Now in its 16th year this one week of koi classes with the masters here in Niigata is not to be missed.

“We have over 35 years of experience buying and supplying Japanese koi around the world. Working in Ojiya, Niigata 365 days of the year has allowed our business relationship to form a long term friendship with the breeders and this allows you access to the best koi at the best prices. 

Whether you come with us for 1 day, 1 week or longer to buy Koi, or join us on one of our Koi masterclasses or on one of our tours, you will quickly realise why JKX can be the best partner for you as a hobbyisit or for your business. In Japan we call it “Yukuri, yukuri,” which means “slowly, slowly”. I want your association with us to grow slowly. I look forward to welcoming you to Japan.” Martin Symonds

Our unique koi Buying Trips start from February until June and then from October until December each year. These personal bespoke trips are catered to your requirements.

Koi Masterclass started in 2000 and now in its 16th year these classes are held with some of the leading breeders here in Niigata.

Japan Koi Export (JKX) is a well-established company based in Ojiya City, Niigata, which is the heartland of Japanese Koi.
Martin Symonds formed JKX so that he could bring the very best koi from Niigata to customers at the very best possible prices, or “farm prices” as Martin calls it.  For 35 years he has been buying and shipping Japanese koi around the world. JKX are not agents, or ‘middle men’ who visit the area a couple of times a year. René Villela, (Martin’s associate) is based in Ojiya, Niigata and works closely side by side with many of the breeders. Martin himself has lived in Ojiya for 12 years.

We specialize in supplying koi, whether personally selected by you here in Japan, or by selecting from our Spring Console price List, via this website or through our website at www.exclusivejapanesekoi.com


Launched in 2016, Exclusive Japanese Koi is a dedicated website offering koi from some of Niigata’s leading breeders.

The breeders have their very own individual pages which gives them an opportunity to include and show you, (the customer),
a range of their koi, whether it be show koi, high quality koi or koi listed on our Spring Console List. New koi and special offers will be updated on the site on a weekly basis.

JKX’s long-term close friendship and business relationship with the breeders gives a unique inside knowledge to the best koi available. Over the years, customers of JKX’s have come to appreciate this close relationship, and therefore many customers return year after year.  For the customer to be satisfied is something JKX strive for – something that is also the “Japanese Way”.

Whether you come on one of our Buying Trips, Koi Masterclass or one of our tours, we feel that JKX can be your Gateway to Niigata Koi.

We hope you will enjoy using this site and that you will find it helpful.  This website covers all aspects of what our company has to offer. Both Martin Symonds and René Villela very much look forward to welcoming you to Japan.
