One of those titles would be a Japanese Youth Title, which would be there for fighters 24 years old or younger. The idea of the title would be for the youngsters to get title experience whilst still prospects and being able to get competitive bouts that mean something for both men involved. The title would likely be avoided by many of the top prospects, such as fighters who have come from long amateur backgrounds, but could be a good stepping stone between Rookie of the Year and the regular domestic title, which many Rookies are unready for until a year or two after they have competed in a Rookie tournament.
The other title was a Japanese female title, which is being looked at as a way to keep female boxers in the sport and to give them a stepping stone to OPBF and world titles. At the moment the JBC only recognises OPBF female and female world titles but a domestic title would, they think, keep fighters in the sport and give them a chance to fully prepare for the best in Asia, if not the world.
Although neither title has been officially announced it does look like both titles will be introduced in the near future. It could cause problems down the line, but it could also help the Japanese scene with fighters having another clear steppign stone en route to bigger and better things.
