The actual year is unreadable. The era "Bunsei" is legible.
There's another clue next to "Bunsei" on the left. It's the kanji for "snake" as in T. It's a 12 year cycle so this would be 1821, The 4th year of Bunsei. A natural wood hibachi like this had to be found as a stump in the forest. When a tree was cut down just the stump was left behind.
Sometimes the stump started growing again around its outside edges. The interior of the stump being dead would rot away. For someone to make a hibachi like this, they had to wander the forest, find a stump that had grown around its edges, (where it had been cut down), then the finder would dig around the base.Cut away the bottom of the stump and bring it home. From there they would make a wood base and line the interior with metal, usually copper. To use it they would take ashes from another hibachi fill this hibachi with them and burn a handful of charcoal to generate heat during Japan's winters. These are usually used as decorative flower arrangements.
