What determines the price

Three-color (red, white, black) color pattern balance
High
The more vivid the three colors (red, white, black) appear and the more evenly distributed across the body, the higher the ornamental value. If the coloration becomes too biased toward one color, the three-color character is diminished.
Wen development and uniformity
High
The more evenly the wen (hood) on the head develops, the higher the evaluation. Wen evaluation similar to that of ranchu is also applied to tosakin.
Tail form regularity and spread
Medium
Long, evenly spread tail fins enhance the characteristic appearance of this variety.
Black color (ink) clarity and stability
Medium
Verify whether the black (ink) coloration in the three-color pattern is stable. Black can vary with water temperature and season.

Appraisal points

Confirming three-color pattern balance

Good:: The three colors (red, white, and black) are vivid and evenly distributed throughout the body.
Caution:: When the three-color balance is disrupted—such as pale black or red appearing only in certain areas—the characteristic appearance of this variety is diminished.

Checking wen condition

Good:: The wen is evenly distributed across the entire head with minimal unevenness.
Caution:: If the wen develops only on one side or excessively covers the eyes, consider potential health implications.

Confirm health status

Good:: Swims actively, holds fins upright, and shows no signs of disease on the body surface.
Caution:: Individuals that sink to the bottom, show transparent fins, or exhibit bloodshot eyes require health assessment.
