Tan Long Group has partnered with Japanese and Korean counterparts to develop an onshore tuna farming project aimed at securing supplies of premium seafood as natural catches decline, according to Nikkei Asia. Tokyo Kiraboshi Financial Group is coordinating the initiative between Tan Long Group and MegaPlan, a Korean technology startup. The alliance plans to build land-based tuna farms and develop distribution networks for international markets.
Onshore tuna farming is positioned as a response to the long-term contraction in wild tuna availability. Global tuna catch has fallen by 74% over the last four decades, and the species is at risk of depletion by 2050 if sustainable alternatives are not scaled.
The project’s technical core is MegaPlan’s farming technology. The startup reportedly holds exclusive know-how for year-round artificial breeding of tuna in controlled environments, which differs from traditional approaches.
The land-based model is designed to reduce environmental risks, including microplastic pollution, rising sea temperatures, and natural disease. MegaPlan has also demonstrated commercial viability: it achieved a successful harvest and sold the first batch of artificially bred tuna on Jeju Island in early 2025.
The collaboration underscores the role of financial institutions in connecting high-tech agriculture with industrial execution. MegaPlan’s deal is reported to have been facilitated through BNK Financial Group, a major Korean financial institution that has a strategic partnership with Tokyo Kiraboshi.
Investment in high-tech aquaculture is part of Tan Long Group’s broader expansion across its agricultural ecosystem. By 2025, Tan Long is described as a multi-sector company with tens of trillions of VND in revenue, including a leading position in grains under the A An brand and pig farming through BaF Vietnam (ticker: BAF), as well as a high-tech machinery maker, Siba (ticker: SBG).
The group also operates a modern rice processing and distribution network of about 70,000 points nationwide. Through the alliance, Tan Long is expected to leverage existing infrastructure to integrate MegaPlan’s technology.
Tokyo Kiraboshi Financial Group manages assets of around 6.8 trillion yen and operates more than 150 branches as of the end of fiscal 2025.
MegaPlan, meanwhile, recently completed a Pre-Series A round led by Bluepoint Partners in late 2025. The startup’s stated goal is to pursue a vision of “one-dollar tuna,” aiming to make high-quality tuna more accessible through end-to-end digital processes from breeding to retail.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
