Two decades after Japan rolled out an ambitious plan to go digital, the COVID-19 crisis has exposed the government's deeply rooted technological shortcomings as ministries remain stuck in a paper-driven culture that experts say is hurting productivity.

While Tokyo has made "digital transformation" its main policy plank this year, the switch may not prove so easy as bureaucrats from different ministries still aren't able to hold teleconferences together and little of their administrative work can be done online.

Analysts say the lack of government digitalization could reduce the incentive for the private sector to go digital in a blow to the country's efforts to boost productivity.
