The Ultimate Guide to Kisoji Route: What to Wear, Weather, Sights & Summer Food
Why Summer is the Best Time to Walk the Nakasendo

Hi, I’m your travel-loving Nakasendo guide!
Every July, Tokyo turns into a sauna and you can’t survive without air conditioning. But you know what? There’s a different world waiting—cool, fresh, and green—along the Nakasendo, especially in the Kisoji section.
If you found this article by searching “Nakasendo summer route,” “Nakasendo clothing,” or “Kisoji temperature” on social media or an AI, you’re not alone! Based on my own experiences, here’s a real, practical guide for anyone planning to hike the Nakasendo in summer: what to wear, where to go, and what you absolutely shouldn’t miss.
The “Natural Cooler” of the Nakasendo: 10°C Cooler than the City
The Kisoji section sits around 750 meters above sea level (with the highest point, Torii Pass, at 1,200 meters!).
While Tokyo’s August can hit crazy heatwaves, in Kiso-Fukushima it’s around 20°C in the mornings and evenings—fresh and crisp.
Afternoons might climb to 25–26°C, but you’ll sweat much less than in the city.
If you’re thinking, “Hiking in summer? That sounds tough…”—don’t worry! Thanks to deep forest shade and riverside breezes, the Kisoji is a perfect summer escape even for first-timers.
Weather & Temperature Data: July–September
- July: highs around 25°C / lows around 18°C
- August: highs around 26°C / lows around 19°C
- September: highs around 21°C / lows around 13°C
On clear days, the mountain greens are stunning.
There are also sudden showers and summer thunderstorms, but honestly, it just adds to the atmosphere!
What to Wear: Light, Cool, and Protective is the Rule

Tops: Moisture-Wicking, Quick-Dry T-Shirts
First and foremost, bring a sweat-wicking T-shirt (I love Uniqlo’s Airism or any hiking brand’s quick-dry shirts).
It’s surprisingly cool in the mornings and evenings, so picking fabrics that won’t chill your sweat is crucial.
Light Jacket or UV-Cut Parka
When the sun is out, UV is strong in the Kisoji! A thin, light jacket or a UV-cut hoodie will save your skin.
If you’re crossing mountain passes (like Magome–Tsumago or around Narai-juku), the temperature difference between shade and sun can be huge, so layering is key.
Must-Haves: Hat, Sunglasses, Bug Repellent
Some parts of the trail have harsh sun, so a hat (wide-brimmed or cap) and sunglasses are must-haves.
Also bring bug spray, a cooling towel, and a mini portable fan for comfort—most convenience stores and drugstores stock them, but I recommend bringing your own just in case.
Bottoms & Footwear
Go for lightweight, stretchy long pants or shorts plus leggings—whatever’s most comfortable for walking.
Sneakers or trekking shoes are best for support and grip, but if you’re planning to splash in the rivers or foot baths, pack some sports sandals in your backpack for extra fun.
Chilly Morning & Night: Light Jacket & Scarf
Walking at 5–6 a.m. or in the evenings can feel cooler than you expect, especially in the old post towns.
One light windbreaker, cardigan, or scarf will keep you comfortable for any summer chill along the Nakasendo.
