Mount Tanzawa (丹沢山) is a mountain in Kanagawa Prefecture and a central summit of the Tanzawa range, noted for its alpine ridge terrain and established hiking routes. Its summit elevation is 1567 metres.

Hikers follow ridge trails and multi-day routes that link to nearby peaks in the Tanzawa range; clear days offer long-distance views including Mount Fuji. Routes vary from steep single-day ascents to longer traverses that require overnight stays at mountain huts.

The peak is a natural mountain long used for recreation; it is part of the Tanzawa-Oyama Quasi-National Park and has long-standing trail infrastructure rather than a single historic construction. Mountain huts and marked trails have developed to support recreational use.

The mountain sits in western Kanagawa Prefecture within the Tanzawa Mountains, in a forested and rugged landscape northwest of coastal Kanagawa lowlands and within reasonable travel from the greater Tokyo-Yokohama region.

• Elevation: 1567 metres above sea level, making it one of the higher summits in the Tanzawa range.
• Park and access: Located inside the Tanzawa-Oyama Quasi-National Park, with established trail networks and mountain huts on popular routes.

From Shinjuku, take the Odakyu Line to Hon-Atsugi and transfer to local buses toward Yabitsu Pass or other Tanzawa trailheads. Alternatively, drive via Kanagawa Prefectural Route 64 to various parking areas near trail starts.

• Use the Odakyu or local bus services to get to trailheads early in the day; weekday mornings are quietest.
• The trail network connects with the Tanzawa-Ōyama Quasi-National Park-consider looping routes that include waterfalls and ridgelines.
• The Kanagawa side trailheads are steeper; the Yabitsu Passage is the gentlest for long day hikes.
