Insider tip — Seseragi no Shiki, the four seasons of babbling brook, serves Kiso-machi in one of Japan most completely preserved traditional post-road landscapes. The Nakasen-do highway through the Kiso Valley connected Edo to Kyoto through eleven juku post towns whose Edo-period streetscapes at Narai and Kiso-Fukushima remain largely intact — the valley cedar forests, stone paving, and merchant house architecture constituting Japan most authentic inland highway heritage corridor.
