What kind of trainers are on your team?

Our team includes several trainers, including Issei Shima, our lead trainer and a former professional fighter who oversees our six Tokyo gyms (Roppongi, Shinjuku-Gyoemmae, Nishi-Shinjuku, Shibuya, Ginza, Azabu-Juban) as well as in-home lessons. Each trainer brings real competitive experience in martial arts or other sports. Please see the profile section on this page for each trainer's background and service area.

Can I request a specific trainer?

Yes. You may let us know your preferred trainer when booking. Each trainer's service area and assigned location are listed under the “Service Area” section on the instructor page.

What is the background of your lead trainer?

Issei Shima. He has competed in approximately 70 bouts across Muay Thai, kickboxing, and karate, with rankings that include Rajadamnern Stadium-certified S-Welterweight #9 in Thailand and WPMF Japan Welterweight #5. For his full profile as a business leader, please refer to alpha-edge.jp/about/issei-shima/.

Do you offer women-only time slots?

Yes. Women-only time slots are available at each location. Please ask when making your booking.

Can I train in English?

Yes. We offer instruction in Japanese and English. Language availability may vary by trainer, so please let us know your preference when booking. We also have extensive experience serving affluent clients and international guests.

Is it suitable for beginners?

Absolutely. Because every session is personal training, instruction is tailored to each client's fitness level and goals. Many of our clients are new to exercise and have no prior martial arts experience.
