Spending on Foreign Players
Let’s take a look at how actively teams are spending on foreign players. Each NPB team is allowed to only have four foreign players on its 25-man roster, but there is no organizational limit on foreign players. Many teams choose to hold more, and allow them to compete for a roster spots. As you can see in the rankings, many teams are unable to maxmimize the foreign player slots on their 25-man roster.
Out of 39 foreign players on NPB 25-man rosters, 13 have previous experience in Japan with a different team. In-season additions like Jose Ortiz for the Softbank Hawks and Scott McClain by the Hiroshima Toyo Carp are two recent examples of this,  showing how teams are more likely to take a risk on a player that knows Japanese baseball rather than looking for new talent overseas.
