R.I.P. Master Charles Merhib

It is with great sadness that I report to you the passing of Master Charles Merhib today at 12:40 PM. (11/26/2019)

Charlie was 93 years old and had practiced Uechi Ryu Karate Do as a member of the Walter Mattson Dojo Group for more than 50 years. He was a great friend of late Master Ryuko Tomoyose as well as Master Shintoku Takara.

He was promoted to 9 Dan in 2012 together with late Master Peter McRae and Master Clark Jones.

President Darin Yee of IUKF 2019 Visit to Honolulu Uechi-ryu Karate-do Club

November 14, 2019

Darin Yee works with kid’s class

In the Hawaiian Language, the word “ALOHA” mostly functions as a salutation and a greeting. But the word actually conveys a deeper sense of meaning, which the locals expound upon, by breaking the individual letters down into other Hawaiian terms:

A – Akahai: Kindness, expressed with tenderness

L – Lokahi: Unity, expressed with harmony

Darin Yee with Al

O – Olu’olu: Agreeable, expressed with pleasantness

H – Ha’aha’a: Humility, expressed with modesty

A – Ahonui: Patience, expressed with perseverance

Aloha is more than just a word of greeting or farewell or a salutation. Aloha means mutual regard and affection and extends warmth in caring with no obligation in return. Aloha is the essence of relationships in which each person is important to every other person for collective existence. Aloha means to hear what is not said, to see what cannot be seen, and to know the unknowable….

On November 9, 2019, Darin Yee-Sensei travelled 5,046 miles from Boston to Hawaii to share his extensive knowledge of Uechi-ryu, to offer his continued support of our Dojo, and to spend his valuable time with us. From the multiple meetings and training sessions throughout the week, we gained much insight into the Tiger, Dragon, Crane roots of our art. We are so grateful to have been shown a new perspective from which to dissect, analyze, and maximize our effectiveness in Kata performance and applications. I’m particularly impressed with the humble manner in which Darin-Sensei interacted with our group. From the youngest member, to the oldest member, he showed patience, kindness, and understanding in freely sharing his knowledge.

Sensei Yee, thank you for your on-going efforts in building a highly supportive International Uechi-ryu Karate Federation, and especially for travelling so far across the globe to help us become better Karateka! Mahalo nui loa for embodying the Spirit of Aloha! We are proud to be an IUKF affiliated Dojo and look forward to your next visit on January 11th and 12th 2020 for our Honolulu Uechi-ryu Gasshuku Regional Workout.

IUKF President visits Knoxville

Recently 9th degree and newly appointed president of the IUKF, Darin Yee, paid a visit to our school in Knoxville, TN. It is a privilege to be able to learn from Master Yee’s vast knowledge from not only Uechi-ryu but also his many other martial arts styles.

These influences are easily seen, especially Wushu and Wing Chun, when exploring the soft side of Uechi-ryu. Even though most original styles of karate advocate being both a hard and soft style, through the years of evolution of karate, many styles have the lost the soft side. Master Yee’s seminar focused on the soft side of Uechi-ryu.

The soft side is an overlooked and important facet of Uechi-ryu. This is especially true in today’s modern karate where women and children are an intricate part of the dojo. The soft side gives a smaller or weaker individual the ability to defend themselves against a bigger, stronger attacker. No matter how big and strong you think you are there’s always a chance your attacker is bigger or stronger.

At our school we are always looking for a deeper understanding of movements, looking for bunkai not typically associated with the movement or set of movements in a kata; throws, takedowns, or a strike that could be a block and vise versa. Master Yee’s insight into the soft side of Uechi-ryu has given us new techniques to add to our repertoire, but more importantly help open our minds to even further explore the depths of Uechi-ryu.

Thank you Master Yee for taking the time to share your knowledge with our students at the Knoxville Uechi-Ryu School. Please feel welcome to come back and share your knowledge and friendship whenever you are able.


Thank you,


Knoxville Uechi-ryu

2019 Winterest review

Very nice letter from a long time student and friend, Harvey Liebergott to George Mattson. He has attended 99% of the camps since we started.

I have never been on facebook.  What I wanted to say about the camp is that it was beyond my expectation.  I learn something every time you and (during the last few camps) John Spencer take me through a kata.  But quite aside from that, I watched (because the four inch gash in my leg from an injury before the camp kept me out of) one of the best classes I have seen in more than forty years of training and camps.  Roy Bedard taught an unforgetable, lucid, class in how to read an opponent and lead him out of position.  I had never taken a class with Roy because I thought that I was too old for what he was teaching.  But in fact, I needed exactly what he teaches and even though I could not participate, I agree wholeheartedly with the great Yogi Berra, “you can observe a lot by watching.”  It would have been worth driving fifteen hundred miles for that class alone.

That is not to say that the other classes were not great.  In fact, winter camp felt like the early Uechi camps of the 1980s.  And what I found particularly inspiring was seeing the senior seniors learning from each other.  The greatest athletes and musicians and actors have coaches.  And it occurred to me that the best martial artists are not the ones who think they know everything, but the ones who keep working.  I have not been to Okinawa, but I am guessing that I would not see the “great names” there working together the way they do here.

Happy New Year!

Last workout in 2018 was a great class with Tim and Patty Dado and Joe Bellone , special guest from New England. 

Joe is an amazing Uechi-ryu practitioner who has a boxing and mixed martial background that gives him an insight into the many layers often overlooked in traditional martial arts.

We are looking forward to seeing Joe back at Winterfest where we can continue exploring the fascinating art of Uechi-ryu.

Happy Thanksgiving

The IUKF is extending a sincere wish to our Uechi family for an abundant Thanksgiving. Every year that passes presents different obstacles and so many new gifts. I pray our blessings outweigh any and all our burdens.

Please remember the IUKF is your martial art family. We are at the pinocle of the martial art world and yet we continue to grow and expand.

Rest and enjoy those love ones among you. The IUKF wish you a bountiful and fulfilling day. These types of days should remain with us forever.

Darin Yee – New IUKF President

I want to thank Sensei George Mattson for his trust in me to carry on the IUKF as president. Along with this position comes a huge responsibility involving fairness, compassion and understanding while keeping in mind our enormous affiliations throughout the world.  We must also maintain our insistence to all rules and guidelines with no exceptions. 

Every effort will be utilized to grow and to advance the IUKF.  As expected small changes will be announced.  Please follow our posting on our website. 

I appreciate all the well wishes I’ve received and look forwards to working with all our dedicated members. 

I would also like to announce the IUKF is an official 501-C3 organization which means we are a non-profit organization and all funds forwarded to the IUKF could be tax deductible.   

As President, I have been a businessman owning and operating businesses for over 30 years.  Our Secretary Mario Rizzo is an attorney at Law who will address all our legal issues.  Andrew Fink is a CPA with an abundance of experience dealing with the IRS and well versed with “non-profits”.

The IUKF thanks you for your support through the past years.  We hope to maintain our relationship as the torch is passed and continue to help grow and improve the legacy of Sensei George Mattson our Grandmaster.        

Darin Yee
