Hiratsuka Onsen provides siliceous mineral thermal bathing in the city of Hiratsuka on the Sagami Bay coast of Kanagawa Prefecture, celebrated throughout Japan for its spectacular Tanabata Festival—one of Japan's three great Tanabata celebrations, held every July with elaborate handmade bamboo decorations filling the shopping arcades in a riot of color and craft that draws millions of visitors annually to honor the ancient star festival of Orihime and Hikoboshi. The warm mineral waters of Hiratsuka's onsen provide welcome relief for festival attendees and for the city's residents in a coastal city where Nissan's technical center, light manufacturing, and the Sagami River delta agriculture coexist with beach culture and festival tradition along the Shonan coast. The Oyama shrine on the Tanzawa ridgeline above Hiratsuka and the warm mineral thermal waters together reflect a Kanagawa city of practical industry and vivid seasonal celebration.
