GUNUNG · Jepang

Akadake (Gunung Aka, Yatsugatake)

赤岳 (Akadake)

Information

Elevation: 2.899 m
Country: Jepang (JP)
Location / Range: Rangkaian Yatsugatake (八ヶ岳連峰) — perbatasan Prefektur Nagano (Chino & Hara) dan Yamanashi (Hokuto), Honshu
Mountain type: Puncak tertinggi gugusan gunung berapi Yatsugatake (bagian Yatsugatake selatan / Minami-Yatsugatake) — puncak batuan vulkanik terkikis
Volcanic?: Yes — volcano
Coordinates: 35.9706, 138.3700
Difficulty: Sulit–menengah (hiking alpine dengan scrambling): pendakian sehari yang populer namun menuntut kebugaran, dengan tanjakan berbatu curam dan segmen rantai serta tangga besi di punggungan menuju puncak. Punggungan Yatsugatake selatan (Yokodake–Iōdake) menuntut kehati-hatian karena eksposur; versi musim dingin bersalju hanya untuk pendaki beralat dan berpengalaman.
Best Season: Rencanakan berdasarkan kondisi salju, prakiraan cuaca, serta jadwal pondok terkini; laporan musim panas juga mencatat hujan dan badai.
Permits & Rules: Periksa ketentuan akses dan reservasi langsung dengan pengelola pondok sebelum berangkat; laporan perjalanan bukan bukti aturan izin terkini.
Hazards: Scrambling berbatu terbuka dengan rantai dan tangga besi di dekat puncak, risiko jatuh dan batu longsor, cuaca gunung yang cepat berubah dan kabut, badai petir sore di musim panas, serta salju dan es di musim dingin yang menuntut peralatan alpine. Punggungan berbatu Yokodake yang tajam menuntut perhatian ekstra.

Description

Akadake (2,899 m) is the highest summit of Japan’s Yatsugatake range, on the Nagano–Yamanashi border. The western approach through Minoto links wooded valleys to Gyōja-goya and rocky summit ridges. The Jizō and Bunzaburo trails include ladders and chain-assisted sections. First-hand accounts show how hut stays can support an itinerary while changing weather can still force plans to change.

Scrambling berbatu / Rocky scrambling

9 jam dalam catatan penulis / 9 hours in the author’s log

An extension via Jizō Ridge to Akadake, Nakadake and Amidadake, returning through Nakadake col and Gyōja-goya. The author started at 05:00 and returned at 14:00; that timing is not a benchmark for every hiker.

Sulit–menengah — hiking alpine dengan scrambling berbatu dan segmen rantai/tangga besi di punggungan atas

Bisa bermalam; sesuaikan jadwal dengan cuaca / Hut itinerary; allow for weather delays

From Minotoguchi, follow Minoto and Minamisawa to Gyōja-goya, then climb Jizō Ridge to Tenbou-so and the summit. The 100 Peaks account records a storm delay before descending Bunzaburo; it is a historical itinerary, not a standard timing estimate.

Climbing Experiences

These videos and field accounts cover day hikes, hut trips and winter attempts on Akadake. Three added reports document waiting out a storm in a hut, a rainy Bunzaburo ascent and a link to Amidadake. Reported conditions are historical observations, not a current trail bulletin.
