It is an another world hidden in the nature of a grand garden. There are "Kurogane suigen source" and "Baba suigen source" in the garden and they make streams and a marsh. There are many freshwater crabs and fireflies in the streams and the only mizubasho or Japanese skunk cabbages in Kyushu are in the marsh. There is also an ume or plum garden.
