Kiso-Fukushima & Fukushima-juku: A Beautiful Historic Post Town in Japan

27 June 2025

Visiting Kiso-Fukushima is a chance to walk on the same stone paths that samurai warriors used 400 years ago, surrounded by beautiful mountains at 1,000 metres above sea level. This special place offers you a real conversation with Japanese history.

Kiso-Fukushima's charm is truly unique. You can enjoy amazing mountain views, beginner-friendly hiking on the historic Nakasendo Trail (中山道), and 400-year-old streets from Japan's Edo period (江戸時代, 1603-1868). The best part is that you can explore all of these attractions on foot within a small area. It's perfect for visitors who want to enjoy nature whilst learning about Japanese history and culture. From Kiso-Fukushima, you can also easily reach famous historic towns like Tsumago-juku (妻籠宿) and Magome-juku (馬籠宿).

The Historical Importance of Fukushima-juku (福島宿)

Fukushima-juku was located almost halfway along the Nakasendo Trail. This trail connected Edo (江戸, old Tokyo) and Kyoto (京都), and Fukushima-juku was an important resting place for travellers. The town had one of Japan's four major checkpoints called "Fukushima Sekisho" (福島関所), making it the political, economic, and transport centre of the Kiso Valley (木曽谷).

The Nakasendo Trail and the Post Town System

To understand Fukushima-juku, we need to learn about the Nakasendo Trail (中山道). This was one of five major roads built during Japan's Edo period. It connected present-day Tokyo and Kyoto over about 540 kilometres. Along this road, there were 69 post towns (宿場町) that provided accommodation, food, and fresh horses for travellers.

Fukushima-juku was extremely important as both a post town on the Nakasendo and the gateway to the Kiso Valley. The area was rich in forest resources, so the Edo government (江戸幕府) controlled it directly as "tenryo" (天領, government land).

The Role of Fukushima Checkpoint

The most important feature of Fukushima-juku was the Fukushima Sekisho (福島関所). This checkpoint enforced the government's policy of "iri-deppo ni de-onna" (入り鉄砲に出女), which meant:

Iri-deppo (入り鉄砲): Stopping weapons from entering Edo
De-onna (出女): Stopping the wives of feudal lords from leaving Edo (this was part of a hostage system)

This strict checkpoint system made Fukushima Sekisho as important as the famous Hakone Sekisho (箱根関所) for the government's security.
