Trip Report: Kijima Kogen Amusement Park in Beppu, Kyushu
I had to wait a while for the bus to take me back down the mountain and back to Beppu. I timed lunch properly and got to the bus stop a few minutes before it was due, but due to massive amounts of traffic caused by Golden Week tourists (mostly going into the park) I sat in the cold for 30 minutes. I should note the bus only runs about once an hour, so check the schedule!
As I mentioned earlier, Kijima Kogen is located in the hills of Beppu, and is easily reached by bus from Beppu Station. Ask at the tourist information desk in the station for which bus to take and a schedule with return times. The park has a limited English website here. Admission right now is 1500 yen, with per-ride charges of up to 1000 yen (for Jupiter) - a free pass with admission is 3800 yen, and is your best bet if you're planning on riding all the coasters. The park also has a hotel and golf course!
