Japanese honeybee hive, Nihonmitsubachi, Japanese honeybee, stacked hive, 3 tiers. We use naturally dried cedar wood. As a countermeasure against the recent heat, the bottom board can be replaced with two types: the standard type and a 6mm mesh wire net. You can easily inspect the inside with a smartphone, mirror, etc., by removing the bottom board. The upper part is made of plywood with slits to accommodate wax moth, Varroa mites, and a winter feeding box. Four metal rods are included as a measure to prevent the honeycomb from falling. Instructions for use are included in the letter containing the bee-attracting know-how. Although we strive for high precision in manufacturing, there may be slight dimensional errors due to handwork and warping of the wood. Thank you for your understanding.
