manage the health of the shellfish beds.
The clams found here are primarily Manila clams, which thrive in the brackish, nutrient-rich environment of Tokyo Bay.
Because the tides vary daily, the available area for clam digging shifts significantly, requiring the schedule to be adjusted to the lunar calendar.
The facility is designed as an experiential site where participants gain insight into traditional coastal gathering practices.
Futtsu Coast is one of the largest clam digging grounds in Chiba Prefecture, offering expansive tidal flats that emerge during low tide. The facility is managed by the local fishing cooperative, which oversees the seeding of the area with clams to ensure sustainable harvests for visitors. Digging typically involves using hand tools to rake through the wet sand to uncover Asari (Manila) clams. The site features basic amenities including foot-washing stations and changing rooms for visitor convenience. Visitors are required to follow local catch weight limits to preserve the clam population. The area is situated along the Tokyo Bay coastline, providing views of the bay and Mount Fuji on clear days.

Bring a change of clothes and a towel, as you will likely get muddy or wet during the process.
Wear rubber-soled water shoes or thick tabi boots to protect feet from sharp shells buried in the sand.
Check the tide charts before departing, as the tide level determines whether the flats are accessible for digging.
Avoid arriving without checking the specific day's tide schedule, as the beach may be entirely underwater during high tide.
Operations are strictly seasonal, typically running from spring through early summer, and are entirely dependent on the tidal cycle and daily weather conditions.
Use only designated tools provided or approved by the site; do not bring large industrial rakes; strictly observe the weight limit for collected clams.
