Four topics dominated Japan*s non-Twitter news cycle for the last quarter of 2017. Two involved sports: the signing of 23-year-old baseball superstar Shohei Otani to play for the Los Angeles Angels of the American League; and the resignation of sumo grand champion Harumafuji after assaulting a younger wrestler, which set off a three-way power struggle between headstrong stablemaster Takanohana, the Japan Sumo Association and a group of Mongolian wrestlers who currently dominate the sport.

The third was the Dec. 19 public debut of Xiang Xiang, the female giant panda cub born June 12 at Tokyo*s Ueno Zoo.

Then there was the 800-pound gorilla in the room, Kim Jong Un, dictator of the Democratic People*s Republic of Korea (DPRK), whose push for development of thermonuclear devices and long-range missiles to deliver them have raised tensions in East Asia to the highest levels in decades.
