I found that Yaeyama region of Okinawa has a cutest cat mascot character who named Pikaryaa.
He (Pikaryaa is a legendary wild big cat boy!) is not only a mascot character but sightseeing and advertising manager of Yaeyama region. He has some spots on his tummy, these are very looks alike Yaeyama islands.
We could find him everywhere in Ishigaki island or Yaeyama region islands.
I got his ball-point pen as a souvenir for myself.
