Key Point ① The selection battle toward Los Angeles
The Tokyo Marathon is an eligible race for earning a spot in the “Marathon Grand Championship (MGC),” Japan’s Olympic selection pathway.
The fight for top Japanese placement and hitting the qualifying standard can directly shape the next phase of the national-team race.

Thanks to a flat course and typically stable weather, the Tokyo Marathon is known as one of the world’s fastest races.
If the opening half goes out aggressively, it could set up a race for a course record and other standout times.
Key Point ③ Will a new Japanese ace emerge?
In recent years, Japanese men’s marathon running has been in a period of generational transition.
How long Japan’s top runners can stay attached to world-class pace—especially after 30 km—will be a key marker of performance and evaluation.
