57th All Japan Open will be held 18-19 October 2025, with good support from outside Japan. (picture from 52nd edition)
With nations like Kazakhstan and Poland (and more) in the tournament, it is safe to say that more space are being added to the The All Japan Open.
It is highly interesting to see that it seems strong as it use to be – no rest for the fighters. But again, we do have some longer distance between the All japan Open and the World Championship held earlier this year.
Compared with the European Championship, where it is (special in the heavier categories for men) a little-bit lack of top names in the same way that we are used to see. But it is expected, anticlimax after The World Championship is nothing new.
In the women’s division we have 37 fighters, with the absolute top fighters attending. With Mihiro Suzuki, ⇓ Ramu Amikawa, Momo Fujihara and Yuna Mokudai as top seeded fighters, one can understand the level. 
Outside entries
A handful of non Japanese fighters are also in the line up, Kazakhstan ( ⇓ Valeriya Kristina) and AIN (Russia) (AIN stands for Athlète Individuel Neutre, the French name for individual neutral athlete with AIN both the acronym and IOC country code. Or Authorised Neutral Athlete (ANA)
No doubt that the level of the fighters for outside entries possesses a very high level, but It would be a surprise if someone could manage to reach the top, taking out the home fighters from japan.
Men’s division
In the men’s division we can find 82 fighters in the line up. And just by watching the number of fighters, we got the idea how hart it will be to win.
A important factor to notice when it comes to fight in the All Japan Open. If we compare this tournament to any other in the world, it is a certain difference when it comes to the experience. A very good EC Open-weight, will have 40 fighters in the men’s division – but usually 30 + (or down to 20 as it was in 2024)
The number of fights will for sure play an, and also when the championship goes trough two days, instead of one. 3-4 fight or 6-7, that’s can be the difference, a that’s some difference fore sure.
In short: The All japan Open are very much alike a World Championship in the settings, and the fighters who are used to fight in this format will also bring it when the World Championship goes of. ( 54th All Japan winners)
Several nations from outside Japan fills the tournament, with Kazakhstan, Poland and AIN (Russia) in the lead, being the strongest nations. AIN are represented with their top team, the same from Kazakhstan. (Anton Zimarev ⇓)
Poland seems to be in at shift of generations, and gives the next generation the absolute best experience with participate in All Japan. Poland have good traditions with this, and many strong fighters has been shaped here.
Samuel Hallas / Denmark will also attract interest. Working his way upwards in the European region, but doing so be living, training and fighting in Japan.
Japan has a strong turnout as always, with WKO’s top names at the forefront, spiced up with top fighters from other Japanese organizations as well. Byakuren Kaikan, Takahashi Dojo (Yuta Takahashi) etc
