The db does include most of the Japanese players who had careers of 15 or more years.

You will also noticed that a few Japanese pitchers have very good ML careers as starters due to their very good ratings in not allowing HR's. I assummed this was because Japanese players in general hit fewer HR's than players in the states. So I normalized for that and found out that it actually turned out that a few of the Japanese pitchers were just really, really good at not allowing HR's and that in many cases this was their main skill. Most Japanese pitchers allowed a "normal" amount of HR's once the leagues were normalized to each other but a few were just light-years ahead of their brethren. Since in some cases this was that players main skill and since in reading quite a few books on the Japanese Leagues I noticed that these players worked on that skill constantly and developed specific pitches to produce that skill I left them with that skill in the db. I think they really might have been that good if given the chance in the major leagues just like many of the negro players might have been. No one will ever know for sure.

If you wish to remove Japanese players simply delete all records in the Master.csv with Japan in the college field. Negro leaguers have Negro in that field.
