“At Umi Jigoku’s spacious garden, you may find the beautiful “Sea Hell” that features a blue pond of boiling water. There are also secondary orange colored hells, as well as a large, clear water pond with lotus flower. The leaves are said to be strong enough to carry small children.
Rather than it be used for bathing, the “Hells” are hot springs made for viewing. Six of the 8 hells are in the Kannawa district (Oniishibozu Jigoku, Shiraike Jigoku, Kamado Jigoku, Oniyama Jigoku, Yama Jigoku) and another two in the remote Shibaseki district (Chinoike Jigoku, Tatsumaki Jigoku)”
