In 2018, he came in second in the highly competitive lightweight division at the European Championship, the highest ranking for a Japanese athlete. His signature move, "DEEP HALF," has been recognized worldwide, and he released an instructional DVD in the United States in 2019. He has been teaching at CARPE DIEM BJJ for many years, producing many athletes.

■DEEP HALF CLUB's first instructional work
The YouTube channel "DEEP HALF CLUB" (hereinafter referred to as DHC) boasts an overwhelming number of views and subscribers in the world of jiu-jitsu. It is a major channel where all athletes can learn for free, regardless of level or style, with a variety of themes such as technique introductions, match commentary, and guest appearances by top athletes. There are many athletes who say, "I learned new techniques from DHC" or "I tried them out in practice with my friends."

The theme of this tutorial is "Half Guard", which is the specialty of DHC's founder Masahiro Iwasaki. It is also repeatedly featured on YouTube. I must explain the difference between packaged tutorial works and YouTube content.

One is the convenience of being able to systematically review half guard repeatedly. YouTube is not a series of videos, and the YouTube system is not designed for review. This book is suitable for watching repeatedly.

Another difference, and this is actually the biggest selling point, is that the content is also very different from the previous YouTube content. It is a thorough and in-depth look at the "principles".

■About the concept "principles"
The biggest feature of this work is that it does not just introduce the steps, but provides a thorough explanation of the principles of half guard.

This book is not about introducing multiple developments derived from the half guard, nor about increasing the number of sweeps. It starts with "The structure of the half guard", carefully explains the intricacies of offense and defense in the half guard, and ends with "The mindset for using the half guard".

The "principles" of this manual are, specifically, understanding the strengths and weaknesses of the half guard, keeping the half guard without any gaps, and keeping the opponent under your control. Regarding offense and defense in the half guard, Iwasaki clearly states that "the ideal is to push and have the opponent fall," and the contents of this manual focus on how to create that state.

The position of the shoulders, the direction of the hands, the length of the inserted arm, the height of both heads, the inclination of the waist, how to make the lapel, etc. Every movement is explained in detail, asking "why?" You will be amazed at the depth of detail.

This is the definitive instructional work for those who are just starting to use the half guard. If you understand this work, you will undoubtedly gain a deeper understanding of DHC's YouTube content and other half guard instructional works. Even if you have been using the half guard for many years, we recommend that you take the time to experience the difference in your own movements.

The half guard has many things in common between gi and no-gi, so this book will be extremely useful for grappling competitors.

The second book in the DHC SYSTEM series is "Deep Half" by Masahiro Iwasaki. We hope you will learn the principles of half guard along with this book.

■ Tomoyuki Hashimoto (IBJJF World No. 3, 4th consecutive All Japan Championship winner)
Just because you're focusing on open guard doesn't mean you can skip half guard. If you do that, the moment you enter half guard, it's game over. By improving your half guard strength, you'll be able to attack with confidence from open guard. Iwasaki's lessons, a half guard expert, are definitely worth buying.

■Masahiro Hayakawa (Representative of Gentle Arts Nagoya Brazilian Jiu-Jitsu Club)
In 2019, Iwasaki-san was invited to Nagoya for a seminar, and the content was about half guard. I was amazed at the details. It will surely evolve even more. I'm really looking forward to it ^ ^

■Takaya Okazaki (CEO of CARPE DIEM STUDIO)
Is it finally going to come out? Thanks to taking Iwasaki's strong and merciless half guard, I've developed a resistance and can pass other half guards besides Iwasaki. But it's scary to think that everyone will be able to use that half guard after this tutorial lol. I have a feeling this will be the definitive half guard tutorial.
