What is KarateDatu?
KarateDatu, formerly known as KarateZad, began as ‘Karate Z’. Zad Datu sensei first began teaching Karate on his own briefly in 2005 at a school, then together with his older brother, Nik Datu sensei, for two years from 2009 to 2010 at the university they both did their udergaduate studies. Zad sensei truly dedicated himself to teaching the art as a sole instructor from 2011 onwards up to six classes a week at multiple locations, including at UiTM where he appointed as coach for the university’s Karate team up to 2019.
2014 was when Zad sensei started using the name ‘Karate Z’ for a Facebook Group and Page as a platform for Zad sensei to streamline class management across multiple dōjo, covering everything from class schedules, grading results, syllabus distribution, attendance tracking, fee management, and more. ‘Karate Z’ also served as a central hub to keep students and other interested parties informed about news and activities related to his karate instruction.
Over time, Zad sensei adopted the name ‘Karate Z’, later evolving it into ‘KarateZad’ in 2016, as part of his personal brand for marketing purposes. During the pandemic, the number of classes reduced significantly. This was when, in February of 2020, that Zad sensei started his YouTube channel, establishing KarateZad as his brand.

After 11 continuous years of teaching Karate as the sole instructor of KarateZad, in 2022, Nik Datu sensei returned to the art and rejoined Zad sensei to establish KarateTTDI. Just before expansion of KarateTTDI, in June 2024, Zad sensei renamed the brand to KarateDatu—with “Datu”, a family title that has been used in the family continuously as far back as the 14th century, representing both brothers under one name and vision, then recruited more instructors to the team.
KarateDatu is a dōjo group representing M.A.S.K. (Malaysian Association of Shito-ryu Karate-do), and follows the M.A.S.K. syllabus, and hence the Shitō-ryū curriculum.
Values & Philosophy
KarateDatu Values
KarateDatu believes in and aspires to uphold and preserve the purity of Karate-dō and, most importantly, the honour of Karate-dō as a Budō, with sincerity and dedication.
This is in line with the M.A.S.K. (Malaysian Association of Shito-ryu Karate-do) Instructors' Code of Conduct, which reflects the vision of the first three Japanese sensei who pioneered Karate-dō in Malaysia.
Budō places character development, discipline, self-respect, and respect towards others — in a single word, ethics — as the highest priorities.
While KarateDatu, in part, also operates as a business and actively encourages students’ participation in championships and combat, in alignment with M.A.S.K. and Budō philosophy, KarateDatu prioritises:
- First and foremost: ethics, physical discipline, and the curriculum.
- Secondly: combat.
- Lastly: business or personal financial gain.
In our own words: in Budō, business or personal financial gain must never supersede combat, and combat must never supersede ethics, physical discipline, and the curriculum. Combat skills should not grow at the expense of ethics, but rather develop hand-in-hand through responsible and moral conduct of combat knowledge.
At KarateDatu:
- We believe that if an individual cannot be trained to handle combat skill and knowledge responsibly and morally, regardless from which martial art, then they are not eligible to attain these skills.
- We firmly oppose sacrificing the quality of teaching — whether in combat, functional techniques, the Karate-dō curriculum, physical education, or, above all, ethics — in exchange for financial or personal gain.
- We balance the kata-heavy curriculum of traditional Karate-dō with kumite (sparring), as we believe that the ability to defend oneself must not be neglected in martial arts, and that pressure-testing not just techniques but, more importantly, one’s reflexes and responses in combat scenarios is essential for self-defence ability.
Striving to uphold the principles of Budō is deeply embedded in the founding history of M.A.S.K..
The Spirit of Budō in M.A.S.K.'s History
Karate-dō was first introduced to Malaysia in 1966 in the form of Shitō-ryū by three consecutive Japanese sensei, each succeeding the previous, all based in Ōsaka.[1]
The third sensei, Mori Hidetoshi (森 英俊)[2], eventually faced a conflict of interest with the local organisation that had engaged him.[1][3] While the local party pursued business and financial gain, Mori sensei remained committed to upholding the purity of the Shitō-ryū Karate-dō style and preserving the honour of Karate-dō as a Budō.[1][3]
Out of necessity in upholding these principles, Mori sensei, together with two of his senior students whom shared his sentiments — Dr. Raveendran Raghavan and the late Shiekh Naser Bin Shiekh Anwar (both of whom had originally started their studies under the earlier two Japanese sensei) — established M.A.S.K. as a strictly non-commercialised non-profit organisation in 1969.[1]
M.A.S.K. is a strictly non-commercialised Karate-do organisation. The training provided by M.A.S.K. encompasses physical, mental and spiritual training subscribing to the concept and philosophy of ‘Budō’. M.A.S.K. adopts an open-minded attitude and approach in its efforts to promote M.A.S.K.. The difference in ryuha has never made M.A.S.K. fall short of accommodating and cooperating sincerely with all styles of M.A.S.K. in Malaysia. M.A.S.K.'s existence and direction have always been along the line of strict discipline. It is in this spirit and awareness that has kept M.A.S.K. united as a closely knit family. The members are always reminded and groomed to acquire a high degree of discipline and deep sense of respect for one another as well as others.
To ensure their vision was preserved for future generations, in 1977, Shihan Shiekh Naser drafted and formally implemented the M.A.S.K. Instructors’ Code of Conduct, which includes the following principles:[1]
- To uphold the purity of Karate-dō with utmost sincerity, honesty, dedication, and endurance in the spirit of Budō.
- To faithfully and diligently instruct Shitō-ryū Karate-dō and to always instil in students the spirit of Budō.
- To impress upon students, and the public at large through Karate-dō, the values of self-respect and respect for others, especially towards seniors and fellow instructors.
M.A.S.K. credentials:[1]
- Registered with the Registrar of Societies on December 1969
- Registered with the Commissioner of Sports Malaysia in 1988
- Founder member of thed Malaysian Karate Federation MAKAF founded in 1978
- Founder member of the Asia Pacific Shito-ryu Karate-do Federation (APSKF) founded in 1978
- Played host to trainees from Australia, India, Nepal, Indonesia, Middle East and Pakistan
The Birth of Budō and its Adoption into Karate-dō
The concept of Budō first made a conscious appearance through the development of Jūdō by its founder, Kanō Jigorō.
Kanō found himself as a Jūjutsu practitioner and master during Japan’s rapid Westernisation in the Meiji period[4][5][6] — a time when everything Western was regarded as superior over traditional practices, including Japan’s Ministry of Education adoption of Western physical education and repeated rejections of proposals to include traditional Japanese martial arts into the curriculum.[7][8]

At the time, the public perception of Jūjutsu was highly negative. In an 1898 lecture explaining the naming of his school, Kanō remarked that “jūjutsu had fallen into disrepute.” Although Jūjutsu contests did contribute to physical, moral, and intellectual development, these outcomes were incidental rather than intended. Moreover, the behaviour of many Jūjutsu practitioners where “senior pupils would want only throw down the juniors or pick quarrels, so that jūjutsu was despised as something that made rowdies of young men” in Kanō’s words.[9][10] This is somewhat reminiscent of the unsportsmanlike conduct observed among most modern “warriors” in the UFC. Kanō also criticised the staging of exhibition matches, some even Sumō wrestlers, and charging of admission fees, referring to it as the “degrading practice of prostituting a martial art.”[9]
To distance his teachings from this declining image, Kanō deliberately adopted the suffix ‘-dō (道)’, meaning “way” or “path”, instead of ‘-jutsu (術)’, meaning “art”, “technique” or “skill”, thus naming his art Jūdō. Although he was not the first historically to use the ‘-dō (道)’ suffix,[9][11][12] it was his influence that led to a cultural shift — from what had collectively been known as Bujutsu (武術; military skill) to Budō (武道; martial way), with ethics and etiquette placed at the heart of martial practice.[13][14]
... READ ALLIn 1911, the Japanese Ministry of Education officially incorporated Japanese martial arts into the school curriculum. By 1925, it formally mandated the use of the new terms Jūdō (柔道), Kendō (剣道), and Kyūdō (弓道), replacing the older Jūjutsu (柔術), Kenjutsu (剣術), and Kyūjutsu (弓術). Over time, these arts evolved into distinct disciplines, separate from it Bujutsu counterpart, the Edo period incarnation of military disciplines, from which they descended.[15][16]
When Karate was first introduced to Japan from Okinawa in the early 1920s, Okinawan masters initially added the ‘-jutsu (術)’ suffix to Karate to appeal to the Japanese audience. Originally, Karate was written as “唐手”, which translates to “Chinese hands”, pronounced “Tuudii” in Okinawan. In Japanese, it was read either as “Tōde”, “Tō-te” or “Karate.” With the ‘-jutsu (術)’ suffix, it became “唐手術”, romanised as “Tōde-jutsu”, “Tō-te-jutsu” or “Karate-jutsu”.[17][18][19][20][21][22][23][24]
Okinawa had endured over 260 years under Japanese domination — beginning with its invasion in 1609[25], transitioning into the Ryūkyū domain in 1872, and eventually becoming Okinawa Prefecture in 1879[26]. Unlike the dominating empires of Japan and China, Okinawa was a much smaller kingdom, and although it has its own fair share of internal warfare, it was nowhere near as massive, brutal or cruel. Okinawa had achieved unification and entered a peaceful era as early as 1429[27][28], some 170 years before Japan’s own unification in 1603 into the Edo period[29][30].
Consequently, the already smaller and less militarised Okinawan kingdom further weakened before and upon facing the invasion by Japan that though Okinawa defended, they were easily defeated. A positive cultural outcome of early unification was that the military systems of Okinawa has transitioned from warfare to recreational, character development and personal self-defence much earlier than Japan. The tradition continued even after Chinese martial arts, that too had already undergone personal development over warfare, were brought to Okinawa in 1750s and infused with indigenous Okinawa martial practices giving rise to Karate[31][32][33].
To ensure the survival — and ideally the flourishing — of Okinawan culture, Karate masters adapted aspects of Japanese culture into Karate when presenting it to mainland Japan. Apart from the adoption of the ‘-jutsu (術)’ suffix, Karate also adopted innovations by Kanō Jigorō such as the keikogi (training uniform), and the kyū (級) and Dan (段) belt ranking system.[34][35][36]
Despite the humiliation and pain that Okinawa endured from the invasion,[25] the Karate masters of Okinawan held great respect for Kanō Jigorō in regards to martial arts[37][38][39]. His Jūdō not only outcompeted the old Jūjutsu systems philosophically but also technically, consistently prevailing in contests and earning adoption as the official unarmed system for the Japanese police.[4][40][41]

In 1933, Karate was officially accepted as a modern “Japanese” martial art. Then, in mainland Japan from 1934 to 1935, there were emergence of the Karate was written as “空手道”, as how it is written today, in the titles of several of published books written by many notable Okinawan Karate masters in mainland Japan.[42][43][44][45][46][47][48][49] Here, “唐手” was replaced with a homophone also read as “Karate”, “空手” that appropriately meant “empty hand”, to foster better acceptance among the Japanese public, particularly given Japan’s tense relations with China at the time. Finally, in 1936, a meeting in Okinawa itself among the most influential Okinawan Karate masters, observing the growing popularity of “Karate” in mainland Japan, they too agreed to formally adopt the new written form, “空手”, in favour ofer the old over the “唐手”.[50] The ‘-dō (道)’ suffix was added, formally classifying Karate-dō as a Budō and signifying alignment of values — values that, by chance, similar to values that Okinawan martial arts had long embodied even before Japanese influence.
Understanding how deeply Budō values are embedded in the histories of M.A.S.K., Karate-dō, and Budō itself, KarateDatu aspires to actively practise and uphold these values today and for generations to come.
