University Emblem

In 1980, the University of the Ryukyus adopted its official emblem, which had undergone minor modifications since the university’s establishment in 1951. Professor Chosho Ashitomi and designer Kaoru Miyara were responsible for the final design upon commemoration of the university’s 30th anniversary.

At the heart of the emblem is a combination of leaf of the basho plant, or Japanese banana (or Musa basjoo in scientific name) and a pen quill. The leaf symbolizes nature and cultural traditions of the Ryukyu archipelago, and the pen quill symbolizes academic inquiry and freedom. The combination of the two in a circle represents peoples’ harmony and the universe.
