Is Tokyo a Good BQ Course?

Published October 4, 2026 · Estimates, updated each registration cycle

Short answer: yes. Tokyo is one of the fastest major marathon courses in the world, and the 2027 edition on Sunday, March 7, 2027 falls inside the qualifying window for the 2028 Boston Marathon, which opened on September 19, 2026. It is a certified World Marathon Major, it loses a little height from start to finish rather than gaining it, and early March weather in Tokyo is usually cool. A Tokyo result counts at full value on a Boston application. The hard part, as with London, is getting a bib in the first place.

What the course looks like

The race starts beside the Tokyo Metropolitan Government Building in Shinjuku and finishes on the broad avenue in front of Tokyo Station. In between it heads east through Iidabashi, makes a series of out and back legs toward Shinagawa, Asakusa and the Kaminarimon gate, passes through Ginza more than once and swings out to the east side of the city before turning back toward the finish. Course guides describe total elevation change of only a few dozen meters, with the start sitting roughly 35 to 40 meters higher than the finish. Most of that drop comes in the first five kilometers out of Shinjuku. After that the route is close to flat, with a few short bridge and underpass rises in the final 10 kilometers that feel bigger than they are on tired legs. The net drop is nowhere near the 1,500 foot level where Boston starts adding time, so the downhill adjustment does not touch a Tokyo result. For the courses it does affect, see which marathons are too downhill.

Weather and the turnarounds

Early March in Tokyo typically brings a cool, dry morning, often in the 40s Fahrenheit at the start, which suits fast running. Rain and a cold wind off Tokyo Bay show up in some years, and the open stretches near the water are where it bites. The other thing that costs time is the number of 180 degree turnarounds. Each one breaks your rhythm and adds a few seconds of braking and reaccelerating, and with a field of around 40,000 runners the turns can bunch up. Take them wide if the crowd lets you, and do not sprint back up to pace afterward. For how warm race days have shifted past Boston cutoffs, see weather and cutoffs.

The real obstacle: getting a bib

Tokyo does not use qualifying times for most runners. The general entry is a ballot with reported odds of roughly one in ten, and the draw for March 2027 has already taken place. The remaining routes for most overseas runners are charity entries, which carry a sizeable donation, and packages from official international tour operators. There is a small semi elite route with standards far faster than any Boston time. If you do not already hold a Tokyo place, do not build a 2028 Boston plan around it. The access gap is covered in Boston vs Tokyo entry.

The number to actually aim at

Running the standard is not enough. The 2027 Boston race cut at 5:17 under the standard, after 4:34 for 2026. Nobody knows the 2028 cutoff yet, so any target is a planning number, not a forecast. Take a 50 year old man, standard 3:20:00. With a planning buffer of 6:00, above both of the last two cutoffs, he would aim for 3:14:00. That is 4:36 per kilometer, the unit Tokyo marks the course in, or 7:24 per mile, reaching halfway in about 1:37:00 on an even split. Because the opening five kilometers run downhill, hold goal pace there instead of banking time you will need later. Tiers for every age group are in what time you need for Boston 2028.

A note on timing and travel

March 7 comes six weeks before Boston on April 19, 2027, so a runner who already holds a Boston 2027 bib should treat Tokyo as either a goal race or a long run, not both. For a runner chasing 2028, an early March qualifier leaves plenty of room for a spring or fall backup inside the 2028 qualifying window. Flying in from the United States means a large time zone shift, so arrive several days early. For another flat major with a much easier entry, compare is Berlin a good BQ course.

Verdict

Tokyo is a good BQ course: certified, fast, gently downhill overall and usually run in cool weather, with superb organization. Its costs are the turnarounds, long travel and, above all, a ballot most applicants lose. If you have a place, it is a strong day to bank a buffer. Before you pick a goal, enter your age, gender and target time in the cutoff predictor to see how that buffer would have done against every real Boston cutoff since 2014.
