January 16, 2024 Results of FY2022 Rate Survey on Broadband Infrastructure Development

The Ministry of Internal Affairs and Communications (MIC) conducts a rate survey on broadband infrastructure development every year to further spread and develop information and communications infrastructure in the future.
Recently, MIC compiled the survey results of the development rate of optical fibers at each household (per municipality) at the end of fiscal 2022, and MIC has decided to open the results to the public.

1. Rate survey on broadband infrastructure development

MIC surveyed telecommunications carriers providing broadband services to general subscribers with their equipment, as well as telecommunications carriers borrowing facilities provided by local governments under IRU contracts to provide services in their broadband service areas. The Ministry of Internal Affairs and Communications (MIC) obtained the results from the estimated number of target households in the area divided by the total number of households (rounding down to the second decimal place) based on information from the telecommunications carriers and the Basic Resident Register of each area.
Note: MIC’s estimation was based on certain assumptions from information from telecommunications carriers, and it should be kept in mind that errors may be included.
Furthermore, the actual provision status may vary depending on the geographical conditions of each provision area and the facility condition of each building.
