Osu! In Kyokushin, every question is answered with Osu. Every greeting is Osu. Each instruction or question in the Dojo is the answer to "Osu" instead of "yes" or "I understand." Speaking kihon waza (basic techniques) in the dojo, each technique is often accompanied with a loud "Osu". You say "Osu" to recognize your opponent's skill. As a sign of respect, the fighters in the tournament bow and say "Osu" to the front, the referee and each other, before the fight and after. This is Osu. Osu is a combination of the words: Oshi, which means “Push”, and Shinobu whihch, “endurance.” It means patience, determination, evaluation, respect and perseverance. This is Osu. Kyokushin training is very demanding. You grow until you think you have reached your limit. At first, your body wants to stop, but your mind keeps moving. Then your mind wants to stop, but your spirit keeps you going. You endure the pain. You persevere. This is Osu. Quickly Karate Kyokushin cannot be comprehended. It takes years to properly learn the basic principles. The basic methods are thousands of repetitions performed until they are made a reflection or instinct, without conscious thought (mushin - "no mind"). It is easy to get frustrated by doing the same thing over and over again, especially when progress seems to be slow. Patience and determination will help to overcome frustration and continue learning. This is Osu.
