yamamaru  ヤママル窯

YAMA-MARU Kiln locates deep in the mountain of Koishiwara Sarayama. Master ceramist Jiro Kajiwara (13th generation) and eldest son Hizuru Kajiwara (14th generation) work relentlessly to carry-on the 350-year-old tradition of Koishiwara pottery. 

Their kiln symbol (the reverse "V", and the "circle")  represents their kiln location, an old way to communicate an address.  It was said because their kiln locates on the top end of the village lane, they became known as YAMA (mountain) MARU (zero). The next kiln was named YAMA (mountain) ICHI (one), so on and so forth.
