KuSakuraShop's Office, Staff & Commitments

KuSakura Original Mon logo

KuSakuraShop is a brand dedicated to the international export, managed by the company Seido Co., Ltd. Our offices as well as our entire staff are located in Tokyo. Our team consists of multilingual martial arts practitioners, who are in love with Japan.

Seido Co., Ltd. is a privileged partner of the company Hayakawa Textile Industries (aka KuSakura) since 2009, a traditional manufacturer we got to know in recent years. We analysed a large part of the market and worked with many stakeholders. It was because of this experience that we have chosen, and were chosen by, KuSakura to collaborate and contribute to the development of KuSakura worldwide.

Our Goals and Motivation

KuSakura, S logo

Our work is not limited to the export sales of KuSakura Judo equipment but also to advice and guide the brand in its communication, marketing and further also in the design of products for the international market. Thus, we have contributed to the modification of several products, the creation of additional Judogi sizes and the adjustment of certain product design elements, in direct connection with the feedback we have from our clients (and friends on the Tatami) outside Japan..

Our position as martial artists, and lovers of traditional Japan, is to offer only top quality material, with a service at the height of Japan's reputation in this field. That is why we chose to animate, to make KuSakura better known worldwide, and to supply all Judoka with the most authentic high quality equipment available today.

Jordy Delage - Seido’s founder

Seido’s founder: Jordy Delage
I'm amazed, how much my team evolved in just a few years. I enjoy the time I spend alone at the office in the morning, but it's when everyone arrives that my day really starts.

Hi, and thank you for taking the time to discover us.

My name’s Jordy Delage. I was born in France’s countryside in 1985. I’m married to Eriko, we’ve 3 kids, and we live in Tokyo’s suburb, close to our office.
I started Aikido at the age of 15, in France, in a group called “Academy Autonome d’Aikido”, affiliated with Kobayashi Hirokazu’s teaching. I moved to Japan at 19, before university, for intensive Aikido practice at the Aikikai Hombu Dojo and to discover more about myself. I then decided to stay in Japan, and it took me a few years to get a university degree in Japanese language and culture (majoring in Japanese religions). I practiced a little Kendo, Judo, and Taichi, but I always got back to Aikido, experiencing different schools, e.g., Yoshinkan, Iwama, and Kobayashi Hirokazu’s style and the Aikikai, to which I belong now.

After a few years of perfecting my Japanese and my Aikido, working in many fields, I decided to create Seido to fill something I considered as a void for many foreign Aikido practitioner. I’ve always been my first customer, and I focused hard on bringing to the international Aikido community the best brands I knew. After a while, not being very satisfied by the products or the support provided by other brands, and since I knew the artisans supplying the brands, I created my own brand, Seido. Doing so, I got the opportunity to give more importance to the artisans and really work on our customer’s needs.

This is where I've met KuSakura's senior staff, Mr Hayakawa Nobumasa and Mr Hayakawa Iwao. I've realized that KuSakura was the only company in the Budo industry with ethical standards similar to mine, and I've started a collobaration with KuSakura.
KuSakura is a Judo equipment specialist with the most incredible production capacity and quality, so it only needed our expertise to produce high quality Aikido equipment. KuSakura produces, on a OEM basis, many of our Aikido product sold under our brand Seido.
On the other end, KuSakura being a manufacturer, our international communication and logistic expertise was what was missing to the company. We established a win win partnership in which we fulfill KuSakura's needs for international logistic and communication, and they fulfill ours when it comes to production and quality.

I consider my encouter with KuSakura and its senior staff one of the best opportunities I've had since I've started working in Japan, and I feel infinitely grateful.

Eriko Hoshi - Japanese Sales & Suppliers Relations

Japan sales: Eriko Hoshi
Thanks to my father, a 7th Dan Kendo master, Budo has always been part of my life. I’m responsible for the Japanese clientele and Artisans relations...

Hello everybody !
Apart from being in charge of the management and administrative tasks, I'm taking care of the trader relationships. My father, a 7th Dan Kendo teacher, brought me to his practice when I was little; hence, I was always somewhat close to Budo. However, until I became an adult, I had no martial arts experience. I only started practicing Aikido after marrying my husband, joining him at the Dojo.
The customers are various; some have just started practicing, and others are high-grade black belts. I try to do my best in that new field, not only by crafting detailed explanations for our websites, but also by answering requests via email or on the phone, - especially because there is no face-to-face selling. That's why I have to be careful, so that our customers can order our products without worry.
It's a great honor to be an intermediary, introducing as many customers as possible to the Japanese artisans by offering high-quality martial arts equipment. So, from the bottom of my heart, I'm pleased to welcome you as our customer.

Jean François Rauch - General Manager

Jean-François Rauch - General Manager
I was seduced by his conviction that we had a duty to provide high quality equipment to our fellow practitioners, while preserving and encouraging the work of traditional Japanese craftsmen.

Hello everybody!
My full name is Jean-François Rauch, but most people simply call me Jeff. I was born in a small town in South Burgundy, France, in 1987. I discovered excerpts from the Hagakure by chance at the age of 15, thank to Jim Jarmusch's film Ghost Dog. I grew more and more interested in Bushido’s thoughts, which eventually led me to Kendo and philosophy studies. I started both when I moved to Lyon, at the age of 20. Japan was the obvious next step, and I first came to the country at the age of 23, meeting many great people and learning the language. I soon discovered Iaido, adding it to my Kendo practice. Since then, my life has been shared between my country of origin and my adopted country, spending every other year on each side.
The sword being the backbone of my life, it was a great opportunity for me to work for the industry of Budo equipment. I met Jordy Delage at an international Kendo event in Tokyo in 2017, and I was seduced by his conviction that we had a duty to provide high quality equipment to our fellow practitioners, while preserving and encouraging the work of traditional Japanese craftsmen. A few months later, I joined the team to help keeping this ideal up, and promoting the culture of Budo worldwide.

The ethical values associated with handmade products and the crucial relationship with traditional local craftsmen really appeal to me...

Hello everyone!
My Name is Gaëtan Karst. I was born in 1995 and I am from Réunion Island, although I also lived in Toulouse for 10 years.
Since I am a child, I have been traveling and lot, and have always been attracted by cultures that are different from mine. I am from a family fond of history and at the age of 12, I got really interested in Japanese history, culture, and traditions. Then It was natural for me to study this country and its language during my bachelor. In 2016 I had the opportunity to live for the first time in Japan as an exchange student at Hiroshima University. I chose that city for its tragic yet fascinating history. This experience made me learn a lot about both the country and myself and was a life changing experience. It also confirmed my project to live and work there once I would be done with my studies, and Seido gave me that chance.
At Seido, I am in charge of Kusakura’s International Marketing. I joined the team because I strongly believe in the company's philosophy, that is to sell quality products with high standard customer service. The ethical values associated with handmade products and the crucial relationship with traditional local craftsmen really appeal to me and I am looking forward to learning a lot here!
Thank you very much and see you on our shops!

I'm looking forward to really learn many things here in Japan and at KuSakuraShop.

My name is Antoine Brisseau. I was born in France in 1989 and living there until late 2017 when I moved in Tokyo. I tried Aikido during my studies in Nantes and practiced it for 4 years. I went on holiday in Japan and really enjoyed my trip, I liked the many historic spots and I loved the japanese food! I finished my trip with an interview here as I felt working with the KuSakuraShop team would be a really great opportunity. A company with a good spirit combining many interests of mine like Information Technology, Aikido but also Craftsmanship and especially Wood Craftsmanship.
I'm in charge of all IT matters and trying to facilitate processes in order to serve our customers in the best possible way. I'm looking forward to really learn many things here in Japan and at KuSakuraShop.

I will do my best to make your experience of SeidoShop as pleasant as possible.

Hello everyone and thank you for visiting SeidoShop!
I am Tony Duong and I am French of Vietnamese origin. Since I was a child, I have always been fascinated by Japan through its pop culture (animes, music and such). I finally went to Japan for the first time in 2016 as an exchange student at Tsukuba University. From that experience, I got to know more about Japanese lifestyle, Japanese language and the unspoken rules of the society.
My affection for Japan has grown even further to the point that I wanted to settle here for some time. And here I am, now working for SeidoShop in the IT department, creating new tools that help improving the quality of the work done by the team. Having no prior experience in the world of martial arts, to be in touch everyday with martial arts practitioners has made me learn more about its morals and values. I will do my best to make your experience of SeidoShop as pleasant as possible. Thank you again.

Alexandre Venancio - Order Preparation, Shipping & Warehouse Management

Alexandre Venancio - Order preparation
Passionate about Japan and diverse aspects of the Japanese culture, I’m the one who gets your order ready for shipping...

My name is Alexander Venânçio. I’m of Portuguese origin, born in 1988 in Paris.
Having had a grandfather in the Navy, who traveled around Asia, I got in touch with Asian cultures at a young age and was mainly attracted to the Japanese culture, which is so different from ours.
This encouraged me to practice Judo for several years. Why Judo? you may ask. I've first started Judo because it is a very popular kid activity in France. Growing up, Judo values like Respect, Modesty, Self Control and Politeness really talked to me. For me, Respect is a great value. As a kid, I learned how to practice and fight with respect for my opponent. Practicing Judo was a very rewarding experience.
My passion for Japanese arts, be it drawing, music, or architecture, but also its history, made me engage in this culture, loving this country more and more. After many travels to different regions of Japan, I finally moved to Tokyo to live daily in the midst of this culture.
I got the chance to meet and work with a very dedicated team, retrieving the mentioned respect among the practitioners, and vis-à-vis the Japanese culture and its traditions.

Aya Yamamoto - Embroidery Workshop & Manager

Aya Yamamoto - Embroidery workshop Manager
Using the latest embroidery and sewing machines, I put my heart into offering you high standard Dogi customizations...

Hello everybody!
I mostly execute the Dogi alterations (like cutting sleeves/trousers, sewing reinforcements on Hakama etc.) and accomplish embroideries. Experiencing the bubbly energy of my two little boys daily, I was looking for an activity for them. The spirit of Aikido, in which winning or losing isn't a matter of physical strength and proper etiquette is taught during practice, seemed to be a good option. I'll never forget my boys’ facial expressions, bursting with pride, when they put on their first Dogi: Jacket and pants, embroidered with their names, made just for them!
We have the latest embroidery and engraving machines so we can customize the equipment and have them delivered with almost no delay. It's very rare that we can actually meet our customers in person; nonetheless, we are putting our heart into making a unique Dogi, trying to satisfy everyone who opts for our high-quality products. If you stay somewhere close to our shop, don't hesitate to drop by, because we'd love to meet you.

Hi everyone!
My name is Nicolas Nothum, I was born in the north-east of France in 1984.
I always had a strong interest in Japanese culture and I first visited Japan in 2010. Since then, I had the chance to come back many times and finally decided to settle in Tokyo in 2014.
I got in touch with Seido in early 2015 as a freelance photographer for their KuSakuraShop project and had the opportunity to work with them on diverse occasions. Now, I'm in charge of their digital media, I take care of everything related to video, photo and (almost) the entire visual content you see on our websites and YouTube page. I'm excited to be a member of this team and work on projects that will provide useful information about the Budo universe. I hope to offer content that catches your interest and piques your curiosity, content, that makes you want to see more. But above all, I want to highlight the amazing work the last Japanese traditional artisans do to create your equipment.
Be sure to stay updated and check our sites and social media regularly!

Satomi Kanazawa - Embroidery & Alteration
I always keep in mind the contented smiles of those who occasionally dropped by the shop...

Welcome to SeidoShop.
I was taught machine-sewing by my mother from a very young age, before I start studying both Western dressmaking and Japanese traditional clothing manufacturing at a specialized school.
In 2015, my son started Karate; it was the occasion for me to get interested in Budo and to discover Seido. Since I joined the Seido Team, I cultivated my sewing techniques and of course also developed it further; being constantly in contact with the careful craftsmanship and the attention to details dear to Japan, I learn a lot myself.
From the workshop, I do not exchange much with customers, but I always keep in mind the contented smiles of those who occasionally dropped by the shop to get their Dogi while I’m working on customizing new items.

And our former employees and interns : Lukas Kucharsky, Maho Somekawa, Jacques Gonzales, Rémi Bouchez, Florian Fasel, Stéphane Durand, Ines Ouedraogo, Charaf Abdelmeziane, Jason Faivre, Narjes Achour, Adrien Guigon and Tony Duong. They all contributed to what we are today, and all of them will always be part of our story.
