Mt. Hiuchi Hiking Guide: The Miike Route, Parking and the End of the 2026 Shuttle Season

This guide is based on official information from the Oze Preservation Foundation, Oze Hinoemata Yamatabi (Hinoemata village tourism) and Fukushima Kotsu, checked October 24, 2026. The 2026 Miike–Numayama Pass shuttle bus ends on October 25.

Introduction

Mt. Hiuchi (燧ヶ岳, Hiuchigatake) is the highest peak in the Tōhoku region, at 2,356 m on its main summit, Shibayasugura (柴安嵓). It stands in Oze National Park and is one of Japan's 100 Famous Mountains. The Oze Preservation Foundation rates the route from Miike (御池) on the Fukushima side as difficulty 3: "a long route with some very steep sections, for strong hikers."

This guide focuses on the Miike route, the easiest to do as a day hike, with the access and parking information as of October 2026.

The Miike route (official description)

From the Oze Preservation Foundation's description of the Miike–Mt. Hiuchi route:

• There are boardwalks and steps in places, but also a lot of mud, so wear proper footwear
• Right after Miike the trail turns into a steep, rocky path, and the steep climbing goes on for a while. Take it slowly
• The route climbs the north slope and crosses two marshes, Hirosawa-tashiro (広沢田代) and Kumazawa-tashiro (熊沢田代). From Kumazawa-tashiro, the view of Manaitagura (俎嵓) rising above the marsh is among the best in Oze
• After the marshes the view opens up and the climb eases a little
• Higher up you traverse a slope of loose scree and climb a rough, bouldery gully
• The summit of Manaitagura has a shrine to Hiuchigatake Daigongen, with a view over all of Oze

To reach the main peak, Shibayasugura (2,356 m), you drop to the saddle from Manaitagura and climb back up.

The foundation does not list a distance or time for this route. Plan for a long day and decide your turnaround time before you start.

Access in late October 2026

Miike parking

• Open: April 25 to November 1, 2026, 24 hours a day (Oze Hinoemata Yamatabi)
• Fee: free for the first hour, then ¥1,000 per 24 hours for vehicles up to 2.4 m tall (¥2,000 for taller vehicles)
• ¥10,000, ¥5,000 and ¥2,000 notes are not accepted, so bring ¥1,000 notes
• Miike Lodge, run by the village, has a shop, Yama-no-Eki Miike, with simple meals

Miike–Numayama Pass shuttle bus (for the Lake Oze side)

• The 2026 shuttle's last day is Sunday, October 25. The last bus from Numayama Pass toward Miike leaves at 17:10
• From October 26 to 31 the road between Miike and Numayama Pass is closed for construction, so the shuttle does not run and route buses from the Hinoemata side terminate at Miike (Fukushima Kotsu). Fukushima Kotsu also notes that the 6:30 Hinoemata→Numayama Pass bus and the 17:10 Numayama Pass→Hinoemata bus are cancelled for the whole route during this period
• If it snows before October 25, the shuttle may stop early
• From November the buses switch to a winter timetable

If you just go up and back from Miike, you don't need the shuttle. If you want to combine the climb with the Chōei Shindō trail on the Lake Oze side, you need to finish by October 25.

Season

According to the Oze Preservation Foundation, the 2026 summer opening ceremony for Mt. Hiuchi was July 5. You can climb before the ceremony once the road's winter closure is lifted. October can bring snow, snow cover and ice. Check the latest trail reports before you go, and change your plans if it has snowed. The foundation also warns that frosty boardwalks in the early morning are very slippery.

Clothing and gear

• Proper hiking boots for mud, scree and wet rock
• Rain jacket and pants, a fleece or light insulated layer, a hat and gloves (warm layers are essential in October)
• Plenty of water
• A headlamp, a map app, a mobile battery and a bear bell

Safety points

1. The steep climbs and mud make this a long day even as a day hike. Set your turnaround time first
2. Conditions change quickly in October with snow and ice. Also check the bus suspension and the end of the parking season (November 1)
3. The upper slopes can be windy. Turn back if the weather gets worse

Summary

• The Miike route is difficulty 3 (for strong hikers) from the Oze Preservation Foundation, with steep climbs, mud and scree
• In 2026, Miike parking is open until November 1, and the shuttle runs until October 25 (no service October 26–31)
• There is no official distance or time for the route
• I could not officially confirm the details on hiking registration, toilets, or huts and shelters
