Investment is a real success story in both directions. Both Canada and Japan are extremely active in each other's market, and there are household names in terms of the major Japanese companies that are operating in Canada already: Honda, Toyota, Bridgestone, Canon, Fujitsu, and on and on. They're also increasingly active in the energy sector.
We both have advanced, predictable, stable legal systems, so the incremental benefit of having access to international arbitration between Japan and Canada may not be as great as it would be with a different partner, but the greater security that you have through a rules-based framework will provide an additional level of stability and security for investors seeking to go into those markets.
