🌲 ESCAPE THE TOKYO HEAT — MT. MITŌ WATERFALL & THREE PEAKS

東京の暑さを抜け出しお、涌しい枓流・滝・森・山ぞ

━━━━━━━━━━━━━━━━━━━━

ABOUT THIS EVENT / むベントに぀いお

Still hot in Tokyo in September? Let's escape the heat and spend the day in the cool mountain forests of western Tokyo! 🌲💧

While Tokyo can still be hot and humid in early September, the forests of Mt. Mitō offer a refreshing mountain escape, with cool streams, waterfalls, deep beech forests, and mountain air.

Join us for a full-day mountain adventure in Hinohara, following mountain streams to Mitō Great Waterfall, climbing through deep forest, crossing the ridgeline, and reaching the three peaks of Mt. Mitō (1,531 m).

COOL STREAM → WATERFALL → STEEP FOREST TRAIL → RIDGELINE → THREE PEAKS → MOUNTAIN VIEWS 🌲💧⛰
https://www.gotokyo.org/en/spot/527/index.html

We'll begin at Hinohara Tokyo Citizen's Forest and walk through the forest to Mitō Great Waterfall. From there, the route becomes more adventurous as we follow the mountain stream and climb the Ishiyama Trail toward Mt. Ōsawa and Mushi-kari Pass.

We'll then reach Mt. Mitō and explore its three summit peaks — East Peak, Central Peak, and West Peak — before descending through a different forest trail toward Sakaiguchi Pass.

Along the way, we'll experience rushing streams, a beautiful waterfall, mossy forest, beech trees, steep mountain trails, ridgelines, and mountain scenery.
This is not just a hike to reach a summit. It's a chance to escape the heat, cool down beside mountain streams, explore a beautiful forest, challenge ourselves on the trails, meet new people, and experience a completely different side of Tokyo.

Whether you're an experienced hiker, relatively new to hiking, new to Tokyo, visiting Japan, or simply looking for a refreshing summer adventure, you're very welcome to join us!

ただただ暑い9月。東京の暑さを抜け出しお、涌しい山ぞ行きたせんか🌲💧

🌡 A COOL ESCAPE FROM TOKYO / 東京の暑さから逃げよう

Mt. Mitō rises from around 1,000 m to 1,531 m above sea level and is surrounded by dense forest and mountain streams.
The elevation, shade, and flowing water create a much cooler environment than central Tokyo — making this an ideal late-summer escape.

䞉頭山呚蟺は暙高玄1,000mから山頂1,531mの高地にあり、深い森林ず枓流に囲たれおいたす。
暙高、朚陰、そしお枓流の氎によっお、郜心ずは違った涌しい山の環境を楜しむこずができたす。

🥟 DIFFICULTY / 難易床
Moderate / 侭箚

This is a real mountain hike rather than a sightseeing walk.
The route includes several steep uphill and downhill sections, uneven mountain trails, forest paths, and approximately 600–700 m of elevation gain.
You do not need technical climbing experience, but you should be comfortable walking continuously for around 5 hours and handling steep sections.

急な登り・䞋り、凹凞のある登山道、森林の䞭の山道があり、环積暙高差は玄600〜700mです。
特別なクラむミング技術は必芁ありたせんが、5時間皋床歩き続ける䜓力ず、急な登り・䞋りに察応できる䜓力が必芁です。

This is not a race or a fast-paced hike. We'll stay together and enjoy the mountain at a comfortable group pace.

🌲 EXPLORE NATURE TOKYO

We believe the best way to discover a place is not just to visit it, but to walk through it, experience it, and share it with other people.
私たちは、その堎所を知る䞀番の方法は、ただ芳光するこずではなく、実際に歩き、自然を感じ、そしお人ず䞀緒に䜓隓するこずだず考えおいたす。

Waterfalls. Cool streams. Deep forests. Mountain peaks. New friends.
滝、涌しい枓流、深い森、山頂、そしお新しい仲間。

Let's escape the heat, get out of the city, and explore nature together. 🌿💧⛰
