Mt. Echigo-Komagatake (越後駒ヶ岳, 2,003 m) in Uonuma City, Niigata Prefecture, is the principal peak of the Echigo Sanzan (Echigo-Komagatake, Naka-no-dake, Hakkai-san) within Echigo Sanzan Tadami Quasi-National Park — a 100 Famous Mountain of Japan (Kyūya Fukada’s selection).
Also known as “Uonuma Komagatake“, this majestic free-standing peak is best reached via the Shiori-toge course (standard, most popular), a long ridge walk through Michiyukiyama and Ogura-yama with an overnight option at Koma-no-koya (unstaffed emergency hut below the summit), intermediate ★★★ / ~9 h round trip. Famous for the “flowing-cloud waterfall” (taki-gumo) phenomenon at dawn and the yellow-daylily fields in summer / autumn colours.

2. [Round trip] Koide Station ⇔ Shiori-toge (Minami Echigo Kanko Bus, summer 1 run/day)
For the Shiori-toge course trailhead at Shiori-toge (1,065 m), the Minami Echigo Kanko Bus (Koide Station → Oyu Onsen → Ginzandaira → Shiori-toge) takes about 1 h 5 min / ¥680 / only 1 run per day in summer (typically late June – October). Because of this limit, Ginzandaira Campsite or Koma-no-yu Onsen pre-night is the standard plan. The “Uonuma Taki-gumo Shuttle Bus” (typically late September – early November weekends/holidays) eases congestion. Self-drive: ~1 h from Kan’etsu Expressway Koide IC via Okutadami Silver Line; Shiori-toge parking ~30 spaces, free (full in peak autumn).
Operating period : Typically late June – October (summer climbing season only)
Travel time : Koide Station → Shiori-toge about 1 h 5 min
Fare : ¥680 (one way)
Frequency : 1 run/day (summer regular) + Taki-gumo Shuttle on weekends/holidays (late Sep – early Nov)
Koide Station → Shiori-toge (Minami Echigo Kanko Bus, summer 1 run/day, hiker excerpt)
| Koide Station dep. | Oyu Onsen via | Shiori-toge arr. |
|---|---|---|
| around 6:30 (summer regular, confirm) | around 6:55 | around 7:35 |
| ※ Taki-gumo Shuttle (Sep–Nov weekends/holidays) has earlier services |
Shiori-toge → Koide Station (Minami Echigo Kanko Bus, return, summer 1 run/day)
| Shiori-toge dep. | Oyu Onsen via | Koide Station arr. |
|---|---|---|
| around 15:30 (summer regular, last) | around 16:10 | around 16:35 |
Note : Operating periods and times vary by year — always confirm with Minami Echigo Kanko Bus or Uonuma City Tourism. With only 1 daily run, a same-day return is tight (arrive 7:35, last bus 15:30 = ~8 hours), so the 9-hour course is hard. Overnight at Ginzandaira / Koma-no-yu Onsen with early-morning self-drive or minshuku transfer is realistic. After descending, bathe at “Koma-no-yu Sanso” (secluded onsen, ~¥600).

About Mt. Echigo-Komagatake
The principal peak (2,003 m) of the Echigo Sanzan (Echigo-Komagatake, Naka-no-dake, Hakkai-san) in Uonuma City, Niigata, within Echigo Sanzan Tadami Quasi-National Park. Locally called “Uonuma Komagatake” to distinguish it from other Komagatake in Japan (Kiso, Kai, Aizu, etc.). Selected by Fukada as one of his 100 Famous Mountains, this majestic free-standing peak is famous for the “taki-gumo” (flowing-cloud waterfall) at dawn — clouds streaming down the ridge in September – October — and is popular among photographers.
