  Hirano Kotoken founder Ryoji Hirano (1910-1988) had started an independent antique shop in Osaka on 26th Feb, 1938, after having been educated for 7 years under Mr. Umekichi Asano(*1), a great expert in Asian antique.
Ryoji had acquired an invaluable knowledge and experience from Mr. Asano, and he had also traveled to China many times in 1930s.
After independence, having supported by Hakuturu Museum, the Sumitomo family, Baron Fujita and private international collectors/museums, he went on to earn the respect and trust of the collectors, as well as of dealers and scholars.
