First, TATORU KIDZ is a physical activity. As noted on the home page, if you want your child to do well in studies, they should do physical exercise alongside cram school.
Physical activities include gymnastics, swimming, soccer, ballet, and so on. So what is the decisive difference between those and TATORU KIDZ?
TATORU KIDZ teaches a martial art. What only martial arts offer is learning etiquette. Children learn to greet people.
Among martial arts there are karate, judo, kendo, and more. Why TATORU KIDZ among them?
First, jiu-jitsu has few injuries. Martial arts with striking are practiced assuming injuries. And in judo, with its throws, a few children every year are thrown and seriously hurt. Brazilian jiu-jitsu, with no striking, is reassuring in that respect.
At the same time, it is first-rate self-defense. At TATORU KIDZ, children learn self-defense they can use for life.
The monthly fee is 8,000 yen, but there are about 22 classes a month, so it comes to about 363 yen per class. Over a year that is 96,000 yen. A gi costs about 10,000 yen a year, so for about 110,000 yen a year you can upgrade your child's character.
Over 5 years, that is 550,000 yen. For a total investment of 550,000 yen, your child gains an overwhelming difference in both physical and mental ability compared with children who don't do it.
