Class groups are based on Japanese academic year

Shibuya International Rugby Club classes are based on Japanese academic year, so we are able to play games with local Japanese teams. 

Japanese academic year starts in April and ends in March of the following year. 

To be precise, children who were born between 2nd April and 1st April of the following year are placed in the same grade. This is also in accordance with guidelines set by the Japan Rugby Football Union.

Therefore, some continuing members will move up the class age group from April. Applicable members will be notified in March.
