Trifa, which has established itself as the No. 1 in the overseas eSIM business, is entering a next phase that goes beyond the bounds of being just a startup, challenging itself with huge ambitions. One goal is to become a service used worldwide. Another is to transcend the eSIM product framework and become a comprehensive travel infrastructure. Yet another is to become a key player in a new era where Japan once again demonstrates its presence in the world. The ambitions are grand, trust the instincts, the strategy is intricate, and the actions are down-to-earth. I look forward to meeting future companions who will walk together with us.
