Mt. Kurikoma Hiking Report: Ascending the Higashi-Kurikoma Stream Trail & Descending the Chuo Course from Iwakagamidaira

On Tuesday, July 28, 2026, I hiked Mt. Kurikoma (栗駒山, elevation 1,626 m)—one of the 200 Famous Japanese Mountains (日本二百名山) straddling the borders of Miyagi, Iwate, and Akita Prefectures—on a clockwise loop from Iwakagamidaira (いわかがみ平, ~1,113 m) on the Miyagi side.

Ascending the Higashi-Kurikoma Course (東栗駒コース), where part of the trail climbs directly up a shallow bedrock mountain stream, and returning down the well-maintained stone-paved Chuo Course (中央コース), I completed the 6.5 km loop in exactly 3 hours (6:07–9:07) despite thick summer fog on the upper ridge. Here is a full breakdown of trail conditions, waterproof footwear requirements, seasonal traffic rules, and hot springs around the mountain.

Why Climb via the Higashi-Kurikoma Course and Descend via the Chuo Course?

From the Iwakagamidaira trailhead on the Miyagi side, two main trails lead to the summit of Mt. Kurikoma:

1. Chuo Course (中央コース, approx. 3.0 km one way): A wide, gentle path paved with flat stone slabs and concrete blocks for the lower two-thirds, switching to gravel and rock steps near the summit.
2. Higashi-Kurikoma Course (東栗駒コース, approx. 3.5 km one way): A more varied mountain trail that crosses open bedrock stream channels (渡渉・沢登り区間), climbs fixed-rope gullies, and traverses an exposed ridge over Mt. Higashi-Kurikoma (東栗駒山, ~1,430 m) before joining the main peak.

If you plan to combine both into a loop, ascending the Higashi-Kurikoma Course and descending the Chuo Course (clockwise) is strongly recommended:

• Stepping across wet rocks and climbing the shallow stream bed on the Higashi-Kurikoma Course is much safer and easier to judge on the way up than when descending on tired legs.
• Descending via the well-graded stone pavement of the Chuo Course lets you return quickly and safely even if afternoon clouds or drizzle roll in.

Trail Report

1. Iwakagamidaira Trailhead & Ascending the Higashi-Kurikoma Stream Bed

I arrived at the Iwakagamidaira (いわかがみ平) parking lot shortly before 6:00 AM. Located at around 1,113 m elevation, the lot has free parking and public restrooms at the Iwakagamidaira Rest House, putting you more than two-thirds of the way up the mountain's vertical height before you take a single step.

Setting off at 6:07 AM on the Higashi-Kurikoma Course, the trail initially winds through dense shrub forest pinched tightly by waist-high vegetation. Because of deep mud and puddles along the sunken path, keeping your footing on the stones takes constant attention from the start.

Roughly halfway to Mt. Higashi-Kurikoma, the trail enters the Shin-zawa (新沢) stream crossing and bedrock watercourse section. Here, the hiking path and a shallow mountain stream become one and the same: you step from slab to slab while ankle-deep water runs around your boots.

• Waterproof high- or mid-cut hiking boots (such as GORE-TEX boots) are essential on this route; non-waterproof trail running shoes or low-cut sneakers will soak through immediately.
• Warning after heavy rain: Because the trail follows an active drainage channel, water volume rises rapidly during or right after heavy rain, submerging stepping stones and turning the route hazardous. If heavy rain is forecast or has just fallen, skip the Higashi-Kurikoma Course and use the Chuo Course round-trip instead.

2. Emerging onto the Windy Ridge at Mt. Higashi-Kurikoma

Exiting the stream bed, the trees suddenly drop away to reveal an open alpine slope—normally one of the most scenic viewpoints on Mt. Kurikoma, though wrapped in dense white fog on this morning.

At 7:13 AM (1 hour 6 minutes from the trailhead), I reached the junction peak of Mt. Higashi-Kurikoma (東栗駒山, ~1,430 m). Without trees to block the wind, the breeze across the open ridge felt noticeably chilly even in late July—a reminder to keep a windproof shell or rain jacket accessible at the top of your pack.

After a 3-minute breather, I followed the gently rolling ridge trail west-northwest toward the main summit. Even through the mist, alpine summer blooms and lush green meadows lined both sides of the path, hinting at why Mt. Kurikoma's autumn foliage—known as "Kami no Jutan" (神の絨毯, the "Carpet of the Gods")—is considered among the finest in Japan.

3. Mt. Kurikoma Summit (1,626 m) & Descending the Chuo Course

Climbing the final flight of steps where the Higashi-Kurikoma trail merges with the Chuo Course, I stood on the broad summit plaza of Mt. Kurikoma (1,626 m) at 8:04 AM—1 hour 57 minutes after leaving Iwakagamidaira.

After a brief 4-minute stop at the windy summit (08:04–08:08), I began descending the Chuo Course (中央コース). The upper section descends wide gravel and rock steps, then transitions into a smooth, stone-paved promenade running straight down through low alpine scrub to Iwakagamidaira.

Even when wet with mist, the stone pavement offered predictable footing, allowing a steady 59-minute descent back to the Iwakagamidaira parking lot by 9:07 AM.

Trailhead Access, Seasonal Road Closures & Autumn Shuttle Rules

1. Driving to Iwakagamidaira (いわかがみ平)

• Route: Approximately 70 minutes by car (around 42 km) from Tsukidate IC (築館IC) or Wakayanagi-Kannari IC (若柳金成IC) on the Tohoku Expressway via Prefectural Route 42 (the Kurikoma Mountain Road).
• Parking & Restrooms: Free parking (~120 regular spaces outside peak foliage regulation periods) and flushing restrooms are available at Iwakagamidaira (Kurihara City Official Tourism Portal — Iwakagamidaira).
• Public Transit Note: There is no regular year-round route bus to Iwakagamidaira from Kurikoma-Kogen Shinkansen Station or Ishikoshi Station; outside limited autumn sightseeing bus dates, access requires a rental car or taxi.

2. Autumn Foliage Private-Car Restriction (マイカー規制)

During peak "Carpet of the Gods" autumn foliage season (typically late September through mid-October), private cars are restricted from driving all the way up to Iwakagamidaira during daytime hours to prevent severe mountain road gridlock:

• Drivers park at the designated temporary lot (such as Ikoinomura Kurikoma Parking Lot [いこいの村栗駒跡地駐車場]) and board a paid shuttle bus to Iwakagamidaira, Paying an environmental cooperation contribution (環境保護協力金).
• Exact dates, operating hours, and shuttle fees change each year—always check the latest notice on Kurihara City Official Website — Mt. Kurikoma Autumn Foliage Traffic Regulation and Visit Kurihara News before visiting in autumn.

3. Winter Road Closures & Volcanic Trail Restrictions

• Winter Road Closures: Prefectural roads leading to Iwakagamidaira and across Mt. Kurikoma (including Miyagi Prefectural Route 42 and National Route 398 / Kurikoma Road) close for winter snow from late November through late April / May. Check current road opening dates on Miyagi Prefecture Winter Road Closures (宮城県冬季通行規制) and Iwate Prefecture Road Information (岩手県道路情報提供サービス).
• Volcanic Gas Restrictions: Although Mt. Kurikoma is currently at Volcanic Alert Level 1 (Normal), localized high-concentration volcanic gas zones keep the Kagamiishi / Yuhama Course (カガミ石・湯浜コース) between Mt. Tsurugi (剣岳) and Showako (昭和湖) closed to entry. Check Miyagi Prefecture Tourism — Mt. Kurikoma Trail Status before planning routes outside the Iwakagamidaira and Sukawa corridors.
