Philatelic Week Issued on Jul.1, 1965 (Showa40) Okinawa stamps Hobby Weekly stamps are often designed with crafts that have been handed down from ancient times in Ryukyu, and in 1965 (Showa 40), the ancient Ryukyu stringed instrument "Jabisen" was designed. The snake skin line started in the yuan of China, was transmitted to Okinawa at the end of the 14th century, and was transmitted to Sakai and Hakata at the end of the Muromachi period (1558-69), and changed to the shamisen. Put a snake skin on the body of the instrument, and play with three strings and square claws. This stamp was distributed with 2000 overprints.
