“Sun-tama-tama” (a pun off of “Santama”, lit. “third Tama”) was a calico cat sent for training in Okayama. Sun-tama-tama was considered as a candidate for Tama’s successor, but the Okayama Public Relations representative who had been caring for Sun-tama-tama refused to give the cat up writing, “I will not let go of this child, she will stay in Okayama.” [25]
As of September 2018, Sun-tama-tama is working as the stationmaster in Naka-ku, Okayama and appears occasionally on Tama’s Twitter account.
