About us

The Sekai Dojo club is a martial arts school of aikido for adults, youth, and children. We train in a friendly and supportive atmosphere suitable for all age categories and for beginners with no prior experience. Our goal is to offer a space for physical development that also supports personal growth and mutual respect.

The name of our aikido dojo, SEKAI DOJO, can be freely translated as "The world is my dojo". This idea reminds us that the values and knowledge gained in the dojo ("gym") should accompany our daily lives. In other words, we should apply aikido and its principles not only during training but also outside of it.

Classes take place regularly 2x a week for adults and youth (from 13 years old), 1x a week for youth from 13 to 18 years old, and 1x a week for children from 10 to 13 years old. In addition, it is also possible to attend a three-month aikido course for complete beginners. All practices are held at José Martího 269/31, Prague 6 – Veleslavín (see more in Contact).

How to Start with Aikido

Starting with aikido is simple. You can try your first training session for free and without obligation. You can just come to take a look, or jump right into training. You don't need any prior experience or special equipment – comfortable sportswear is enough to start.

There are 2 options for beginners:

① Join regular classes directly
Training runs from September to June, and the pace is fully adapted to complete beginners. You can join at any time during the year. Beginners are gradually introduced to the basics of aikido and integrate into the group at their own pace without any performance pressure.

② Take the three-month aikido course for complete beginners
We always open this course in autumn (September–December). The pace is more gentle and systematic, suitable for those who want to start in a closed group and gradually get familiar with the basics of aikido and the dojo atmosphere. After finishing the course, you can smoothly continue with regular training.

What it's like to train at Sekai Dojo

„At our dojo, everyone can learn aikido at their own pace. There is a great friendly atmosphere where more advanced members try to help beginners and pass on what they already know. There is no performance pressure, but at the same time, you can clearly see how far you can advance in the art if you try.“

„The training stretches my whole body and helps me keep it healthy. As a bonus, there is a really good group of friends here.“

„Great dojo with good practice and a nice mood. High-quality aikido under the guidance of good teachers.“

„I found myself on the tatami of Sekai Dojo for the first time when I was 17 years old. In the beginning, I couldn't do ANYTHING – and I didn't learn a proper fall (ukemi) until my second year (though I was an extreme case, most people manage it sooner). I kept coming back because of the team, because I always found support, understanding, and zero mockery at Sekai when I couldn't do something. Over the years, I built wonderful friendships with people from various fields, places, and age groups. And believe me, every aikidoka is unique and walks their own life path – and all these paths intersect on the dojo tatami. Or, as Sekai says: 'The world is my dojo.' Training has also instilled many qualities in me that accompany me every day – patience, discipline, inner peace, and endurance. And of course, getting up after every fall, literally and metaphorically (and there were – and will be – a lot of them 😊). I trained at Sekai for six years, during which I graduated from high school, found love, finished my bachelor's degree, and much more. And even though I have now moved abroad for my master's degree, I believe that when I find myself in Prague again, Sekai will welcome me back onto the tatami.“

Our club is a member of the Czech Aikido Association - CAA (Aikikai of the Czech Republic) with a direct link to the Aikikai Foundation - Hombu Dojo, Tokyo (the original aikido organization led by the descendant of the founder of aikido, currently Moriteru Ueshiba). The CAA is an aikido organization in the Czech Republic which is also an official member of the International Aikido Federation (IAF).

Within the CAA, it is therefore possible to take internationally valid examinations for Aikikai dan grades - Hombu Dojo.

The CAA also organizes numerous seminars during the year with Czech and international aikido teachers (see Seminars). In the past, these included teachers (Japanese: sensei, or shihan = a teacher who has reached at least 6th dan): Mitsuteru Ueshiba, Katsuaki Asai (8th dan), Masatomi Ikeda (7th dan), Yoji Fujimoto (7th dan), Hideki Hosokawa (7th dan), Bernard Caloz (7th dan), Gildo Mezzo (7th dan), Roger Schmocker (6th dan), Giorgio Veneri (6th dan), Daniel Vetter (6th dan), Michele Quaranta (6th dan).

The club was founded in October 2012.

Aikido Teachers at SEKAI DOJO

Otakar Horejs (5th DAN Aikikai)

I started practicing aikido in 1992 on the recommendation of doc. PhDr. Ivan Fojtík, CSc., who is one of the pioneers of aikido in the Czech Republic. I began practicing aikido in the children's aikido section in Žižkov (Aikido Kenkyukai Prague) under the guidance of a wonderful teacher, Jan Materna. Thus, I already have thirty years of experience with aikido and I am still trying to develop in this martial art. After a year of training in the children's section, I moved to the adult section of Aikido Kenkyukai Prague (AKP), where I trained until 2012 (mostly under the guidance of Miroslav Kodym).

At AKP, I later also taught once a week from 2005 to 2012. In October 2012, my friends and I founded a new club, AIKIDO SEKAI DOJO, where I now act as the head teacher. I hold the title of shidoin CAA, which among other things means that I can examine for kyu grades in our dojo, which precede the master dan grades. I have participated in countless seminars with European and Japanese aikido teachers.

In addition, I have visited the cradle of aikido – Japan – three times. In Japan, I studied aikido in several dojos, especially in the central Hombu dojo and Gessoji dojo (Shihan Hiroshi Tada, 9th DAN Aikikai). My aikido was initially influenced by the comprehensive teaching system of the Japanese shihan Masatomi Ikeda (7th dan Aikikai), who led the CAA organization since its foundation. However, in 2002, shihan Masatomi Ikeda had to end his activities due to health reasons.

After shihan Masatomi Ikeda ended his activities, I naturally searched for the most direct connection to the teachings of the founder of aikido, O-Sensei (Morihei Ueshiba). Therefore, in 2002, I went to Switzerland for the first time to an international seminar led by the Japanese shihan Tada Hiroshi (9th DAN Aikikai). Tada Hiroshi shihan (born in 1929!) is one of the last direct students of the founder of aikido, O-Sensei, and was also one of the teachers of sensei Masatomi Ikeda. At the seminar, I was captivated by the depth of his approach to aikido, which he also presents as "zen in motion" (a dynamic meditation leading to the unification of body and mind). Regardless of his age, Tada Hiroshi shihan is still incredibly vital (video from 2016 when he was 87 years old).

I have been traveling to his seminars every year since 2002 (besides Switzerland, he also organizes a 2-week seminar in Italy and weekend seminars in Milan, Rome, or Paris). In 2015, I passed the examinations for 4th DAN Aikikai. On January 8, 2023, I was awarded the 5th dan Aikikai in Tokyo. In the autumn of 2024, together with 4 members of the club, we undertook a journey to Japan for practice (Hombu dojo, Gessoji dojo) and at the same time, we enjoyed traveling around the islands of Hokkaido and Honshu, full of nature, culture, and new experiences. Since 2025, I have been a member of the technical committee of the Czech Aikido Association.
