Marudo Koi Farm - Achievement and Success


Being the third generation farmer of the Marudo koi farm, Toshihiro Hirasawa is taking the farm to the next level of success. He is following his father's principle of producing beautiful Koi varieties. Their exports to foreign countries have recently grown at a rapid pace, and presently, as much as 90 percent of their production is exported, with the EU and China being primary destinations for their fish. Their annual koi production is also rapidly increasing as a result of their hard work.


It is important to note that foreign farmers are also making strides to increase their output and quality. This makes international competitions more and more competitive and requires a keen focus to produce first-rate Koi that clearly identify them as genuine Japanese Nishikigoi.
