JETRO Invest Japan Report 2022
Chapter3. Recent Government Policies Section4. Review/Extension of 5G Introduction Promotion Tax

5G, the next-generation network standard of which service is now available in Japan, is attracting attention as an ICT infrastructure to contribute to solving local social issues in regions, such as automated delivery and smarter factories. The 5G Introduction Promotion Tax was introduced with the passage of a bill to partially revise the Income Tax Law and other laws in the Ordinary Diet Session in 2020. The 5G Introduction Promotion Tax aims to propel the expansion of 5G networks by providing tax incentives, such as tax credits or special depreciation on the amount of the investment, for specific national and local 5G capital investments made per approved deployment plans.

In the tax reform for FY2022, the system was revised to accelerate the development of base stations, especially in rural areas, toward the realization of the "Vision for a Digital Garden City Nation." Its application period has been extended by three years with the introduction of descending tax credit rates to promote intensive development over the next three years. Chart 3-4 shows eligible businesses, tax credit rates, etc.
