Most active GitHub users in Japan

This is a list of most active GitHub users in Japan over the past year. Other countries/cities can be found here. This list was generated at 2019-04-22 00:04:14.324383837 +0000 UTC.

This list is generated with this piece of code. The logic is as follows (in pseudocode):

githubUsers.sort(_.followers)
           .filter(_.location == 'Japan') 
           .take(1000)
           .sort(_.contributions)
           .take(256)

Private contributions are included if the user has selected that option in their profile settings.
