Yamada Suisan began the world's first general-consumer trial sale of fully cultivated eels in Tokyo on Friday [1].
This development marks a significant shift in the eel industry, which has historically relied on the capture of wild juvenile eels. By producing eels from egg to adult, the company aims to create a sustainable supply chain that protects wild populations from overfishing.
The trial sales took place at a store in Tsukiji, Tokyo, while production is managed at Yamada Suisan facilities in Saiki, Ōita Prefecture [1, 2]. Each frozen kabayaki eel was priced at 4,500 yen [1]. Due to high demand, the company offered a limited quantity of 45 packs [1]. One customer said they waited nearly four hours to purchase the product [1].
Achieving full cultivation is a costly process. Current production costs are approximately 2.5 times higher than those of normal eel farming [1]. To address this, Yamada Suisan is expanding its infrastructure. The company currently operates 12 rearing tanks and plans to increase that number to 57 [3].
Scaling production is the primary hurdle to making the product affordable for the general public. The company has set a target to produce 100,000 fry by 2028 [1]. A customer who purchased the eel said they hope it becomes more affordable and spreads throughout the world [1].
Another customer described the purchase as holding something historical and said they finally felt the reality of the achievement [1].
“The world's first general-consumer trial sale of fully cultivated eels began in Tokyo on Friday.”
The transition to fully cultivated eels represents a move toward food security for a luxury item prone to environmental volatility. While the current price point remains a barrier for the average consumer, the expansion from 12 to 57 rearing tanks suggests a shift from laboratory-scale success to commercial viability. If Yamada Suisan meets its 2028 target of 100,000 fry, it could significantly reduce the ecological pressure on wild eel migrations.
