„To allow more time for students to repeat lessons, conduct observations and experiments and write reports, Japan’s 2008 curriculum reform increased both content related to knowledge and skills and instruction time. The 2017 reform, to be implemented in elementary schools starting in 2020, will further expand the curriculum to cover content related to foreign languages and computer programming and will further increase instruction time.“
