Bringing Nishikigoi Closer to You

Organised by Hana Koi Village
The ‘Matsunosuke Project’ Takes Place

On Saturday 18 July, the second instalment of the ‘Matsunosuke Project’—a koi-rearing experience held in collaboration with Toshiyuki Sakai, one of the creators of the renowned ‘Matsunosuke’ bloodline—took place at a group of mud ponds in Hirano, Kakimachi, Nagaoka City, Niigata Prefecture.

This project is scheduled to run from mid-June to early December, comprising a total of seven sessions covering activities such as fry selection, Ikeage and visits to Koi farms. Programmes have been designed to be enjoyable for beginners wishing to take up a hobby in Nishikigoi, as well as for families.

The project is planned and organised by Single Support Co., Ltd. (Representative: Shinji Sugita), headquartered in Shibuya Ward, Tokyo, which carries out Nishikigoi-related projects under the name Hana Koi Village. Mr Yasuhiko Hashimoto, the project manager, has been involved in the Nishikigoi industry for over 50 years as an enthusiast and has witnessed its evolution first-hand.

“As Yamakoshi was close to my mother’s hometown, I developed a deep affection for both the area and Nishikigoi. Later, having experienced the Chuetsu Earthquake, I felt a strong sense of responsibility to contribute to the regional revitalisation of Yamakoshi and to preserve the Nishikigoi culture.”

On this day, blessed with fine weather, a selection experience was held for Kohaku and Taisho Sanshoku fry born in spring. Once the fry, which had grown to around 5 cm, were scooped from the Mud ponds, participants received a personal briefing from Mr Sakai on the key points of selection and the fish’s future potential, before scooping them up one by one with nets, their eyes fixed intently on the task.

In addition, an event titled ‘The Life Project’ was held, where participants could take home free fry that had not been selected during the sorting process. ‘Even though this is the second round of selection,’ said Mr Hashimoto with a smile, ‘the potential of these fry is still limitless. You might just discover an unexpected treasure.’ It is also reported that other events are being planned, such as ‘Friendly Pond’, a spot sale where participants set their own prices.

Meanwhile, he explained that this programme is not merely a recreational activity; its aim is to accurately pass on to the next generation the artistic and cultural value inherent in Nishikigoi—such as the beautiful Shiroji and Beni quality established by the founder, Matsunosuke—and to foster an environment for nurturing young talent to this end.

‘By creating an environment in which the legendary Toshiyuki Sakai, now in his eighties, can once again devote himself to his passion, we hope to establish a system whereby the next generation of breeders can inherit his exceptional skills and spirit, and eventually strike out on their own,’ said Mr Hashimoto.

Making the most of the experience and network of contacts he has cultivated through his work in regional revitalisation, he spoke with a determined gaze, stating, “This is my final challenge,” as he set his sights on rebuilding the foundations of the Nishikigoi industry as a proud part of Japan’s traditional culture.

The next event, scheduled for Saturday 10th and Sunday 11th October, will feature a hands-on Ikeage experience of catching Tosai Nishikigoi from the pond, with the opportunity to purchase the fish on the spot. Please check Instagram for details regarding participation fees and other information.
