Sparkling stoneware amid the fields of Tokachi that I encountered when I was a child
This used to be a land where Japanese people lived very prosperous lives. There is nature, such as the Higashi-Taisetsu Mountains and lakes, that is unique to this place as well as an expansive plain.
I became interested in Tokachi stone when I was a child. Obsidian has been treated as a treasure since ancient times as a material for making stoneware (arrowheads). In the fields of Ashoro, the town I grew up in, numerous arrowheads could be found. They appeared to be glowing in the fields, and were very beautiful. The arrowheads I found were my treasures. Since we used to use horses to till the fields, we could pick up arrowheads. We no longer hear stories like this anymore.
When I was a child, I closely observed an arrowhead I had picked up, wondering how it had been created. Since that time, I have been very interested in obsidian. Immediately after I landed a job, I happened to find this (holding the arrowhead he created in his hand) at an archaeological museum in Tokyo, a city to which I was not yet accustomed. The article visitors would first notice when entering the museum was the garrowheadh from Hokkaido. I still vividly remember my amazement at that time.



The pleasure of unraveling an ancient mystery
@I then began researching about how the arrowhead was created. I read literature and challenged myself in my research. I gradually came to learn more about obsidian and techniques used for making arrowheads. After cutting out obsidian in the form of plates, you need deer antlers.
You then carefully carve the stone. It is common knowledge that traces of finely made carvings remain as many faces on arrowheads (pointing at the arrowhead). What tool was used to form this arrowhead? It was a deer antler. People used deer antlers to carve obsidian. Although soft piths are found on the antler, their surroundings are very hard. Soft piths get caught on the stone. The combination of these two things makes it possible to carve the stone. I am certain that this is how arrowheads were created.
