Welcome to Causeway Koi - selling quality Japanese koi and pond products to the UK and Ireland.

We prefer that, where possible, you place your order here on our website, or over the phone. If you prefer to come to the shop, then please practice social distancing. We want to stay open as long as possible so that we can continue to serve you, so please help us in this way.
The shop is open during our regular hours (see bottom of page) and all day during Bank Holidays. There is no need to book an appointment.

We trust you find what you are looking for. If there's something you need, but it isn't listed, please contact us. We may already have it in stock or be able to get it for you.

Our koi are quarantined and subject to strict health controls. Causeway Koi is a registered APB (Aquaculture Production Business), which means we follow EU regulations allowing us to send our koi legally to customers in S. Ireland. You can buy from us in confidence.

All our koi come directly from Japan and are fully legal and documented. We can deliver koi on a 24hr service (Ireland only). Dry goods are usually delivered next working day to Ireland (orders placed before mid-day).

All our koi come from the Niigata prefecture of Japan. We make regular buying trips there and have built great links with the breeders, ensuring you get the best fish at the keenest prices.

The 2021 fish are available, in the shop and online. All available nisai and most remaining tosai are online.

We can send our koi anywhere in Ireland. Remember, there is no charge for delivery of any order across Ireland, which is over £60. Smaller orders incur a £5 charge.
We no longer send orders outside Ireland.

You can follow our trips and see pictures of the koi being purchased in Japan on our Facebook page HERE.

Our fish and dry-goods can be purchased on-line or by calling Wesley on 028 70825213.
You can purchase our Gift Certificates online at any time and choose between self-print or posted.

Causeway Koi supply quality Japanese Koi to suit every budget.
We have a huge range of stock in-store. If you don't see what you need here, please contact us.

For all your pond and fish requirements it has to be Causeway Koi!
