The bow and arrow were hunting tools invented during the Jomon period. Obsidian was a popular material for making arrowheads due to its sharp edges when fractured.
The Jomon people crafted arrowheads by pressing the tip of a deer antler against the edge of a thin obsidian shard, carefully chipping away small pieces to shape it into a clean, triangular arrowhead.
At the museum, even first-time visitors can try their hand at stone tool making. Instead of deer antlers, participants use a ‘pencil’ tool with a copper wire tip to craft arrowheads just like the Jomon people did. Once completed, the arrowhead is attached to a decorative display card featuring a bow and arrow to finish the project.
(Please note that the bow and arrow on the display card cannot be used to shoot arrows.)

Following the same process as arrowhead-making, visitors can create their own unique keychains by shaping obsidian into their desired design. The edges are then smoothed to make the pieces safe for daily use.

Bone tools, known as kokkaku-ki, were made from animal bones and antlers. Because organic materials decompose over time when buried in the ground, fewer examples have been found from older periods. However, it is believed that such tools were in use as far back as the Paleolithic era.

At Jomon period archaeological sites, including cave dwellings and shell mounds, various bone and antler tools have been discovered. These include fishing hooks and harpoons for catching fish, needles for sewing leather, and even hairpins and other accessories.
At the museum, visitors can try their hand at making a bone pendant. The process involves shaping a hard cow thigh bone by wetting it with water while carefully grinding it with a whetstone, then polishing it to a smooth finish with sandpaper.
