Overview
This line was important breeding input for other breeders' later colorful lame experiments. The first development and any later selection program must retain separate creator attribution. Documented developer/creator role: Toshihiro Wada / 和田敏拓.

Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Recorded lineage inputs
Yang Guifei Hikari Daruma / White Miyuki (F5 selection)
These are historical breeder-reported founder inputs or longer selection stages, not individually sequenced parents. Review the source W01 for its original scope and missing generations.
Known research gaps
- F5 is a reported selection-stage designation, not a fixed color inheritance percentage.
- Do not assign Wada founder credit for every later black/colored lame descendant created by JOURAKUAN.
- DNA-confirmed ancestry, Mendelian segregation, complete parent-pair registers and strain-specific water requirements are not established.
- Images from magazine, breeder sites and shop listings are not republished without verified reuse permission.
