🍒 Mt. Takao — Trail 6 + Inariyama Ridge Return

Why Trail 6 and not Trail 1

  • Trail 1 is paved and crowded — Trail 6 is rocky, natural, and far more interesting
  • Follows a boulder-strewn streambed, past Biwa Falls (meditation waterfall), cave shrine mid-route
  • Cherry blossoms at Itchodaira (beyond the summit) peak mid-to-late April — 2 weeks after central Tokyo

Distance: ~9–10 km loop Elevation Gain: ~480 m (summit 599 m) Difficulty: Moderate Time: 4–5 hours

Transit from Ikebukuro: Yamanote/Shonan-Shinjuku → Shinjuku → Keio Line Limited Express → Takaosanguchi Station ~60–65 min / ~¥430 from Shinjuku

What to see:

  • Biwa Falls (ascetic waterfall site on Trail 6)
  • Iwaya Daishi cave shrine mid-route
  • Summit: Tokyo skyline views east, Fuji views west on clear days
  • Itchodaira area: late April cherry blossoms

Extension: Continue west to Kobotoke-Shiroyama (670 m) and Jinba-san — see traverse below

🏔️ Takao to Jinba Traverse — Best Full Day Near Tokyo

Why this is the recommended full-day objective

  • 15 km ridge crossing four peaks: Takao (599m), Kobotoke-Shiroyama (670m), Kagenobu-yama (671m), Jinba-san (855m)
  • Jinba-san summit: famous white horse statue, panoramic views including Fuji on clear days
  • Point-to-point via two different train lines — no retracing

Distance: ~15.3 km one-way Elevation Gain: ~700 m cumulative (significant up-and-down on ridge) Difficulty: Moderate–Hard Time: 7–8 hours

Transit: Start: Keio Line → Takaosanguchi Station (from Ikebukuro, ~65 min) End: JR Chuo Line → Fujino or Sagamiko Station back to Shinjuku/Tokyo

🌸 Mitakesan + Odakesan — Mountain Village + Wilderness

Why it’s unique

  • Summit has a functioning mountain village: Musashi-Mitake Shrine, lodge-hotels, cafés
  • Rock Garden (Nantai-en) between the two peaks — one of the finest boulder-stream landscapes near Tokyo
  • April wildflowers (Oorurikusa — blue wildflowers) carpet the Rock Garden area
  • Full traverse to Okutama Station through deep cedar forest for point-to-point logistics

Distance: ~12 km (Mitakesan + Odakesan + descent to Okutama Station) Elevation Gain: ~860 m total; cable car option reduces gain to ~400 m Difficulty: Moderate (with cable car) to Hard (full ascent) Time: 5–7 hours

Transit from Ikebukuro: JR Chuo Line → Tachikawa (~28 min, ~¥484) → JR Ome Line → Mitake Station (~50 min, ~¥660) → Bus to cablecar base (~10 min, ~¥340) → Cablecar to summit (~¥1,130 round trip) Total: ~90–100 min

🏞️ Hatonosu Valley — Okutama Gorge (Easier Option)

Why it works as a lighter day

  • Dramatic river gorge scenery — suspension bridges, carved rock faces, narrow gorge sections
  • Good option if wanting Okutama-area without the Odakesan full commitment
  • Can combine with Mitakesan in the same day (both on the Ome Line)

Distance: ~6 km loop Elevation Gain: ~545 m Difficulty: Moderate Time: ~3.5 hours

Transit from Ikebukuro: JR Chuo Line → Tachikawa → JR Ome Line → Hatonosu Station ~80 min / ~¥990

💪 Tonodake (Tanzawa) — Most Demanding Day Hike from Tokyo

Why it’s the serious option

  • Highest elevation day hike realistically accessible from Tokyo (1,491 m summit)
  • The ascent trail is nicknamed “baka-one” (stupid ridge) — relentless wooden staircase
  • Open grassy summit with 360° views: Fuji to the west, Sagami Bay to the south
  • Mountain hut at summit (Hina-goya) serves food and drinks
  • Extension to Mt. Tanzawa (1,567 m) adds 30–40 min of wilder ridge

Distance: ~13.8 km round trip Elevation Gain: ~1,200 m Difficulty: Strenuous — the hardest hike on this list Time: 7–8 hours minimum

Transit from Ikebukuro: Yamanote → Shinjuku → Odakyu Line → Shibusawa Station (~70 min, ~¥860) → Bus to Okura Bus Stop (~15 min) First bus departs Hadano early — check current timetable Total: ~100 min

April note: April is one of the last good months before summer — Tanzawa leeches are not yet active (they arrive June–September).

April Conditions

  • Mt. Takao: Trail 6 natural and uncrowded vs. Trail 1 crowds; Itchodaira cherry blossoms mid-to-late April
  • Mitakesan: Rock Garden blue wildflowers bloom in April — timing is ideal
  • Tanzawa: April is the window before summer leech season — go now or wait until November
  • Jinba traverse: spring greenery excellent; Fuji visibility better in November but April is fine
  • All routes: pack layers — summit temps noticeably cooler than Tokyo
