As the medaka boom has expanded, shows and exhibitions are now held across Japan. Shows are venues where breeders compete to display the most beautiful medaka, while exhibitions and sales events serve as gathering places for medaka enthusiasts to connect and share knowledge. There is no need to feel intimidated even as a first-timer. This article covers everything from major medaka events and entry procedures to judging criteria and tips for enjoying these gatherings.
Major Medaka Shows and Events
Medaka events across Japan come in various formats including competitive shows, exhibitions, and sales events.
Japan Medaka Association Grand Championship: The most prestigious show, organized by the national medaka enthusiast organization. Outstanding medaka from across the country are entered
Medaka World: Large-scale sales and exhibition events held in various locations. Famous breeders set up booths where rare varieties can be purchased directly
Roadside station and home center sales events: Community-based medaka sales events. Accessible for beginners and great for meeting local breeders

Online social media shows: Online shows held on Instagram and X (Twitter). Participate from anywhere and connect with breeders nationwide
Local club monthly meetings: Small-scale shows held monthly by regional medaka clubs. Ideal for beginners to gain experience
Shows are primarily held from spring through autumn, with large events concentrated during summer (June-September) when medaka colors and metallic luster are at their peak.
Understanding Show Judging Criteria
Medaka shows judge how closely each fish matches the ideal standard for its variety. Here are the common basic judging points.
Body shape: Does it conform to the variety's standard body type? No spine curvature or body distortion. Bilateral symmetry is emphasized

Color vibrancy: How intensely and clearly the variety-specific colors are expressed. For tricolors, the contrast of red, white, and black; for Miyuki, the strength of external luster
Pattern balance: For patterned varieties like tricolor and kohaku, the distribution of color patches matters greatly. Symmetrical, evenly distributed coloring from head to tail is ideal
External luster and lame quality: For Miyuki and lame varieties, the intensity, uniformity, and coverage area of the shine are evaluated. Full-body luster and high lame density are preferred
Fin shape and condition: Are fins intact without tears or splits? For some varieties, fin shape itself is judged (long fin, swallow types)
Size and health: Proper size for the variety. Neither too thin nor too fat. No signs of disease is a prerequisite
Swimming behavior: Is the fish swimming actively? Fish swimming at an angle or sinking to the bottom receive deductions
Judging criteria vary slightly between shows. Check the organizer's published criteria before entering.
Preparation Schedule and Entry Methods
Medaka entered in shows require planned preparation starting months in advance.
3-6 months before: Select candidate fish. Pick individuals that best express the variety's characteristics and begin dedicated management in separate containers
2-3 months before: Feed color-enhancing and high-nutrition food to develop coloring and condition. Promote external luster and lame development with sunlight exposure
1 month before: Final selection of entry fish. Submit competition registration. Prepare transport containers and ice packs
1 week before: Final inspection of entry fish. Check for fin tears and surface injuries. Perform water changes to ensure clean conditions
Day before: Reduce feeding (to prevent water quality deterioration during transport). Prepare transport water and match temperature
Day of: Place medaka in oxygen bags (breeder bags), transport in insulated bags with temperature control, arrive at the venue early, and complete registration
Entry fees vary by show but typically range from 500-1,500 yen per entry. Events are divided by variety category, so confirm which category your medaka belongs to in advance.
Enjoying Sales Events and Markets
Even without entering a show, sales events and markets offer plenty of enjoyment. The thrill of discovering rare varieties and connecting with breeders is the main attraction.
Research in advance: Check the social media of breeders attending the event to see if your target varieties will be available
Bring cash: Not all vendors accept electronic payments. Bring sufficient cash in small bills
Arrive early: Popular varieties sell out quickly. Arrive early to secure the best individuals
Bring transport supplies: Prepare insulated bags, small containers, and battery-powered air pumps for safely taking fish home
Talk with breeders: Sales events are valuable opportunities to hear care tips and breeding advice directly from breeders. Do not hesitate to ask questions
Getting Started Without Showing
You do not need to compete to enjoy medaka shows. Attending as a spectator is a great way to learn about varieties, deepen your knowledge, and make connections in the hobby community. Many hobbyists begin by observing shows and gradually work toward entering their own fish.
On BriChoku, you can purchase show-quality medaka directly from competitive breeders. Breeders who regularly participate in shows raise fish to the highest standards, so you can obtain excellent individuals to start your own breeding program.
