Kuju Highland — Kyushu's finest starry grassland at the foot of the Kuju Mountains

Overview

Kuju Highland is a highland area at about 800m elevation sprawling across the southern foot of the Kuju Mountain range in Taketa City, Oita Prefecture. Protected as part of Aso-Kuju National Park, this vast grassland is loved by astronomy enthusiasts as one of Kyushu's most beautiful stargazing destinations.

Observation environment

Kuju Highland sits in central Kyushu near the Kuju Mountains, positioned well away from major cities like Oita and Kumamoto, ensuring minimal artificial light interference.

The vast grassland at about 800m elevation offers unobstructed horizons, with over 180-degree panoramas extending from the southern sky. At Bortle Scale Class 2 darkness, the Milky Way appears powerfully. The sight of the Milky Way rising against the Kuju Mountains' silhouette is spectacular—a signature scene of Kyushu's stargazing heritage.

Recommended observation points

Several viewing parking areas line Kuju Highland's main road, each offering different sky directions. Kuju Highland Overlook particularly opens to the south, ideal for summer Milky Way photography.

Staying at Kuju Highland Cottage allows you to enjoy the starry sky from the grounds with minimal artificial light, even featuring a rotenburo (outdoor bath) overlooking stars.

Access

About 50-60 minutes by car from Kuju IC on the Oita Expressway. From the Kumamoto area, access via Aso is also possible.

Stargazing tips

Grassland radiation cooling is strong; on clear nights, temperatures drop rapidly. Even summer evenings fall below 15°C, so bring a light fleece or windbreaker. Pastureland fences and private property require respect—don't trespass.
