Master: Yashiro Tetsuen (八代鉄園 / 八城鉄園), Heisaburo Hamatsu (浜津平三郎)

AKA Nidaime Tetsuen (二代目鉄園). Born on 17 October 1932 in Tochigi Prefecture, Chiyoko Hamatsu married kokeshi craftsman Heisaburo Hamatsu in 1956 and began painting dolls turned by her husband. In 1970, she adopted the artist name Nidaime Tetsuen (Second Generation Tetsuen) to preserve the distinctive style of her brother-in-law, Yashiro Tetsuen (1904–1960). Her works combined traditional Yajiro influences with the decorative designs of the Tetsuen style, continuing an important artistic legacy until her death on 16 October 2007.
