Development of the 1972 PINK DOMESTIC
| This is an early version of the Japanese “Pink Telephone” (ピンク電話), officially known as a Tokushu Kan’i Kōshū Denwa — a “Special Simplified Public Telephone.” These telephones became one of the most distinctive features of everyday Japanese streetscape and shop culture during the late Shōwa era. The sign beneath the phone explains that the system was formalised in December 1959 (Shōwa 34) to help compensate for shortages of ordinary public telephones and to reduce illegal use of subscriber telephones. Unlike fully public street payphones operated directly by NTT, pink phones were privately installed in businesses such as cafés, tobacconists, restaurants, hotels, barber shops and small stores. Shop owners entered into agreements with the telephone company allowing customers to make calls using the business’s subscriber line in exchange for coin payments. Interestingly, this shape did not appear to be very popular in Japan, but was widely copied elsewhere. A red version was widely used in Australia. This example is especially interesting because it has a transparent demonstration casing, revealing the internal mechanisms normally hidden inside the moulded shell. The visible rotary dial assembly, coin pathways, internal cash box and electromechanical components illustrate the rugged engineering that allowed these phones to survive constant daily public use. Most pink phones were designed primarily for local calls and usually accepted 10-yen coins. Earlier versions used heavy metal housings, while later models adopted smoother moulded plastic forms such as this one. By the 1970s and 1980s they became ubiquitous throughout Japan, functioning as a semi-public communication network embedded inside ordinary businesses rather than in street booths alone. |
