Overview
- The complaint was sent to the Osaka District Court on Nov. 5–6, alleging improper asset management by Toshi Soken Invest Fund, and the parent company says it will respond once it is served.
- Plaintiffs come from 46 prefectures, range from their teens to their 90s, and mostly invested in the flagship Series Narita between June 2019 and July 2025.
- Distributions for all Series Narita products have been delayed since July 2025, and some investors who canceled or reached maturity report that refunds have not been returned.
- Company president Kenichi Yanase apologized in an August video, attributing payment delays to Osaka Prefecture’s 30‑day partial business suspension issued in June 2024.
- The product has reportedly raised about ¥200 billion from roughly 38,000 investors, and plaintiffs’ lawyers say additional collective lawsuits are planned.
