The Contract Agreement system is a system for the transfer of baseball players between the Japanese Professional Baseball (NPB) and the American Professional Baseball (MLB).

Manuscripts of a system of contract agreements between the US and Japan launched in 1967 to control NPB players to the MLB, but problems began to arise in the late 1990s. One problem was one. The number of teams in the NPB that lost their non-compensated stars was of interest after two of the tournaments stars. Hideo Nomo and Alfonso Soriano, came to MLB after using a hole to circumvent contract compensation. In addition the players have little bargaining power if the team decides to sell them to MLB. In the case of Hideki Irabu came to an MLB team when he didn’t want to. In 1998, they rewritten the system to address these two problems. As a result, the system became a “notification system”.

When an the NPB decide to post a player, his team will notify the MLB commissioner and offer a sale of no more than $ 20 million. The player then has 30 days time to negotiate with whichever MLB team is willing to pay the club price. If a player agrees to a team agreement 30 days in advance, they will receive the announced fee as a transfer fee . And the player will entitled to play in the MLB tournament. If no MLB team has agreed with a player, the player will return to his or her team. This transfer method replaces the old way in which the MLB tournament held an auction. Many teams would register. They offer an unlimited price to win the right to deal with the player posted for a 30-time period. The player only negotiate with that team when they decide the highest price.

They posted 20 players on this system. Among them, 11 were signed for the pro, 3 were for an amateur, 4 failed to attract teams, and 2 were unable to reach a contract within 30 days. The four stars transferred through this system in MLB are Ichiro Suzuki, Daisuke Matsuzaka, Yu Darvish, and Masahiro Tanaka. The first three contracts priced at $ 13,125 million, 51.1 million and $ 51.7 million, respectively. Tanaka is the first player to adopt this system according to the current procedure. He posted for the highest price under the new law. However, since its implementation, they have criticized in the media and in internal baseball populations from both countries.
