I did a little statistical research on players who have come over from the Nippon League and how they did in Major League Baseball compared to their stats back in Japan. I took 5 players, Ichiro, Hideki Matsui, Kaz Matsui, So Taguchi, and Tadahito Iguchi. I placed the most weight on Ichiro and Hideki matsui because of sample sizes and their success.

I studied 5 categories BA, HR, SLG, OBP, and K's. I based them on 550 AB's. I won't go into too much detail about the exact calculations, but be sure that I considered sample sizes, prime ages (approx 28-32 yrs old), present success over past success, etc.

What I came up with is this:
BA - 92.4%
SLG - 80.1%
HR - 50.2%
OBP - 82.9%
K - 95.0%

for example, a player will hit 50.2% of his Japan HR total per 550 AB's in MLB. Both Ichiro and H. Matsui have hit 43-44% HR's, but the totals by Iguchi (59%) and S. Taguchi (113%) bumped my estimate to 50.2%. By this HR example, I hope you can get an idea on how I got the other statistical converstions

Now, I know this isn't an exact science and a lot of it is subjective. But the best way to convert the statistics/ratings is to base it off of past events and the best way to do such is by looking at how these players did. I also understand that if any Nippon Lg player were to make the jump, their statistics would not convert exactly like this, but I would bet it would be somewhat similar with a large enough sample size.

What I would like to do is make a Nippon League roster set that can be exported/imported into any Universe so that OOTP'ers can have that added realism of having the second largest Pro Baseball League in their Universe
