Treportal, a Tokyo start-up behind an app for trading fan merchandise, raised about ¥67m (about $0.43m) in a round it called a pre-Series A, it announced on 29 September 2026. The company said the financing, a third-party allotment of new shares, was carried out in August.
Chiba Dojo Fund led the round. The Co-Founder Fund of Prime Partners took part, as did an individual investor who founded the AI education company Aidemy and is a managing director at Accenture in Japan. Treportal did not disclose a valuation. The Japanese startup database INITIAL lists the round as a seed round.
What Treportal does
Much fan merchandise in Japan is sold as random goods: buyers pay for a sealed pack or capsule without knowing which character or member they will get. That leaves many fans with duplicates and items they do not want, and trading has largely taken place between individuals on X.
Treportal's app lets fans search for the items they want, keep track of what they own, and trade or sell them. It uses its own merchandise search system, preset trade messages and anonymous exchanges to make the process simpler and safer, the company said. Its users are concentrated in genres where random goods are common, including VTubers, K-pop, games and anime.
The company said the app had about 15,000 monthly active users and around 5,000 posts a month. Its co-founder and chief marketing officer said more than half of posts led to a completed trade and that the app had grown with almost no spending on advertising. The company also runs Say Cheese, a map of fan-activity spots such as events, cafés and pop-up shops, according to INITIAL.
What the money is for
Treportal said it would use the funds in five areas: sponsoring events and live shows and testing in-person trading spaces near venues; partnerships with rights holders, talent agencies, merchandise retailers and event organisers; testing business uses of its fan map, such as advertising and surveys; product development and hiring engineers; and marketing.
The company also pointed to the data it collects on which items fans want and which they want to give away, which it said could show rights holders where demand lies.
Who is behind it
Treportal was founded in October 2023 and is based in Minato, Tokyo. Its chief executive and founder said the idea for the app came from trading merchandise personally and running into the risks of dealing with strangers on social media. According to the release, the company plans to widen the app into a broader tool for fans, covering information, inventory and schedule management and communication, and to serve overseas fans of Japanese content, starting with visitors to Japan.
A general partner at Chiba Dojo Fund said in the release that the founders' own experience as users was evident in the app and that the fund saw a real culture of trading among fans.
The company did not report its headcount or any earlier funding.
