Kijima Kogen Park sits on a breezy highland plateau above Beppu, an amusement park with mountain air, views toward the Kuju ranges and a ride lineup headlined by Jupiter, the first wooden roller coaster ever built in Japan. For families working hot spring country into their Kyushu route, it adds a day of screams to all that steam.
Jupiter remains the reason enthusiasts make the trip, a classic timber coaster whose rattle and roar no steel track reproduces. Around it run a solid supporting cast: family coasters, a big wheel with volcanic views, water rides for summer and a generous kids zone, so the park works for mixed age groups rather than thrill seekers alone. Queues are short by big city standards on all but peak holiday dates.
The park lies on the scenic Yamanami road between Beppu and Yufuin, which makes it easy to fold into an onsen itinerary; an adrenaline morning followed by an afternoon soak is a very good day. The highland location runs cooler than the coastal cities, pleasant in summer and genuinely cold in winter, so dress accordingly.
Buses from Beppu Station toward Yufuin and the highland serve the Kijima Kogen Park stop in around 30 to 40 minutes. Beppu connects to Hakata in Fukuoka by the Sonic limited express in about two hours. Drivers take the exit near the Beppu interchange on the Oita Expressway.
Is Jupiter rough? It is a wooden coaster, so expect honest shake; that is the charm.
Is the park open year round? It operates through the seasons with some weather closures, so check the calendar for your date.
