Company profile
researched Aug 2026レターファン (Letter Fan) operates a Japanese web platform on which fans submit requests to talent, comedians and athletes for a personalized video message addressed to a single named recipient. A user browses individual talent pages, sends a request describing the recipient and the occasion, and receives the recorded video by email at the address registered with the account.
The site presents four principal use cases: advice or consultation, gifts for a significant person, messages of encouragement, and keeping the video as a personal keepsake. Alongside always-available individual talent pages, the platform runs time-limited event campaigns, including fan-club-restricted programs and lottery-based offerings, and charity campaigns in which proceeds from video messages are donated — for example a campaign directing sales to the Japanese Red Cross Society's Ukraine humanitarian crisis relief fund, and a campaign supporting children in Philippine slum districts who pursue baseball scholarships as a route out of poverty.
Operational terms published on the site define the delivery process: recording is intended to occur within 14 days of a request, and if the talent cannot record within that window the order is automatically cancelled and fully refunded, though limited-period and lottery campaigns are excepted. Requests are not guaranteed to be fulfilled, as talent may decline based on availability or request content. Buyers may cancel at any point before recording; after recording, returns and re-shoots are not offered. Delivered videos are licensed for wholly private use, with uploads to social media or other public showings prohibited absent specific permission.
Business model
Consumer marketplace intermediating between fans and talent: fans pay per requested video letter, which is recorded by the talent and delivered digitally to the requester. Campaign-based variants are run with sports clubs and fan clubs, and some campaigns are structured so that sales are donated to charitable causes.
Paid, per-request video messages purchased by consumers. Payment is accepted by credit card (VISA, JCB, American Express, Mastercard), with debit and prepaid cards also usable; orders that cannot be recorded within the stated window are refunded in full.
Traction
The site lists participating talent including judo Olympic gold medalist Tadahiro Nomura, swimming Olympic gold medalist Kosuke Kitajima, former Major League players Koji Uehara and Hisashi Iwakuma, Olympic rhythmic gymnastics representative Airi Hatakeyama, and comedians Kurochan, Hori and yutty, plus athlete Ayae Hakamada. Multiple campaigns have run with Nippon Professional Baseball clubs (Hanshin Tigers, Tohoku Rakuten Golden Eagles, Yokohama DeNA BayStars, Hokkaido Nippon-Ham Fighters) and J.League club Vissel Kobe, and the site publishes recipient interviews, including a video letter from Tadahiro Nomura to a young judo practitioner and one from former professional baseball player Tomoya Satozaki given as a job-start gift.
▸Full profile — market position, technology, go-to-market, geography
Market position
Positions itself around video messages addressed to "you alone" (あなた1人宛て) as private surprises and gifts, distinct from broadly published fan content, with distribution restricted to private use.
Emphasis on one-to-one, privately used video letters rather than shareable content; a 14-day recording window with automatic cancellation and full refund if unmet; and official campaign programs run jointly with professional sports clubs and their fan clubs, including charity-linked editions.
Technology
