Mt. Haruna & Lake Haruna — Volcanic Crater Lake

**Ropeway & summit views:** The Haruna Ropeway ascends Mt. Haruna-Fuji (1,390m) in 3 minutes (¥840 round-trip). The summit observation deck offers 360-degree views — Lake Haruna directly below, Kanto Plain stretching east, Mt. Akagi (north), and on exceptionally clear days (winter mornings), Mt. Fuji 120km south. The summit has a small shrine and walking paths (10-minute loop). Arrive early morning (9:00-10:00) for clearest views before afternoon haze. **Lake activities:** Rental swan boats (¥800/30 min), rowboats (¥600/30 min), and bicycles (¥500/hour) available at lakeside rental shops. The 4.5km lakeside path is flat, paved, and suitable for casual cycling (60-90 minute loop). Fishing permits (¥500) allow trout and bass fishing. The lake is swimmable but cold (no designated swimming areas). Autumn (late October-November) is peak beauty — maples surrounding the crater turn crimson, reflecting in the lake's still water. **Haruna Shrine approach:** The 700-meter stone path to Haruna Shrine (榛名神社) is one of Gunma's most atmospheric walks — 300-year-old cedar trees, moss-covered stones, seven bridges (each symbolizing stages of spiritual purification), and small waterfalls. The path takes 15-20 minutes, with stone lanterns and torii gates marking the ascent. The main hall is built into the Misugata-iwa rock face — the rock is worshipped as the shrine's shintai (神体, physical embodiment of the deity). Bring a flashlight (forest is dim even midday). **Haruna Shrine combination:** Visiting both Lake Haruna and Haruna Shrine requires a car or taxi (3km distance, buses infrequent). Taxis from Takasaki Station (¥6,000-8,000 one-way) can drop at the shrine, wait while you visit, then continue to the lake (negotiate price beforehand). Or rent a car at Takasaki Station (¥6,000-8,000/day) for full flexibility.
