Mt. Bandai (磐梯山, 1,816m) is an active stratovolcano that dominates Fukushima's central landscape, known as 'Aizu-Bandai-san' (会津磐梯山) in regional folk songs celebrating its symmetrical cone shape. The mountain last erupted catastrophically in 1888, when the northern face collapsed, killing 477 people and creating the debris field that formed Lake Inawashiro's surrounding wetlands and the Goshiki-numa colored ponds. The mountain is the centerpiece of Bandai-Asahi National Park, offering multiple hiking routes through alpine meadows, volcanic rock fields, and primeval beech forests.

The most popular summit trail ascends from Happōdai trailhead (5.5km, 3.5 hours ascent), gaining 1,200m elevation through forest zones before emerging above treeline onto volcanic scree. The summit rewards with 360-degree panoramas: Lake Inawashiro to the south, Goshiki-numa ponds to the north, and the distant Japan Alps on clear days. The mountain's dual personality — gentle southern slopes vs. Collapsed northern cliffs — creates dramatic geological contrast visible from the summit. Climbing season runs May–October (snow-free); autumn (September–October) offers peak foliage and clearest skies.

**Trail strategy:** Start early (6:00–7:00am trailhead) to reach summit by 10:00–11:00 when morning clouds clear and afternoon thunderstorms haven't yet formed (common July–August after 14:00). The trail is well-marked with chain assists on steep rocky sections. The 'Ura-Bandai' (裏磐梯, 'back Bandai') views from the collapsed northern crater reveal the 1888 eruption's destruction — a moonscape of broken cliffs and debris flows now colonized by pioneer birch forests. **Autumn optimization:** Late September to mid-October transforms Bandai into a tapestry of reds, oranges, and yellows as deciduous beech forests (1,000–1,400m elevation) reach peak color. The summit above treeline (1,600m+) offers bird's-eye views of the colored slopes below. Book Bandai-Kogen area lodging 2 months ahead for autumn weekends. Photography from the summit is best in morning light (7:00–10:00) when angled sun creates texture on volcanic rock and illuminates distant lakes. **Alternative route:** The Kawagami route (裏磐梯スキー場コース, 6km, 4 hours ascent) ascends the northern collapsed face through the disaster zone — more dramatic geology but steeper and rockier. Experienced hikers can create a traverse: ascend Happōdai (southern route), descend Kawagami (northern route), requiring car shuttle or taxi between trailheads (¥3,000, a drive). This traverse provides the fullest Bandai experience — seeing both the symmetrical 'front' and destroyed 'back' of the volcano.
