With the likes of South Africa and Scotland based in Wrexham, New Zealand, Ireland and Argentina battling it out in Cardiff, Australia, England and Fiji entertaining crowds in Newport and Wales hosting France and Italy in Swansea, there is something for everyone.
IRB Tournaments Manager Philippe Bourdarias said: "A significant level of excitement and interest has already been generated throughout Wales ahead of the championship, thanks to the superb work of the Welsh Rugby Union.
"Today's announcement of a competitively priced ticketing structure underlines the WRU's commitment to making the championship available to all across all four regions and will serve to further heighten expectation and excitement.
"With double header matches played across all four venues on each match day, the IRB Junior World Championship offers an excellent opportunity for the rugby Community within Wales to see the next generation of Rugby World Cup stars in action as they follow in the footsteps of Ryan Jones, Dan Carter and Mathew Tait."
WRU Group Chief Executive Roger Lewis said: "The future stars of the world game will be literally on the doorstep of the majority of Welsh people. Whether you live close to Cardiff, Newport, Swansea or Wrexham, there will be a real feast of international rugby for all to enjoy and savour.
"We were determined for this tournament to be accessible to all and coupled with the top teams playing in all four corners of the principality, this ticketing strategy allows us to make that happen.
"Individuals and families that may not ordinarily be regular rugby watchers can take the opportunity to come along and enjoy an entertaining evening out for all the family.
"In addition to the tickets on sale, hundreds of school children across Wales will have the chance to watch the matches as part of a tournament legacy programme funded by the Welsh Assembly Government."
