This is a site about Pro Yakyu (Japanese Baseball), not about who the next player to go over to MLB is. It's a community of Pro Yakyu fans who have come together to share their knowledge and opinions with the world. It's a place to follow teams and individuals playing baseball in Japan (and Asia), and to learn about Japanese (and Asian) culture through baseball.
It is my sincere hope that once you learn a bit about what we're about here that you will join the community of contributors.

To sum up, it basically says that major league baseball in Japan is almost at the same level as in the US/NA. Previous comparisons had been comparing it to AAA in the US/NA, but that had been unfair. It's much closer to MLB than AAA
