In May 2026, three major Japanese food manufacturers (matcha and wagashi brands) simultaneously launched limited edition packaging products featuring Japanese old coin designs. A series of canned matcha, yokan, and senbei products inspired by Edo-period Ichibu-gin, Kanei Tsuho, and Meiji gold coins launched exclusively at department stores and online, recording over double normal first-week sales. The commercial use of cultural heritage motifs is drawing attention for its effect on expanding awareness of the old coin market.
