Overview
Walk a 12 km preserved section of the Tokaido where towering 400‑year‑old cedars shade a road once policed by Tokugawa checkpoints. This full‑day guided hike blends volcanic views of Lake Ashi and Mt. Fuji with stops at a four‑century‑old teahouse and castle ruins.
Hike Hakone Hachiri — Walk the Ancient Tokaido from Odawara to Lake Ashi
Select participants and date
You step off the modern pavement and into a corridor of trees that have seen more travelers than the postcards sold at nearby shrines. The air in Hakone Hachiri is cedar-sweet and cool; the trunks of Cryptomeria japonica rise like old pillars, 400 years of shade stacked along the old Tokaido. Footsteps on the compacted dirt feel like a conversation with history—as you walk, the road narrows, the voices of cars fade, and the landscape opens in fragments: a thatched teahouse tucked by the path, a mirror of Lake Ashi catching Mt. Fuji on a clear day, the grassy shoulder of Yamanaka Castle ruins offering a wind-whipped view over the valley.

Adventure Tips
Hydrate early and often
Carry 1.5–2 L of water—shops are limited on the trail and summer humidity can sap energy quickly.
Sturdy shoes for mixed terrain
Expect packed dirt, stone pavements, and slippery roots after rain—trail runners or mid‑grade boots with good grip work best.
Time your Fuji shot
Start early for the clearest chance of Mt. Fuji views from Yamanaka Castle ruins and soft morning light for photos.
Respect cultural sites
Keep noise low at Amazake Chaya and follow signage—many areas are historic and maintained by local stewards.

History
This stretch of Tokaido was intensively managed under the Tokugawa shogunate—Hakone hosted one of the most heavily policed checkpoints to control travel to Edo.
Conservation
The trail is preserved as a Japan Heritage Area; visitors are asked to stay on marked paths to protect old-growth cedars and archaeological features.
