We’ve recently added four new Japanese Koi to our collection, each selected for quality, character, and potential. Sourced from respected breeders in Niigata, Japan, these koi offer a mix of classic varieties and more unique, developing types—ideal for both hobbyists and experienced keepers.
Below is an overview of the latest arrivals and what makes each one stand out.
Black Diamond Koi – Takatatsu (EK6993)
41cm Nisai – Doitsu Ginrin Kumonryu

This Black Diamond is a striking example of a Doitsu Ginrin Kumonryu, combining a clean scaleless body with reflective “diamond” Ginrin scaling along the dorsal line.
The deep sumi pattern contrasts against lighter tones, creating a bold and modern appearance. Like many Kumonryu types, this koi is expected to change over time, with pattern shifts adding long-term interest.
A strong choice for keepers looking for something dynamic and slightly different from traditional patterned koi.
Aka Bekko – Hosokai (EK6982)
20cm Tosai – Classic Bekko Pattern

A simple and traditional variety, this Aka Bekko offers a clean red (Hi) base with well-placed black (Sumi) markings.
Bekko are appreciated for their minimalism, where pattern balance is key. This koi provides a nice example of evenly distributed sumi without overcrowding the body.
Ideal for hobbyists looking to build a balanced pond with classic Japanese varieties.
Ki Matsuba / Asagi – Hosokai (EK6983)
23cm Tosai – Developing Reticulation

This koi brings something more subtle to the collection, featuring a warm yellow (Ki) base with early-stage reticulation forming across the scales.
With influences from both Matsuba and Asagi varieties, the net-like pattern is expected to develop further as the koi grows, adding depth and definition over time.
A great option for those looking to introduce softer tones and understated detail into their pond.
Kujaku – Hosokai (EK6984)
21cm Tosai – Metallic with Reticulation

A vibrant and eye-catching Kujaku, combining a bright metallic base with strong red (Hi) patterning and developing net-like scale definition.
The reflective quality of the skin gives this koi a standout presence, particularly in clear water and natural light. As it matures, both the colour and reticulation are likely to become more pronounced.
A solid addition for anyone wanting to add brightness and contrast to their collection.
Choosing the Right Koi for Your Pond
Each of these koi offers something slightly different:
- For movement and change: Black Diamond (Kumonryu type)
- For classic simplicity: Aka Bekko
- For subtle development: Ki Matsuba / Asagi
- For brightness and impact: Kujaku
When selecting koi, it’s worth considering not just how they look now, but how they will develop over time. Young koi (Tosai and Nisai) in particular can change significantly, which is part of what makes koi keeping so rewarding.
