Accounts of the Kawano selection’s discovery chronology differ. Hodgson’s 1967 account says a limb sport was found in an Oita orchard around 1905. A 2025 RyuKoch article says Amanatsu was discovered in Tsukumi, Oita, in 1935, citing Wikipedia. The precise discovery date and relationship between these accounts remain unresolved.
