緊急事態宣言解除後について / Regarding circumstances once the State of Emergency has been lifted


Hi, I am Thomas Mietz, the head instructor of Carpe Diem Jiyugaoka. After spending the last 5 years training and competing professionally, I am now dedicating my time to teaching and running the Jiyugaoka dojo.

Jiyugaoka has been designed with the idea of a place 100% dedicated to BJJ. Its wide mat space, convenient location, top instructors and variety of classes are making it one of the best dojos to train at in Asia.

All of our instructors are highly decorated competitors and specialists in BJJ. But more than being competitors, they are also highly-skilled and professional full-time instructors.

Our priority is to help you achieve your goals whilst making sure that you are having a great time and staying safe.

We have classes which cater to all abilities and ages; adults, children, beginner, advanced, competitors and practitioners. Whatever your physical condition, age, gender or nationality, we can help you to learn Jiu-Jitsu.

Brazilian Jiu-Jitsu, a booming sport worldwide

From a fitness perspective, BJJ is particularly interesting because it requires a good combination of agility, flexibility, stamina and strength to perform. From the level of Blue Belt, we can say that any BJJ fighter is a true athlete. But that's not all…

Mentally, it takes a good understanding of body mechanics, body dynamics, movement, coordination and spatial-awareness. It can sometimes be like gymnastics for the mind because it forces us to be focused and organized in the processing of information in order to acquire experience.

Emotionally, BJJ is a great way to develop self-control. Having to deal with physical pressure can be compared to our struggles in everyday life, where most of our issues can be dealt with when approached with a calm analysis and choosing the appropriate response. Keeping cool in any situation, especially in the worst situations, is a must.

BJJ teaches us strong values like respect, determination, commitment and humility. But it is also a fun sport, where creativity is encouraged and where one is constantly pushed to learn and develop new techniques and combinations. BJJ is a martial art because it is a style of fighting that requires someone to control a resisting opponent without hurting them, whilst using the minimum amount of strength and the maximum amount of technique. But we quickly realize that often our first and toughest opponent is ourselves! Finally, it is also an activity that pushes us to a greater level of introspection and spirituality. We practice in a sacred-like place; the dojo, wear a uniform; the gi, go through a difficult ranking system to reach the symbol of accomplishment; the black belt.

Our Vision

At Jiyugaoka, we will continue the ethos of Carpe Diem BJJ being "basically a place to sweat and learn techniques" in the words of Mr Ishikawa (director of Carpe Diem BJJ).

The space, changing rooms and mat area have been carefully designed to fit perfectly and attain the highest standard in the practice of combat-sports.

Our aim is to create a warm, welcoming and relaxed place to learn BJJ whilst spending time with friends and family.

The structures and materials were carefully chosen to create that unique CARPE DIEM BJJ touch.

What is CARPE DIEM for you?

To me Carpe Diem BJJ is a place where we can train hard and forget about our concerns and everyday life problems. Being a member here helped me to get integrated into Japanese society, being a foreigner doesn’t really matters on the mat.
I am proud to represent Carpe Diem, and also happy we have dojos in various countries like England, Singapore and South Korea. The international aspect of our dojo is very important to me.
I entered Carpe Diem BJJ when we had only 2 gyms. Now we are more than 15! I think we really have what it takes to be part of the elite of BJJ and also bring our special touch in it! I entered here when I was a fresh Blue Belt and went all the way to Black Belt. All I can say is the level of training we have is world class.

  • JBJJF All Japan Championship 1st place (Black belt,Middle,2019)
  • UAEJJF Abu Dhabi Grandslam Tokyo 1st place (Brown belt,-77kg,2017)
What is CARPE DIEM for you?

Carpe Diem BJJ is a turning point for me. I’d been training in jujitsu as a hobby, and eventually I came to Tokyo to fully develop my interests and become a stronger man. I feel I am absolutely achieving that through the high-quality training here and experience in overseas tournaments among other benefits. Every day I spend at Carpe Diem BJJ is fantastically encouraging at the highest level, just as I'd imagined it could be. I intend to keep training here and grow even stronger.

  • UAEJJF Abu Dhabi Grandslam Tokyo 1st place(Purple belt,-69kg,2019)
  • JBJJF All Japan Championship 1st place(Purple belt,Feather,2019)
What is CARPE DIEM for you?

For me, Carpe Diem BJJ is where I can gain a lot a valuable experience. If you work at a typical office, you could lead an ordinary life. That might be a good thing for some people...but I want my work to be jujutsu, the kind of work where I can forget everything else, even myself, and get completely lost in it.

A place where I can be free to train my best jujutsu to my fullest extent. That is Carpe Diem BJJ.

What is CARPE DIEM for you?

To me, Carpe Diem is a place of opportunity. It is a hub of talent and dedication towards the improvement and evolution of jiu jitsu. With so many like-minded people, the rapid rate of progression is inevitable. Each day we push each other to be better than we were yesterday, even by just 1%.

Being at Carpe Diem has allowed me to live through jiu jitsu, sharing and gaining knowledge on what I am most passionate about. I think that a place offering this kind of opportunity for its staff as well as for the members to learn from such a wide variety of instructors is very rare and for that I am always grateful. I could not ask for a better place to train and teach!

They will learn

Self Defence / Anti-Bullying

BJJ is one of the most efficient combat-style systems. The kids will learn how to deal with physical aggression, control their partner and subdue them without hurting them.


BJJ is also a martial art, and we cary rules and values that are meant to be respected inside and outside the dojo.


Through games and activities, kids will expend energy and laugh! It’s important to us to maintain the children’s interest and keep them engaged as they will learn better if they have fun on the way.


Children will also learn how to control their bodies and how to move well. They will become stronger, more flexible and more balanced.


Learning how to deal with an aggressive opponent but also their own fears and worries will help your children to become more confident and resilient.
