Counting the waves…
Counting the waves…
The drive along Route 244 reveals Hamakoshimizu Beach gradually, a charcoal-gray arc pressed between low dunes and the gunmetal Okhotsk Sea. You park on gravel near a weathered breakwater, stepping onto sand that's coarse underfoot, flecked with obsidian fragments from ancient eruptions. The beach curves northeast for nearly a kilometer, backed by wind-sculpted grasses that hiss in the constant maritime breeze. In winter, drift ice from Siberia piles along the shore in blue-white mounds; come July, the same water stays cold enough to make your ankles ache. Few structures interrupt the landscape—a small fishermen's hut, a faded sign warning of currents, wooden tetrapods stacked against storm surges. Seabirds work the tideline, probing for sand lance and shellfish exposed by the receding water. The horizon stretches unbroken except for the occasional longliner heading toward Abashiri's harbor, twenty kilometers south. You might spot Ezo deer wandering down from the forested hillsides at dawn, leaving delicate prints that the tide erases by mid-morning. This isn't a beach for sunbathing or swimming laps. You come for the solitude, for air so clean it stings your sinuses, for the perspective that accompanies standing at the edge of a sea that freezes solid half the year. The nearest convenience store sits five kilometers inland. Cell service flickers. Pack what you need, stay as long as the wind allows, and leave only footprints in that dark, volcanic sand.

Hamakoshimizu Beach is generally not recommended for swimming due to cold water temperatures, strong currents, and lack of lifeguard services. The Sea of Okhotsk can be unpredictable, with powerful waves and undertows even during calm conditions. Most visitors come for scenic walks, photography, and beachcombing rather than water activities. If you do wade in shallow areas, exercise extreme caution and never go alone. The beach is better appreciated for its natural beauty and wildlife viewing opportunities than as a swimming destination.
While accessible year-round, late May through September offers the most comfortable weather for beach visits, with temperatures ranging from 15-25°C. Winter months (January-March) bring unique opportunities to see drift ice from the Sea of Okhotsk washing ashore, creating dramatic landscapes perfect for photography. Summer provides longer daylight hours and clearer skies for enjoying coastal views. Spring and autumn offer fewer crowds and pleasant temperatures for walking. Each season presents distinct scenery, so timing depends on whether you prefer warmer weather or dramatic winter seascapes.
Hamakoshimizu Beach is located in eastern Hokkaido, approximately 45 kilometers from Abashiri. A rental car is highly recommended as public transportation options are limited in this rural area. From Abashiri, take Route 244 east toward Koshimizu town, then follow local signs to the beach. Free parking is typically available near the beach access points. The nearest train station is Koshimizu Station on the JR Senmo Line, but it's still several kilometers from the beach, requiring a taxi or bicycle for the final leg.
Hamakoshimizu Beach has minimal facilities directly on-site, reflecting its remote, unspoiled character. The nearby town of Koshimizu, a short drive away, offers basic amenities including small restaurants serving local seafood, convenience stores, and a few guesthouses or minshuku (family-run inns). For more dining and lodging options, Abashiri (45 km west) provides hotels, izakayas, and seafood restaurants. Visitors should bring water and snacks, as there are no beach vendors. Consider packing a picnic to enjoy while taking in the coastal scenery.
Hamakoshimizu Beach offers excellent birdwatching opportunities, particularly during migration seasons when shorebirds and seabirds pass through eastern Hokkaido. In winter, the beach becomes a prime location for observing drift ice phenomena, occasionally bringing seals along the ice floes. The surrounding coastal meadows and dunes support various wildlife throughout the year. Keep an eye out for white-tailed eagles and Steller's sea eagles in colder months. The beach's low visitor numbers mean wildlife is less disturbed, increasing your chances of meaningful encounters while respecting natural habitats.
