Mt. Nantai Hiking Guide (2026): Climbing Nikko's Sacred Peak from Futarasan Shrine Chūgūshi

Based on Nikko Futarasan Shrine and Nikko Tabi Navi (Nikko City Tourism Association), checked October 24, 2026. The mountain closes on November 11, and you cannot enter it outside the season. Check the latest information before you go.

Introduction

Mt. Nantai (2,486 m) is in Nikko, Tochigi Prefecture. It is one of Japan's 100 Famous Mountains, and the inner shrine (Okumiya) of Nikko Futarasan Shrine stands on its summit. According to Nikko Tabi Navi, the mountain itself has been an object of worship since the 780s. It rises on the north shore of Lake Chūzenji, and the view of it from the lake is one of Nikko's signature scenes.

Key points

1. You can climb only during the season, April 25 – November 11. Reception is at Futarasan Shrine Chūgūshi from 6:00 to 12:00; after noon you cannot start.
2. The fee is 1,000 yen for adults (high school age and up), cash only. Junior high students and younger are free.
3. Allow about 6–8 hours round trip (Nikko Tabi Navi average: about 7 hours). The climb is about 1,200 m, with no water or toilets on the way.

Basic information

Why it is popular

• One of the 100 Famous Mountains and a symbol of Nikko
• The summit has the shrine's inner sanctuary, so you can feel its long history of mountain worship
• From the top you get a panorama of Lake Chūzenji and distant peaks (Nikko Tabi Navi)

But "doable in a day" does not mean "easy". Nikko Tabi Navi also notes that there are steep rocky sections.

The route

The standard route is out and back from Futarasan Shrine Chūgūshi. Nikko Tabi Navi gives about 6–8 hours round trip, about 8 km, and about 1,200 m of ascent. You pay the climbing fee (hatsuhoryō, an offering) of 1,000 yen at reception before starting.

How the climb works

1. Register at Futarasan Shrine Chūgūshi and pay the fee (the gate opens at 6:00 every morning; reception until noon)
2. Start up the trail. There is no water and no toilet on the way
3. At the summit you can visit the inner shrine
4. Return the same way

The shrine asks hikers to come down before sunset, while it is still light. Even if you register before noon, plan your time so you are down before dark. With an average of about 7 hours, avoid late starts. The days are short in late October and early November.

During the Nantai-san Tohai Festival, held for a week from July 31 every year, the gate opens at midnight so climbers can see the sunrise from the summit (Futarasan Shrine).

Access

Train and bus

According to Nikko Tabi Navi, take a bus bound for Yumoto Onsen from JR Nikkō or Tōbu-Nikkō Station for about 55 minutes and get off at "Futarasan-jinja Chūgūshi"; the trailhead is right there. Check fares, the number of buses, and the last bus in Tōbu Bus Nikko's latest timetable.

Car

About 25 minutes from Kiyotaki IC (Nikko Tabi Navi). For the Okunikko prefectural car parks, see the Tochigi Prefecture website. We could not confirm the official fee for the shrine's car park.

Best season

Nikko Tabi Navi says June to October is the best time to climb. Summer is cool, autumn has colorful leaves, and in winter it turns into a harsh snowy mountain.

• The season is April 25 – November 11. You cannot enter before or after.
• We could not confirm official information on lingering snow in late April to early June or on cold in November. At those times, ask the shrine about current conditions.

Cautions

No water or toilets

The shrine says: "about 6–7 hours round trip; there is no water or toilet on the way. Do not forget a light and a bear bell." Bring enough water from the trailhead.

Steep climb and rocks

The ascent is about 1,200 m, and there are steep rocky sections. Wear hiking boots with good grip and watch your footing on the way down.
