Location	Tokushima Prefecture, Japan

Mount Tsurugi (Japan) is a prominent peak in the Shikoku Mountains on the island of Shikoku, Japan. Rising to about 1,955 meters, it is one of the highest summits in Shikoku and a focal point for regional geography, geology, ecology, and culture. The mountain occupies a key position within Tokushima Prefecture and is a prominent landmark visible from surrounding municipalities and national routes.

Geography and Topography

Mount Tsurugi sits in the central spine of the Shikoku Mountains, near the borders of Mima, Tokushima, Miyoshi, and other Tokushima municipalities. The massif forms part of the drainage divide between basins that feed the Yoshino River and tributaries flowing toward the Pacific Ocean coast. Ridges extend from the main peak to subsidiary summits and cols, connecting to features named in local topographic surveys and maps produced by the Geospatial Information Authority of Japan. The summit area includes rocky outcrops, alpine meadows, and steep escarpments; the mountain is visible from national highways such as National Route 192 (Japan) and passes like the Anan Kaigan Quasi-National Park approaches. Surrounding human settlements include towns and villages historically oriented around forestry, tea cultivation, and mountain transit points documented in prefectural planning.

Geology and Formation

Mount Tsurugi is part of the complex orogenic structure of the Japanese Archipelago shaped by the interaction of the Philippine Sea Plate and the Eurasian Plate along convergent boundaries and associated subduction zones near the Nankai Trough. The bedrock comprises metamorphic and sedimentary units that record Mesozoic to Cenozoic tectonism, regional uplift, and erosional history studied by researchers affiliated with institutions such as the University of Tokyo and regional geological surveys. Structural fabrics, folding, and faulting around the peak reflect the broader tectonic evolution that produced the Shikoku Mountains, with geomorphological processes influenced by Quaternary climate cycles, fluvial incision from the Yoshino River system, and mass-wasting events observed by prefectural hazard assessments.

Climate and Ecology

The climate of Mount Tsurugi is montane, with precipitation patterns influenced by winter monsoon flows and summer typhoon tracks that affect Shikoku and the Seto Inland Sea region. Temperature regimes permit montane vegetation zones including mixed temperate broadleaf forests and subalpine plants; common taxa recorded on slopes and ridgelines have been surveyed by researchers from institutions such as Kyoto University and the Forestry and Forest Products Research Institute (FFPRI). Faunal assemblages include mammals and birds typical of central Shikoku highlands, with conservation attention from prefectural and national bodies including Ministry of the Environment (Japan). Ecological monitoring highlights species of conservation concern and habitats linked to traditional satoyama landscapes managed by local communities and nongovernmental organizations.

Human History and Cultural Significance

Mount Tsurugi holds longstanding cultural and religious significance in regional traditions tied to Shinto and Shugendō mountain worship, with historic practitioners visiting peaks and ridgelines associated with ascetic practices and pilgrimage routes converging on the summit. Local shrines and rites have been connected to Tokushima cultural history recorded by prefectural museums and folklorists. The mountain appears in travelogues and guides compiled during the Edo period and later periods, and it features in modern cultural projects promoted by the prefectural government and tourism bureaus. Land use history includes forestry managed under local cooperative systems, timber transport routes, and postwar infrastructure developments coordinated with agencies such as the Ministry of Land, Infrastructure, Transport and Tourism (Japan).

Recreation and Mountaineering

Mount Tsurugi is a popular destination for hikers, climbers, and nature enthusiasts from across Shikoku and wider Japan, with routes of varying difficulty that access the summit from trailheads served by mountain huts and rest stations. Mountaineering groups affiliated with organizations such as the Japanese Alpine Club and local mountaineering associations maintain trail networks and safety guidance. Seasonal activities include trekking during the summer flower season, autumn foliage viewing, and winter snow hikes requiring alpine equipment; rescue and safety operations are coordinated with Japan Coast Guard-adjacent search services and local volunteer groups. The mountain features in guidebooks produced by publishers in Tokyo and regional outdoor clubs.

Access and Nearby Facilities

Access to Mount Tsurugi is facilitated by prefectural roads, bus services from urban centers like Tokushima and Takamatsu, and parking areas at established trailheads. Accommodation and amenities in nearby towns include minshuku, ryokan, and municipal facilities promoted by the Tokushima tourism office and chamber of commerce organizations. Visitor infrastructure around the mountain—signage, shelters, and interpretive panels—has been developed with participation from the Tokushima Prefectural Government and local community groups to support sustainable tourism and safety for visitors traveling along routes connected to regional rail stations such as those on lines operated by the JR Shikoku network.
