Shinmaiko Coast
8 min readOverview & Attractions
Shinmaiko Coast is located in Mitsu-cho, Tatsuno City, Hyogo Prefecture, facing the Harima-nada Sea. Also known as Shinmaiko-hama, the area is characterized by a vast, shallow sandy beach and tidal flats that stretch approximately 1 km east to west. Situated within the Setonaikai National Park, it is a well-known leisure spot where visitors can immerse themselves in a beautiful natural environment.
History & Cultural Background
The area has long been cherished for its rich natural coastline. While historical records note a landslide in the area behind the coast in 1971, the site has since been fully developed and managed as a premier leisure and swimming destination. The region also maintains a vibrant local culture, hosting events such as the "Mitsu Sea Festival Sunset Festival," which celebrates local traditions and seasonal festivities.

Main Highlights
The most striking feature is the expansive, shallow sandy beach and tidal flats. This unique topography makes it an ideal environment for hands-on activities like clam digging (shiohigari). Additionally, during certain seasons, visitors may witness a breathtaking sight when the winter sunrise coincides with low tide, causing the light to reflect brilliantly off the remaining tide pools on the sand. During the summer, the area opens as a designated swimming beach, drawing crowds for seaside relaxation.
Seasonal & Time-of-Day Recommendations
Shinmaiko Coast offers different charms depending on when you visit. The peak season is during the summer (roughly June to September), when the focus is on swimming and beachside leisure. The tidal flats are also perfect for clam digging during specific seasons. In winter, visiting during sunrise can offer a stunning visual experience with light reflecting off the shoreline. We recommend checking the local tide tables and event schedules before your visit to maximize your experience.

Activities & Experiences
Activities here center around engaging with nature. A highlight is the clam digging experience; during certain periods, local associations release farmed clams, allowing visitors to enjoy collecting shells directly from the sand. Families and groups can also enjoy swimming during the summer season. Whether through seasonal events or simple seaside relaxation, you can experience the quintessential charm of the Japanese coast here.
Surrounding Area
There are several scenic spots to explore around Shinmaiko Coast within Tatsuno City. Nearby attractions include the Ayabeyama Plum Grove and the Mitsu Nature Observation Park (World Plum Park), where you can enjoy seasonal blooms. The Murotsu area is also a great addition to a local sightseeing route.
