It takes longer than usual to boil water in an iron kettle.

A large iron kettle is useful because it can boil a lot of hot water at once.

It is also recommended when using it on a stove or in a brazier.

The longer you put it on the fire, the more the iron kettle will melt out and the more mellow it will be.

​ Designed by modern master craftsman Katsuhisa Sato, you can use it as if it were lifted up for its size.
