Sado is an island northwest of Niigata. Gold was mined in the mountains on the island from the Edo period until 1989. 佐渡島は新潟の北西にある島です。島の山では江戸時代から1989年まで金が採掘されていました。
Wood ashes of sufficient quantity and quality to fill a naga hibachi are hard to find in the states. Diatomaceous earth is too light. I did find that ground pumice works well though.
Pumice stone under the ashes works very well. Ashes should be made from burned grass or wood, but they are hard to find. Ceramic ashes are easy to get, but sorry, I have never used them and don't know how to use them.
