Kisoji — A Highway Stroll in Nagano Where Nakasendo Post Towns Remain

Lattice-fronted townhouses lining stone-paved slopes, the traces of inns at the masugata bends, and the old highway threading deep mountains. The Kisoji is a section of the Nakasendo running north to south along the Kiso River through southwestern Nagano. Along this road that once linked Edo and Kyoto lie post towns that preserve their old appearance, such as Narai, Tsumago, and Magome. Walking the townscapes that feel like a time slip, you can savor the mood of travelers of old, on a popular highway stroll.

Highlights

Along the Kisoji lie Nakasendo post towns surrounded by deep mountains. Foremost among them is Narai-juku. As the 34th of the Nakasendo's sixty-nine stations, it conveys to this day the prosperity once praised as Narai of a thousand houses. The townscape, where lattice-fronted houses line up for about one kilometer, is known as one of Japan's longest post towns and was designated a national Important Preservation District for Groups of Traditional Buildings in 1978. Buildings with overhanging upper floors, water basins, and temples and shrines remain along the highway, spreading a scene that feels like a time slip to the Edo period.

Enjoying the Seasons

Spring greenery (April to May) and autumn foliage (October to November) are especially beautiful and ideal for strolling the post towns. In summer the cool mountain air is pleasant, and in winter the snow-dressed townscape shows a dreamlike charm. At Narai-juku the Kiso Lacquerware and Narai Post Town Festival is held around June each year, drawing large crowds. The pass-crossing hike linking Tsumago and Magome is especially popular in the fresh-green and autumn seasons. Enjoying each season's expression, you can feel the air of the old highway.

Access and Basic Information

• Location: southwestern Nagano Prefecture (Shiojiri City, Kiso Town, Nagiso Town, and others)
• Narai-juku: right by Narai Station on the JR Chuo Main Line
• Tsumago-juku: bus from Nagiso Station on the JR Chuo Main Line
• Magome-juku: hike from Tsumago-juku, or bus from Nakatsugawa Station

Practical Travel Notes

At Narai-juku the townscape spreads right off the station, and a stroll takes about one to two hours as a guide. The pass-crossing hike from Tsumago to Magome (about 8 km) takes roughly two to three hours one way. On some sections a baggage-forwarding service carries luggage between post towns, letting you walk light. Prepare sturdy shoes and water, and take care as the pass path is slippery in rain. The post towns have eateries, souvenir shops, and inns making use of traditional lodgings, and staying overnight lets you savor the quiet townscape morning and evening. A budget from the low thousands per person for food and souvenirs if focused on strolling, or several thousand yen if adding lodging or hiking, is a guide.

One Piece of Advice

The Kisoji post towns each have their own character. Combining several, such as Narai as one of Japan's longest, Tsumago which took up landscape preservation early, and Magome with its stone-paved slopes, lets you feel the appeal more deeply. In comfortable walking shoes, enjoy a journey through time touring the Kisoji post towns.
