Sagamihara: Miyagase Dam
Tucked into the wooded foothills of the Tanzawa Mountains, Miyagase Dam is a place whose character is shaped by the Nakatsu River. Completed in 2000, the 156-metre concrete arch dam impounds Miyagase Lake and forms part of the water-management system for the Sagami River basin. Its broad curved wall stands between steep forested slopes, where major infrastructure meets a mountain catchment. The dam has flood-control and water-supply roles, while the reservoir has transformed a former river valley into an inland destination within Kanagawa Prefecture. This is a markedly different side of the region from the densely developed coastal plain around Yokohama and Kawasaki.

Built across the Sagamihara Plateau beside the Sagami River, Sagamihara grew into an ordinance-designated city on Tokyo’s western fringe. Its extensive municipal area leads from dense railway suburbs in the east towards Lake Sagami, a reservoir formed by the Sagami Dam, and the wooded foothills of the Tanzawa Mountains. The city also plays a role in Japanese space science: JAXA’s Sagamihara Campus is home to the Institute of Space and Astronautical Science. Rivers, reservoirs and mountain roads give western Kanagawa a markedly different character from the capital’s urban core.

Sagami Bay and the foothills of the Tanzawa Mountains shape much of Kanagawa Prefecture — the coast supports port cities and seaside communities, while the interior rises toward forested uplands. Yokohama, the prefectural capital, developed into a major international port after opening to foreign trade in 1859; its waterfront remains central to the city’s identity. To the west, Hakone brings volcanic terrain and hot springs, while Kamakura preserves important Buddhist temples and the Great Buddha at Kōtoku-in. Along the Shōnan coast near Fujisawa, beaches and Enoshima link daily life closely to the sea. Continue through nearby webcams to explore different parts of Kanagawa Prefecture.

Among the countries of East Asia, Japan stands out for its volcanic archipelago, stretching from the cool north of Hokkaido to subtropical Okinawa. Mount Fuji, the nation’s highest mountain, rises above central Honshu, while the Pacific Ocean and the Seto Inland Sea have long shaped settlement, fishing and travel. Tokyo pairs dense urban life with major museums and neighbourhood traditions; Kyoto preserves temples, gardens and the legacy of Japan’s imperial court. Seasonal customs give journeys a changing rhythm, from spring cherry blossom viewing to autumn leaves. Regional cooking is equally varied, with sushi, ramen and local specialties reflecting coastlines, climate and agriculture.
