Kensuke Gunji’s 1-Step Uchimata System: Front Step vs Back Step Explained
In this detailed breakdown, Kensuke Gunji — two-time All-Japan qualifier and runner-up in Japan’s professional judo league — teaches the art of the 1-step uchimata. With precision and control, Gunji lays out three clean variations of one of judo’s most iconic throws: the front step, the back step, and the reaction-based uchimata.
This session is more than just mechanics — it’s a masterclass in timing, grip strategy, and fluid transitions.
“When the opponent tries to break the grip, I follow their movement. That’s when I go,” explains Gunji. “If my right foot is back, I go front step. If it’s forward, I change and go back step.”

Front Step vs Back Step Entries
Gunji starts with the front step variation — a traditional uchimata where the lead leg is placed forward before sweeping through with the back leg. It’s powerful and familiar to most judoka.
Then, he demonstrates the back step version — using a single committed movement off the rear leg, especially effective when the feet are staggered or his right foot is already forward.
The key? Reacting in real time.
Read and React: The Third Uchimada
What separates Gunji’s system is the third variation — a reaction-based throw. When his opponent tries to escape to the side, he shelves their leg and circles around for an explosive finish. This option ensures that even if the first two variations don’t land cleanly, you’re never out of position.
“When they try to sidestep, I go high posture, shelf the leg, and rotate. That’s the finish,” he says.
This layered approach gives you a backup plan, making your uchimata not just a throw, but a system.
