Minamiboso

Minamiboso is an administrative division in the southern part of Boso Peninsula within Chiba Prefecture, encompassing coastline, beaches and forested hills. The city area extends from the Pacific shore to gentle mountains inland, with several fishing villages and farming valleys.

The territory belonged to Awa Province during feudal times and remained under Satomi clan control through the 16th century. The modern city administration formed in 2006 by merging six towns along the coast.

Residents often speak of the local tradition of harvesting wakame seaweed along the coast, a practice still visible in small harbors today. Fishers sell their catch directly at the quayside each morning while farmers offer loquats and other fruit at small roadside stands.

Travelers reach the area via the Uchibō railway line or by ferry across Tokyo Bay, with driving along coastal roads offering the best access to individual villages. Seasons influence both weather and local activities, with summer bringing warm days at the beaches.

The warm ocean current offshore allows coral to grow at some underwater sites, unusually far north for such lifeforms. Local divers sometimes show visitors these unexpected reef sections during warmer months.
