The item shown in the image is an authentic Showa-era retro enamel sign for the “Noritsu-go” bicycle, which was once manufactured and sold by Okamoto Bicycle Co., Ltd. Brand/Product: This is an advertising sign for the “Noritsu-go,” a utility bicycle that was popular from the pre-war period through the mid-Showa era. Design: The red triangular mark in the center bears the kanji “能率” (Nōritsu), with the English spelling “NORITSU” inscribed below it. The section resembling a blue ribbon features the text “Noritsu-go” in white lettering; this is an extremely rare, irregularly shaped, double-sided sign. Historical Background: “Noritsu Co., Ltd.,” a major home appliance manufacturer now famous for water heaters and other products, was originally established in 1951 as “Nōritsu Bath Industries Co., Ltd.” The name “Noryoku” and the triangular logo have a deep connection to this iconic “Noritsu-go” bicycle: the founder named the company with the aim of creating the “Noryoku of Bathing,” drawing inspiration from this legendary bicycle. Enamel signs from that era are highly sought after among collectors, and this piece possesses the unique charm of a vintage item—including its rust and signs of aging.
