Thirty hand-selected Omosako male Shiro Utsuri. One year. Growers across America. Judged by the Omosako family themselves. Pick your style, raise your fish, and find out what you can do.
We've taken a special release of young Omosako male Shiro Utsuri and sorted them into four honest categories. You choose the category that suits how you like to grow — we send you one fish from that group. Raise it for a year, document the journey, and submit photos & video for online judging.
Four styles to choose from below. You receive one koi from the group you pick — no cherry-picking, every grower gets a fair shot at a great fish.
Your pond, your water, your food, your skill. A full year to develop your Shiro Utsuri's sumi, skin, and body.
Share photos and video as it develops. Build your grower profile and trade notes with the rest of the field.
Submit your final photos & video. The Omosako family reviews every entry and crowns the winners.
Choose one of four categories below — we send you a koi from that group. Grow it out for a year, then submit photos and video. The Omosako family crowns the winners.
Each category holds about 7 koi. You'll receive one fish from your chosen group, selected by our team.
Finished koi with their black already up. What you see is largely what you get — clean, show-ready Shiro Utsuri for the grower who wants to start strong.

8Can't choose? Take one koi from all four categories and grow a complete stable. The most fun way to play, and the best value in the contest.
At the end of the grow-out, every grower submits final photos and video. The fish are judged on development, skin quality, sumi, body, and overall finish — the way it would be at a Japanese show, by the very family that bred them.
Every category winner takes home premium JPD nutrition — and the overall champion's koi earns the feeder to keep the gains coming.
