Tanimura Tango’s family have been hand crafting chasen for 20 generations, or for about 500 years. The family settled in the hills of Takayama in Nara Prefecture around the year 1500. It was also around this time that bamboo chasen, the kind still used today, were originally created. Today, Yamato Takayama produces around ninety percent of the chasen made in Japan.
