Akimoto isn't wasting any money at all. He is getting paid for official usage of his current idol concept, the 48 groups. For there to be a foreign 48 group in the first place, it has to be accepted by AKS etc., and its standards must adhere to Akimoto's concept and philosophy. The only thing he may be wasting, is time and energy, as he will necessarily have to be involved somehow, and I honestly don't care at all about any of the foreign 48 groups, and think he should instead be spending time and energy on the Japanese 48 groups, and here there's just too much to mention. So yeah, he makes money on this.
