The KIDL was established to support grass-roots rugby development around Tokyo, by providing an entry level competition.​

The focus is on teams and clubs which, for a variety of reasons, are not ideally served by the current structures. Supporting their development at a rate which suits them.


The JRFU does an outstanding job of providing a strong competition framework for high schools across the country. The system produces some extremely good players, has a long history and to many of those who play in it, it represents the ‘peak’ of their rugby career. We are very respectful of the existing competition framework. However, such strong and demanding competitions can act as a barrier for some teams.


Teams enter such competitions before they are ready because there is no viable alternative and have difficulty.


International school teams, regular Japanese school teams and also youth 'club teams' are all offered an alternative by the KIDL. 


Currently the league is competed by 5 TEAMS.


The aim will be for the league to build as more teams wish to join.


New and developmental sides will have the opportunity to grow while enjoying competition. The emphasis will be on getting games played (i.e. through matching numbers, loaning players etc, with the results secondary).


Should we build sufficiently we will look to put in place a more competition focused structure if that is required.


Potentially school teams participating in other competitions could also benefit from playing fixtures with KIDL teams.


An additional goal is to add open access development activities led by invited guest coaches to the league schedule.


Most of the fixtures are played between September and March, although fixtures may fall outside of this period should teams need them to do so.
