With four athletes in the Open class and two in the Paralympic class, Japan took presence once more in the World Trail Orienteering Championships, being one of the eight “totalistic” nations so far, scoring a constant presence throughout the event's thirteen editions (the others nations are Finland, Great Britain, Lithuania, Norway, Russia, Sweden and the United States). Japan's performances were modest this year but the fact of taking two athletes to the TempO Final - as happened in 2013 and in 2015 – deserves to be highlighted.
+ Finishing the TempO competition in the 20th place, Tatsuyoshi Koizumi matched the best result ever of a Japanese athlete in this competition, side by side with Toshihumi Yoshimura (Vuokatti, Finland 2013).
- Back to the World Championships after a break of five years, Yusuke Okubo was out of the TempO Final and finished the PreO race, Open Class, in the 56th position. A good performance in the Relay isn't enough to hide a quite modest presence overall.
