Mount Buko is the distinctive mountain overlooking the Chichibu basin, easily recognized because one face has been cut away by decades of limestone quarrying, giving it an asymmetrical profile visible from much of the surrounding valley. Despite the industrial scarring on one side, the mountain has established hiking trails to the summit and is treated locally as a shrine mountain, with a sub-shrine near the top. It's a shorter, more accessible climb than many peaks in the wider Chichibu mountains, which is why it draws day hikers rather than only serious climbers.
Mount Bukō is a striking peak overlooking Chichibu, notable for its unusual profile: the mountain's northeast face has been quarried for limestone since the early 20th century, leaving a stepped, terraced scar visible from town that contrasts sharply with the forested southern slopes still open to hikers. The main hiking trail climbs through wooded terrain from the Yokoze Station trailhead to the summit, a round trip of four to six hours depending on pace and conditions, passing shrines and rest points along the way. The summit area offers views over the Chichibu basin and surrounding mountains on clear days. October and November bring the trail's best autumn foliage, when the forested slopes turn shades of red and gold, a striking contrast against the pale quarried rock face visible in the distance. The quarry itself is not part of the hiking route and remains an active industrial site, best viewed and photographed from a distance in Chichibu town or from trail vantage points rather than approached directly. Hikers should start early in the morning given the six-hour upper range of the round trip and the region's limited return bus and train schedules in the evening.
