Japanese group General Oyster, specialised in oyster production and distribution, will invest ¥800mn ($5.1mn) to accelerate its solar energy development. Listed on the TSE Growth market, the company will divide the investment equally between resale projects and self-operated installations, as part of a strategy to stabilise its expansion in the renewable energy sector.
The move builds on the activities of its subsidiary GO Store, which began reselling photovoltaic projects in 2024. Despite operating in a growing market, the subsidiary had not fully captured opportunities with larger clients due to limited resources and a weak credit profile. General Oyster is now aiming to reinforce its position in a rapidly evolving sector.
An even allocation between resale and generation
To support its resale business, General Oyster plans to invest in around 30 solar projects of 110kW each, with a unit cost of approximately ¥13mn. These projects are designed to remain under the 50kW alternating current threshold to benefit from low-voltage grid access. The company targets a 9% gross margin and expects to allocate ¥250mn to this segment by the end of November 2025.
At the same time, the company intends to build a portfolio of 33 photovoltaic plants of 100kW each, at an estimated cost of ¥12mn per unit. Each project is expected to operate for 30 years, with an initial sales price of ¥14 per kilowatt-hour.
A long-term profitability lever
Over their lifetime, General Oyster anticipates around ¥1.1bn in gross profit from the owned assets. While the company has not disclosed specific monetisation details, it is likely to rely on Power Purchase Agreements (PPAs). This marks a significant shift for a company historically focused on hospitality and aquaculture.
Founded in 2000, General Oyster reported consolidated revenue of ¥3.7bn in fiscal year 2024. Its renewable energy segment did not generate any sales but held ¥85.7mn in assets at year-end.
