Projected Boost in Japanese Exports

In a recent article in The Japan Times, Japan is expected to see a 23% boost in exports. Most of this increase will come in the form of electronics. This a result of the TPP cutting 87% of tariffs on industrial products. Japan will also see a boost in agricultural exports specifically beef. How will this boost affect the importation of these products into Japan? How will this affect other countries domestic products? Where might Japan see a decrease in exports?
