Oita Bungoono Outing Information
❚ Inazumi Underwater Cave Sightseeing Boat
At the Inazumi Underwater Cave in Mie Town, Bungoono City, Oita Prefecture, you can enjoy an experience of an underwater cave and firefly river sightseeing boat.
The cave maintains a temperature of about 16°C throughout the year. A serene atmosphere allows you to leave the summer heat behind and feel the charm of the cave submerged in water. The Inazumi Underwater Cave is said to have formed over approximately 200 million years and was submerged during the great eruption of Mt. Aso around 85,000 years ago. You can slowly enjoy the depth that cannot be touched just by walking around, from the comfort of the boat. The sightseeing boat moves under the guidance of staff, taking about 10 minutes. While listening to the formation and highlights of the cave, you will explore the interior from the water's surface perspective. Why not try experiencing the quiet time spread across the bottom of the cave?

It is organized by local residents to promote regional revitalization and raise awareness of the Sugao rock-carved Buddha. The "Rooster Imitation Contest" is based on local legends. According to the legend, an oni (demon) that had settled in the area demanded, "Give me a village girl as a bride!" The troubled village chief consulted a monk, who told the oni, "If you carve five stone Buddhas into the cliff in one night, I will give you a daughter as a bride; if not, you must leave the village." Concerned villagers went to check at night and found the oni carving the fifth statue. They had the village's rooster imitation master imitate a rooster's crow, tricking the oni into thinking it was morning, causing it to flee. ■■ Access from Fukuoka Prefecture and Kumamoto Prefecture to the center of Bungoono City ■■■ About 3 hours by car from JR Hakata Station in Fukuoka Prefecture About 2 hours by car from JR Kumamoto Station in Kumamoto Prefecture About 1 hour and 20 minutes by car from JR Beppu Station in Oita Prefecture About 1 hour and 20 minutes by car from JR Yufuin Station in Oita Prefecture ■■■■■■■■■■■■ Introducing tourist attractions and recommended spots in Bungoono City, Oita Prefecture ■■■■■■■■■■■■
