Image d'illustration — il ne s'agit pas d'une photo de ce lieu.

Le lac Ashi occupe le cratere d'une eruption volcanique vieille de 3 000 ans, au coeur de Hakone, et par temps clair, il reflete la silhouette enneigee du mont Fuji dans ses eaux. Les bateaux pirates de la compagnie Hakone proposent une croisiere panoramique de 30 minutes entre Togendai et Moto-Hakone, passant pres du torii rouge du sanctuaire de Hakone qui emerge de l'eau.

Hakone est l'escapade thermale la plus accessible depuis Tokyo (1,5 heure en train), et le lac Ashi se combine aisement avec le telepherique d'Owakudani (fumerolles et oeufs noirs), les musees d'art en plein air et les ryokan avec onsen prive. Le Hakone Free Pass couvre tous les transports de la region.

Hakone-Yumoto Station (Odakyu Hakone Line) as hub, then bus or ropeway | Togendai (Hakone Ropeway terminus) or Moto-Hakone (bus stop) for lake access

Temps de trajet

From Shinjuku: ~85–90 min to Hakone-Yumoto by Odakyu, then ~40 min bus to lake | From Tokyo Station: ~100 min via Shinjuku | From Osaka: ~3 hours by Shinkansen to Odawara, then bus

Comment y aller

Train + Bus (recommended): Odakyu Romance Car from Shinjuku to Hakone-Yumoto (¥2,330, ~85 min), then Hakone Tozan Bus to Moto-Hakone or Togendai (~40 min). Hakone Freepass: ¥6,100 for 2 days — covers round-trip Romance Car + unlimited Hakone buses, ropeway, cable car, and pirate ship. Excellent value for any full-day visit. Car: Tokyo via Tomei Expressway to Atsugi IC, then Route 246 and Route 1 into Hakone (~90 min, tolls ~¥1,500). Parking at Togendai and Moto-Hakone (¥600–800/hour). Roads can be congested on holiday weekends.

Meilleur moment pour visiter

Weekdays 9:00–10:00 AM for morning mist photography before tour groups arrive. Winter mornings (7:00–9:00 AM) offer the best chance of clear Mt. Fuji views. The first pirate ship of the day (9:30 AM from Togendai) is least crowded.

Conseils pour éviter la foule

Peak congestion: Golden Week (late April–early May) and autumn leaf season (mid–late November). Arrive before 9:30 AM on weekends to beat tour buses. The east shore hiking trail (4 km, near Old Tokaido Road) is almost always uncrowded regardless of season.

Informations de stationnement

Togendai: free parking lot (~200 spaces, fills by 10 AM on weekends). Moto-Hakone: roadside paid parking ¥600–800/hour. Hakone-machi: paid lot near the checkpoint (¥500/hour). Train and bus is strongly recommended on holiday weekends to avoid traffic jams on Route 1.

Guide d'initié

**Reading Fuji conditions:** The webcams lie. Hotel websites and ropeway feeds show wide-angle shots that compress distance and make Fuji look present when it's actually a grey smudge. Better method: check the Japan Meteorological Agency's visibility forecast for the Hakone area and look for readings above 30km — that's your threshold for a clean Fuji view. Winter mornings (December-February) between 6:30-8:30am deliver the sharpest outlines, when cold air settles and the sun backlights the snowcap without creating haze. By 11am even clear days tend to soften as humidity rises off the lake. Summer visitors (June-August) are chasing a 10% probability. Rainy season dumps clouds across the caldera for weeks straight, and even the brief clear windows come with afternoon haze that turns Fuji into a ghost outline. If you're here summer and Fuji shows up, photograph immediately — the mountain can vanish in 20 minutes when marine layer rolls in from Suruga Bay. Typhoon aftermaths (September-October) occasionally gift you 24-hour windows of crystal air when Fuji looks close enough to touch, but you can't schedule around typhoons. **Pirate ship deck tactics:** The ships carry 500+ passengers but only the upper deck delivers unobstructed photos — the lower cabin has windows blocked by bench seating and internal reflections that ruin shots. Boats depart Togendai hourly starting 9:30am, with the first departure seeing maybe 40 people while the 10:30am run packs 300. If Fuji is visible, position yourself on the stern (rear deck) facing south 15 minutes before departure — that's where you'll have clean sightlines without railings cutting through the frame. Port-side (left when facing forward northbound, right when southbound) gives you the broadest Fuji view on the Togendai-to-Moto-Hakone run. Bring something for wind: even July crossings can hit 15-knot gusts once you clear the Moto-Hakone breakwater, and winter wind-chill drops the effective temperature 8-10 degrees below shore readings. The crossing takes 25 minutes at 18km/h cruising speed. The captains cut engines and drift for 2-3 minutes at the midpoint if Fuji is out — your cue to shoot before the diesel vibration resumes. **Torii and shrine circuit timing:** The red torii standing in the shallows belongs to Hakone Shrine, planted there in 1952 during post-war reconstruction. It sits 50 meters offshore in water that averages 1.5m deep at the gate's base. The classic shot — torii in foreground, Fuji beyond — requires a 70-200mm lens to compress the 25km distance into a single plane. Shoot from the eastern shore path between 7:30-9:00am when the gate receives front light and Fuji emerges from dawn mist. Crowd pressure starts building at 9:30am when the first tour buses disgorge groups. By 11am you're sharing the 3-meter-wide path with 200+ people, all angling for the same shot, and the water surface loses its morning glassiness to boat wake and wind chop. Weekday winter mornings see maybe a dozen other photographers; weekend summer afternoons can mean a 15-minute wait just to reach the optimal shooting position. After you've shot the torii, walk inland 5 minutes through the cedar forest to the main shrine — the trees are 600-800 years old, trunks reaching 3+ meters in circumference, and the canopy filters light into green-gold shafts that hit differently than the lakeside glare. **Alternative lake access points:** Most visitors never leave the three main ports, but the eastern shore has a hiking trail (part of the old Tokaido Road) that parallels the water for 4km between Moto-Hakone and Kojiri. The path stays in forest shade, dipping occasionally to rocky beaches where you can crouch at water level and shoot straight across the lake toward Mt. Komagatake's ridgeline. You'll encounter maybe 5 other hikers on a weekday morning, and the silence is complete except for water lapping stones and occasional boat engines in the distance. No facilities, no vendors, just caldera and forest. The trail requires 90 minutes one-way at moderate pace, with 200m cumulative elevation change as it climbs over headlands. Some sections follow original Edo-period stone paving — cobbles worn smooth by 400 years of foot traffic. This is where you actually feel the caldera's scale, the way the water fills space between mountains, rather than just photographing it from a crowded viewpoint.
