Best BJJ Gyms in Tokyo: What Reddit Actually Says

Tokyo’s BJJ scene runs on three big names, one MMA legend’s dojo, and a set of etiquette rules that surprise most visitors. This guide collects what Redditors actually report from training there, 2018 to 2025, with the practical details that matter in Japan: contact ahead, expect drilling-only open mats, and don’t worry about your Japanese.

Verdict at a Glance

One rule covers every row: “I don’t know of any that accept walk-ins” (r/bjj, 2023). Email or message a day ahead, every time.

Axis Jiu-Jitsu Academy

The gym with the deepest stack of positive visitor reports in our data, run by Takamasa Watanabe under Rickson Gracie:

“I dropped into a Rickson school in Tokyo. It was awesome… Axis Jiu Jitsu run by a Japanese Brazilian by the name of Takamasa Watanabe. He’s like a 3rd or 4th degree black belt under Rickson. They were super welcoming and very legit.” - r/bjj, 2022

“The instructor teachs in English and Japanese simultaneously.” - r/bjj, 2025

It is also the standout report for women visiting Japan: “Axis BJJ has been my go-to. They’re super nice, and there were a mix of locals and non-locals there. There were at least 3-4 women out of the 3 times I’ve gone… You can also wear whatever gi color you want.” (r/BJJWomen, 2025)

Carpe Diem

The default answer when tourists ask where to train:

“I train at Triforce but if you’re coming as a tourist I recommend the Carpe Diem dojos, they have the nicest facilities and are probably the most equipped to handle foreigners. You do need to contact them in advance.” - r/bjj, 2023

“I dropped in at Carpe Diem Aoyama and have only great things to say about it. Super chill team that rolls hard.” - r/bjj, 2025

Tri-Force

The homegrown powerhouse, with Ikebukuro as HQ and branches across the city. Visitors report smooth drop-ins even without Japanese:

“I went to… Tri Force in Shinjuku, Tokyo… Tri Force was taught by a Japanese black belt in Japanese but you could figure out what was going on.” - r/bjj, 2023

A 2024 local thread even rated the Shinjuku branch above the HQ for visitors passing through that side of the city. Shinjuku: profile · Ikebukuro (HQ): profile · Gotanda: profile · Ojima: profile

Imanari Jiu Jitsu

Masakazu Imanari’s gym in Shinjuku, and the best story in the dataset:

“I dropped in to Imanari jiu-jitsu a few weeks ago while in Tokyo. He heel hooked me about 6-7 times during our roll, laughing the whole time. The gym has a great vibe and is very clean. Highly recommend.” - r/bjj, 2025

An earlier visitor agrees: “Imanari Jiu Jitsu was awesome. Real great vibes, guys all over dropping in and just a generally great spot.” (r/bjj, 2024) Drop-in confirmed in our directory. Full profile

Know Before You Go

• No walk-ins. Contact every gym at least a day ahead. “It’s just proper etiquette and expected.” (r/bjj, 2023)
• Open mats are for drilling. “One thing of note, open mats in Japan are purely for drilling, not rolling like in the US.” (r/bjj, 2024)
• Language is not a blocker. Every quoted visitor trained without fluent Japanese; Axis teaches bilingually.
• Gear: visitors recommend the Isami store and Grit Fight Shop in Shinjuku for gis and gear.
