The top comment in the third link points out that Microsoft Japan later walked back the productivity claim: In the announcement dated October 31, one of the listed "improvements" from the 2019 Summer Work-Life Choice Challenge was an increase of 39.9% in labor productivity (sales revenue per employee) in August 2019 compared to August 2018, with a graph below.

To avoid misunderstanding, we have removed that claim from the above summary of the direct effects of the challenge.
