Tsutomu Moriguchi's Akari is documented in Japanese specialist history as a yellow-white exterior-light line developed around 2014.

Overview

The recorded development concerns iterative yellow/white Miyuki selections; other yellow Miyuki programs by unrelated breeders must not be credited to Moriguchi.

Evidence labels refer to documentary strength. They do not assert independently tested genetics.

Known research gaps

  • Akari must not be conflated with independent yellow-Miyuki breeding histories at other farms.
  • Exact generation counts and first sale year require direct documentation.
  • Fish-specific genetic testing, validated inheritance percentages, exact water optima and universal grade thresholds have not been established from these cited histories.
  • Breeder-authenticated, licensed photos and individual parent provenance remain a separate editorial requirement.
