The 'floating' utility poles that once defined the landscape were originally installed to supply electricity to remote clam-harvesting huts.
The tidal flats at Egawa are part of the larger Kisarazu coastal area, which is one of Japan's most productive regions for Asari (Manila clam) harvesting.
The Tokyo Bay Aqua-Line, a massive bridge-tunnel combination, is clearly visible from the beach and provides a distinct architectural backdrop.
The geography of the beach changes significantly within a single day due to the high tidal range in this part of the bay.
Egawa Beach Shiohigari is a coastal site in Kisarazu, Chiba, primarily recognized for its expansive tidal flats and organized clam-digging activities. The area gained viral fame for its wooden utility poles stretching into the Tokyo Bay, which created a visual effect reminiscent of the animated film Spirited Away. While many of these iconic poles were removed in 2017 for safety reasons, the location remains a popular destination for seasonal clam digging. Visitors can walk out onto the exposed seabed during low tide to harvest Asari clams. The site offers expansive views across the bay toward the Tokyo skyline and the Tokyo Bay Aqua-Line. The beach is managed by the Egawa Fisheries Cooperative. It serves as an active hub for traditional shellfish harvesting practices in the region.

Bring a change of footwear, such as waterproof boots or sturdy water shoes, as the mud can be deep and shells are sharp.
Check local tide tables before departure, as the tidal flats are only accessible during low tide.
Bring your own small rake and a net bag for your harvest, though rentals are often available on-site.
Attempting to dig during high tide or wandering too far into the bay as the tide can return rapidly.
Clamming season typically operates from spring through early summer; the beach is inaccessible for harvesting outside of this seasonal window.
Clean your equipment thoroughly before leaving; do not harvest undersized clams as specified by local cooperative regulations.
