A list of the most active GitHub users

Most active GitHub users in Japan

This is a list of most active GitHub users in Japan over the past year. Other countries/regions can be found here. This list was generated at 2025-12-15 15:07:12 +0000 and machine-readable JSON is available for:

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)

This list contains all contributions for each user (public & private). There are 128307 total users in the region and you need at least 211 followers to be on this list.

Badges are also available, which you can include on your profile pages. Simply include the following markdown for users: 

[![committers.top badge](https://user-badge.committers.top/japan_private/USERNAME.svg)](https://user-badge.committers.top/japan_private/USERNAME)
For organizations, you need to use a slightly different markup: 
[![committers.top badge](https://org-badge.committers.top/japan_private/ORGNAME.svg)](https://org-badge.committers.top/japan_private/ORGNAME)
In case you aren't currently ranked on this page, you'll simply receive an "unranked" badge.
