Audiostock Inc. (TSE: 621A), the Okayama-based operator of the Audiostock sound-licensing platform, listed on the Tokyo Stock Exchange Growth Market on September 16, 2026. Creators upload background music, sound effects and voice-over tracks; the company manages the copyrights and sells access to businesses making video, advertising, games and broadcast content.
The business runs on two revenue lines. Licensing fees, split between three subscription tiers and single-track sales, brought in ¥880mn in the year to September 2025, while broadcast royalties collected through JASRAC and NexTone, alongside neighboring-rights income administered separately by bodies such as FMPJ and MPA, added ¥600mn. Combined revenue reached ¥1.51bn, up 70% from the prior year, and the operating margin swung to 25.3% from a loss of 15.3% two years earlier. The catalog holds more than 1.02mn sound sources and counts 40,000 creator groups and 203,000 user accounts; subscriptions make up 82.2% of licensing revenue, and monthly churn on the enterprise plan runs at just 0.5%.
For the year to September 2026, Audiostock guides for revenue of ¥1.75bn, up 16.3%, and operating profit of ¥444mn, up 16.6%, but expects net profit to fall 25.6% to ¥327mn. The company attributes the drop to a tax-timing effect: a one-off deferred-tax benefit booked the prior year unwinds, while rising taxable income pushes up the current tax charge. IPO proceeds of ¥87mn are earmarked for advertising (¥45mn) and recruitment costs plus annual payroll for new sales, customer-success, in-house development and internal-management staff (¥42mn). The company plans no dividend for the year.
