Karate-do is a Japanese martial art, originating in the Ryukyu Islands (present-day Okinawa prefecture, Japan).
It is one of the many styles of KARATE-DO that exist. It was founded by Kenwa Mabuni Sensei, a prestigious Okinawan expert, widely regarded as one of the most influential figures in modern karate. You can find a lot of information about him on the web.
SHITO RYU is the union (Not a mix) of two of the main styles practiced in Okinawa (Shuri-te and Naha-te).
Like judo, karate uses the Japanese system of kyu/dan. They are 9 degrees prior to obtaining shodan (black belt). The color of the belts usually varies from organization to organization. In the case of our school we have the following: White, Yellow, Orange, Green, Blue, Purple, Brown, and Black
The exams are every three or four months, but ranks above brown belt, the students are examined every six months.
The SHODAN (black belt) exams only occur once or twice every 2 years. Depending on the number of students that will be taking the exam.
However, the students who meet the requirements and the necessary preparation at the time, can be examined at the HOMBU DOJO of our school (Monterrey, Mexico) or directly in Japan, on the dates scheduled at said locations.
