In a race with over 32,000 entrants one would expect some glitches... unless the race is held in Japan. Wonderfully organized, and with 1000s of incredibly friendly, helpful volunteers this is an awesome event. Packet pickup on the Friday was a breeze, the course is flat and fast, and we had perfect running weather and a course lined with cheering crowds. Plenty of water stations, porta-potties and entertainment along the way. My info packet didn't arrive on time, which was no problem as I emailed race officials and received via email my bib certificate within 24 hours. I was concerned about running with so many people and was expecting chaos, but I am astounded by how smoothly everything went. I only speak a few words in Japanese but language really was no problem. I do believe priority is given to foreigners, as over 300,000 people entered and both myself and a friend from New Zealand were accepted. And, of course, you have all of Japan to visit and can get in some serious skiing! Many thanks to Tokyo!!

Despite the horrendous weather, the organizers put together a terrific large marathon, comparable to Chicago and Boston. The expo was huge, with plenty of useful freebies. Start and finish lines were easy to get to, and through. My only complaint on the course was the lack of variety - the first 25 miles were totally urban, running along major streets. Good crowds and adequate toilets. Only the last mile over the bridges of Tokyo Bay brought some variety. Highly recommended for the international traveler.

It's probably the biggest marathon in Asia, and it's superbly organized.

Everything for me was hitch-free, from the bib pick-up to the actual run itself. The expo was pretty good, and there is quite a bit of stuff that you can only get in Japan.

The weather wasn't that great. It was cold (in the single digits, Celsius), and it was raining most of the way. Coming from a tropical country, it was quite hellish for me.

Toilet breaks were mad, as there were long queues at every stop until about 20K in. I guess that's quite expected when you have 32,000 full marathoners running in cold rain.

No point looking for a bush, as the streets were packed with well-wishers and supporters looking out for their friends. I got the impression that everyone would rather die from a full bladder than pee in a bush somewhere.

But overall, it was a great course - flat most of the way with a couple of bridges at the end. There's a bit of wind in some areas, but nothing too serious. For the sightseeing runners, it passes some of the major attractions like the Imperial Palace, Asakusa, Tokyo Towers and Ginza, so there's something to see most of the way.

If it were only a couple of degrees warmer....

This was an absolutely amazing experience: an interesting, totally traffic-free course lined all the way with lively spectators, exemplary drink and food stations, really helpful volunteers and perfect organization, from registration, to baggage handling, to the finish area (with huge cedar-troughs for a foot bath!). There were 216,000 applications this year, but foreigners are given preferential treatment. If a marathon in Asia is on your list, this should be it!

Asia's biggest marathon did not disappoint. While there is a lottery system for entry, it's an unwritten rule that they accept all international applicants. Race expo was well organized, and about as large as that of NYC. Race day was cold and rainy, but there were still lots of fans on the course (the course is all through the city, so fans lined the entire 42.2 KMs). They weren't as loud as fans in NYC, but showed spirit nonetheless. Course is very flat with only a few mild inclines in the late KMs. No wave start, however, so a little crazy getting to the start area (~32,000 runners). Excellent signage on course for water stations, toilets and KM markers. If you run one marathon in Asia, it should be Tokyo!

Very well organized, with tons of smiling volunteers. The course is like a sightseeing tour of Tokyo, with big crowds, taiko drums, geisha dancing, and brass bands. A real festival atmosphere.

I have done 57 marathons so far, including every major international marathon in the world. None of the others even come close to Tokyo. I ran the first Tokyo Marathon in 2007, the inaugural one, and expected it to have some glitches. The organization was absolutely perfect! It was an unusually cold and rainy day, and probably a million Japanese men, women and children still lined the entire course. And what a course it is! I am a New Yorker, and I love New York, but I have to admit that the New York City Marathon has quite a few boring patches. In Tokyo you run through all of the most interesting sights of the city. There is not a single boring minute, with the possible exception of the last mile, when you are running over a flat bridge. Even then, the only supporters allowed are fantastic (though they are merely the very vocal guys and girls at the water stations).

The expo was great, the start was great, the finish was great, the course was great, and the entire experience was simply terrific. I never run the same marathon twice, but if I ever break my rule, it will only be for Tokyo!

Go for it!!!

The whole day was very efficiently organized. There were no long waits at the start or finish, unlike the only other similar scale marathon I've done (New York). The roads are very wide, so it's easy to pass people at the start and the crowds are enthusiastic. My one complaint would be that there is very little in the way of support past 30K, when you need it the most! The last 10K in Odaiba were a bit deserted in comparison to the 5- or 6-deep crowds in Ginza. Oh, and the marathon expo was far better than New York's too, I found. There were many more choice, and it was probably twice as large. Overall, it didn't have quite the same magic as New York did, but it was a great experience nonetheless, and I will be back next year for sure.

I ran the 1st 2 editions of this race. The course is very fast, and the streets are wide, so there's great PB potential. Support is good in marathon-fanatical Japan.
