Sometimes I think it would be a good idea for you to learn Japanese. Then you could understand what the Japanese coaches, especially Shinji, are saying and writing.
I gather that spoken Japanese is quite feasible but written Japanese more of a challenge. Still, since you already have a fair grasp of more than one European language, you have a head start.
Of course once you have a basic knowledge of the language you need to get a command of the swimming terminology and specifically the TI terminology, which is a language in itself. ;-)
