The Yamanami Highway (やまなみハイウェイ) is one of Japan’s most breathtaking scenic routes, stretching for about 60 kilometers (37 miles) through the heart of Kyushu, connecting Yufuin in Oita Prefecture with Aso in Kumamoto Prefecture.
Despite its name, it’s not a “highway” in the sense of a toll expressway — it’s a two-lane mountain road, perfect for a leisurely drive surrounded by the natural beauty of Japan’s countryside.
A Journey Through Japan’s Most Beautiful Countryside
The Yamanami Highway winds through the Aso-Kuju National Park, offering panoramic views of vast grasslands, volcanic peaks, and seasonal landscapes that change dramatically throughout the year.
-
Spring: Cherry blossoms and fresh greenery brighten the valleys.
-
Summer: Lush meadows and blue skies create postcard-perfect views.
-
Autumn: The rolling hills burst into brilliant shades of red and gold.
-
Winter: Frosty mornings and snow-capped peaks create a quiet, otherworldly beauty.
No matter the season, the route offers ever-changing scenery that makes it one of Japan’s top road trip destinations.
Highlights Along the Route
Here are some of the most popular stops along the Yamanami Highway — perfect for a self-drive adventure or a guided tour:
1. Yufuin Onsen (由布院温泉)
Start your journey from Yufuin, one of Japan’s most charming hot spring towns. Stroll through the Yunotsubo Kaido, enjoy local sweets, and take in the majestic view of Mt. Yufu towering in the distance.
2. Mt. Yufu (由布岳)
Nicknamed the “Bungo Fuji” for its elegant conical shape, Mt. Yufu offers hiking trails for all levels. The 1,583-meter peak rewards climbers with sweeping views of both Oita and Kumamoto.
3. Kuju Plateau (久住高原)
The Kuju Mountains are a paradise for hikers and photographers. Visit the Kuju Flower Park, where over 5 million flowers bloom from spring to autumn — including tulips, lavender, and cosmos.

Spanning 390 meters across a deep valley, this is Japan’s highest pedestrian suspension bridge. The views of waterfalls and the surrounding mountains are simply breathtaking.

The road continues into the Aso region, home to one of the world’s largest volcanic calderas. You can visit Mount Aso, still active, and see smoking volcanic vents up close at the Nakadake Crater (check current access conditions before visiting).

Just off the Yamanami Highway lies Kurokawa Onsen, a secluded hot spring village famous for its wooden ryokan inns, riverside baths, and traditional atmosphere. It’s a perfect place to stay overnight and soak in natural hot springs surrounded by forest.
