Entertainment giant Sony is the latest company to jump onto a bandwagon of Japanese businesses seeking to tap blockchain technology, a trend that poses challenges for the nation’s government.

Sony last month officially unveiled a digital ledger, Soneium, anticipating that developers will use it to create applications to enhance the firm’s offerings. Precisely how is a work in progress, but the broad idea is that intersecting Soneium with gaming, music and movies could yield opportunities.

Other Japanese firms exploring various blockchain-related initiatives include the likes of Nippon Telegraph & Telephone, Toyota and Mitsubishi UFJ Financial Group. The latter, Japan’s biggest bank, is looking into issuing stablecoins, a type of digital token meant to hold a constant value.
