Jion derived its name from Jion-ji which is a Buddhist temple in China. It is uncertain as to which temple this kata refers to as there are many Jion-ji temples that exist. Jion refers to the idea “Love and Goodness”. Sokon Matsumura has all the credit for the creation of this kata as he is believed to have learned this kata during the journeys he had to China, although the real creator of this kata is unknown. The pieces from Heian and Tekki kata comprise of this kata which is considered to be the simplest of the Sentei kata.
The most basic movements that Shotokan offers are contained in this kata which has 47 counts. This is a very simple kata and does not come with fancy moves. It is important that a student has very strong basics, or else the performance of join is sure to be weak. Thus this kata is regarded as the best kata that can be used to judge a person’s overall technique.
The basic idea behind this kata is that one has to be like Buddha while performing this, with a strong yet humble spirit. The person who performs this is judged based on the simplicity of the movements made but they have to be performed with much power and stability. Jion has been grouped along with Jiin and Jitte by the instructors as it is started with same hand-over-fist salutation and is very similar in movements.
