Development of the 1966 Red- Large Size Red Public Telephone Set
| As direct intercity dialing spread across Japan during the 1960s, demand grew for a new public telephone capable of handling nationwide direct-dial calls. In 1965, a prototype large-sized red public telephone was installed at Tokyo Station to test this emerging technology. Fully introduced in June 1966, the new model allowed callers to dial distant regions directly using area codes beginning with “0,” eliminating the need for operator assistance. The telephone featured a lower, more streamlined profile than earlier red phones and was distinguished by a gold band marked “For Direct Long-Distance Calls.” It symbolised Japan’s rapidly modernising telecommunications network.
