Chino-ike is one of the most colorful of the Jigoku, or "Hells," in the Beppu thermal area of Tsurumi volcano on the Japanese island of Kyushu. Steam rises above the iron-stained, vermillion hot-spring pool. Other pools in the Beppu area are milky, light blue, greenish blue, or indigo blue.

Mudpots are a common feature of the Beppu thermal area on the flanks of Tsurumi volcano on the island of Kyushu. Beppu is one of Japan's most noted thermal areas, containing hot spring pools of varying water color, hot beach sands, and many hot spring resorts.

Steam clouds almost obscure the famous hot-spring city of Beppu, along the east flank of Tsurumi volcano. The colorful hot-spring pools and mudpots of Beppu, located along the shores of the scenic Inland Sea, form one of Japan's most noted thermal areas. The Tsurumi complex consists of two large domes, Tsurumi and Yufu, and three smaller domes on the north flank of Tsurumi. The largest dome, Yufu-dake rises to the west. A single eruption, from Tsurumi in 867 CE, is known in historical time.

Yufudake, the westernmost of the two large lava dome complexes of Tsurumi volcano, rises to the NE of the city of Yufu in northern Kyushu. Three smaller lava domes are located on the N flank of the eastern dome. A historical eruption occurred in 867 CE.
