With the Summer Olympics coming to Japan in two years' time, some athletes are close to being ready for it and some still need a little more time to get into top shape.

Rikako Ikee is Japan's most rapidly improving swimmer and is unquestionably enjoying a moment right now. The 17-year-old had broken six national records, including short-course competitions, this year alone heading into the national championships.
