Japan has also been considering lifting the ban on sports betting for several years, with the aim of relieving the sports industry, which has fallen into a slump due to the coronavirus, and securing financial resources. The Ministry of Economy, Trade and Industry and private companies are already preparing to create a framework for sports betting. In December 2020, the toto law will be revised, and from 2022, the basketball B league will be added to the toto lottery. In the future, other sports may be added to toto's target, and the day may come when the ban on sports betting will be lifted.
