Company Profile / Gorudo Sentai Co., Ltd.

The power of sport,
turned into learning and work for the next generation.

More Than a Sports School

You learn
more than just sport.

Running faster. Doing something for the first time. Cheering on a teammate. Each moment builds a child's confidence. ASA is not a school that only teaches winning. Through running, thinking, and working with friends, we raise children who can take on challenges by themselves.

Children sprinting at full speed

01 — Run / Jump / Throw

First, run right.

Run, jump, throw. Master the fundamental movements behind every sport, matched to each child's age and growth.

02 — See / Think / Move

See it. Decide it.

Read the situation, choose, and move. Eight sports build decision-making, teamwork, and sports IQ.

03 — Try / Respect / Grow

Fail. Try again.

Greetings, discipline, challenge, respect for teammates. On the field, children learn to stack small wins and losses into strength.

Multi-Sports. More Possibilities.

Multi-sports to find
what you love — and excel at.

Before specializing, children explore a wide range of movement and discover the sport that fits them. A seasonal rotation builds a broad, deep athletic foundation.

  • 01Discover what you love and what you're great at
  • 02Build a movement foundation for every sport
  • 03Grow the flexibility to face new challenges

Founder & Head Coach

~ Next stop: the Olympics, via ASA ~

In Thailand, I have seen so many children with real potential whose skills plateau. I founded this academy to change that, drawing on my own experience.

Through sport, we will keep expanding children's possibilities. I first took on Thailand in 2012, and this country helped me grow both as a professional player and as a person — now I give back, through sport.

Our Philosophy

Our Philosophy

Sport should never end at competition.
It is education that connects people, countries, and the future.

Vision

Expanding possibilities through sport

Through sport, we grow Thailand's sports culture, expand children's possibilities, and enrich their futures. We act as a bridge connecting Thailand, Japan, and countries around the world.

Mission

Faster, stronger, and more fun

We provide an environment where children unlock their talent through track & field and multi-sports.

Values

No effort beats being hooked

By helping children find a sport they can be truly absorbed in, we raise independent, self-driven kids.

Purpose

Turning athlete experience into value

Through multi-sports, we contribute not only to children but also to careers for many athletes. The experience athletes carry is unquestionably valuable. ASA provides an environment where athletes can teach the sports they love.

Fitness Test

Know Your Own Strength Through Fitness Tests

Your rival isn't someone else — it's you, three months ago. At ASA, we run a fitness test every three months so each child can see their growth and strengths clearly, as numbers. Once it's a number, you can check for yourself both how far you've come and what to work on next. We then set a goal for the next test and keep training to reach it.
