Suruga Bay, where the beach is located, is the deepest bay in Japan, reaching depths of over 2,500 meters.
Loggerhead sea turtles return to this specific stretch of coastline annually to deposit their eggs in the pebbles.
The beach is located on the Nishi-Izu (West Izu) coast, which is geographically distinct for its rugged volcanic topography.
Heda is historically famous for the construction of the 'Heda,' the first Western-style ship built in Japan following a 1854 tsunami.
Mihama Beach is a pebble-strewn coastline in the Heda district of Numazu, renowned for its unobstructed views of Mt. Fuji across Suruga Bay. The beach serves as a protected nesting site for loggerhead sea turtles during the summer months. Local conservation groups monitor the beach to protect egg-laying habitats. The shoreline is characterized by smooth, polished volcanic stones rather than fine sand. Visitors can view the Heda harbor entrance and the Izu Peninsula coastline from this vantage point. The area remains relatively quiet compared to popular sandy beaches in southern Izu. Clear days offer visibility of the iconic Fuji silhouette rising directly over the water.

Wear sturdy, closed-toe footwear as walking on the loose, medium-sized pebbles can be difficult in sandals.
Bring binoculars to scan the horizon for the Mt. Fuji view and local marine life.
Check local weather reports specifically for the Izu region to ensure visibility of the mountain before heading out.
Do not attempt to swim or approach the water during high surf, as the underwater drop-off in Suruga Bay is extremely steep.
Beach access areas may be restricted or cordoned off during the peak sea turtle nesting and hatching season to prevent human interference.
Do not disturb pebbles or fenced areas during turtle nesting season; keep noise levels low to avoid interrupting wildlife.
