Trifa, the Tokyo company behind an eSIM app for travellers, announced a Series C of about ¥5bn (about $31m) on 11 June 2026. The total combines ¥1.73bn in equity and ¥3.3bn in loans from financial institutions, according to the company's release on PR Times and a report in The Bridge.
Equity came from the Global Brain 9th Fund, the SMBC-GB Growth Fund and the ANA Future Creation Fund through a third-party share allotment. The lenders were MUFG Bank, Mizuho Bank, Shoko Chukin Bank, Japan Finance Corporation and Resona Bank. The release did not name a lead investor, and no valuation was disclosed. Cumulative funding after the round is about ¥6.3bn.
What Trifa does
Trifa launched its app in July 2021 and was founded on 17 November 2020. Users buy and activate eSIM data plans in the app, which covers more than 200 countries and regions without renting a WiFi router or swapping a local SIM. The release said cumulative downloads passed 2 million in 2026, and claimed the top position in downloads among domestic travel eSIM apps.
The company has been rolling out VPN, overseas travel insurance and airport lounge passes in stages. The Bridge also reported a sales partnership with Nippon Travel Group. Overseas customers account for about 10% of revenue, and the company started a global push in autumn 2025.
Masatoshi Kana is the chief executive and representative director. The release did not state a headcount.
What the money is for
The release lists four uses: new travel-related businesses beyond eSIM, such as payments and transport booking; expansion into East Asia and other markets; investment in AI, including AI agents designed to rebuild the user experience across a whole trip; and growth of the organisation and upgrades to existing products.
Kana framed the challenge as both economic, because of the weak yen, and psychological, because of the hassle of preparing for a trip. He said Trifa aims to become a platform that connects trip preparation to experience on the ground. The release's market context noted that about 18% of Japanese people hold a passport, citing Ministry of Foreign Affairs data.
Who invested
Global Brain's chief executive, Yasuhiko Yurimoto, said in the release that eSIM is essential for connectivity abroad, and cited the market's support for Trifa, the team's speed and growth in key performance indicators since the first investment as reasons for the follow-on. Yoshiaki Tsuda of ANA Holdings pointed to steady growth in domestic customers, overseas expansion and deeper ties with ANA, including mile exchange and employee business travel.
The release's quotes appear here in summary because the original is in Japanese. The release names the SMBC-GB Growth Fund, while one executive quote refers to SMBC Edge, a discrepancy the sources did not explain.
The funding so far
The release refers to a previous round without giving its size or date, so the history field is empty. With this round the company says total funding is about ¥6.3bn.
