That would be Choki style Karate, developed by a contemporary of Gichin Funakoshi, Motobu Choki. Many Japanese familiar with the Choki style, in fact consider it more practical than Shotokan, since its movements are not as expansive, and the Kata emphasize simplicity and efficiency rather than "showy" and "big" motions. It may be of interest to you, that Choki was a street brawler, and he had the same mentality as Bruce Lee; Motobu Choki felt that most Okinawan Karate "did not work on the street" so he developed his own out of his own street brawling experiences. Long before Masatatsu Oyama and his Kyokshin, there was Motobu Choki.
There are not that many moves in any style, they are all pretty basic in their moves. to attempt to quantify it is not likely to be successful.
There is no smallest number and no biggest number. Given any big number, however big, it is always possible to find one that is bigger (and the same with the smallest).
7 and 0
2 is the smallest prime number. The status of two as the smallest prime number is the reason that base 2 (binary) is the most efficient storage system available.
You have karate to use as a self defense system.
Numbers never end, therefore there is no smallest number only smaller than the last.But it depends on the number system that you are defining, and what you mean by smallest - is is smallest magnitude, or a number which everything else is greater than it. For example, if you are dealing with natural numbers [counting numbers: 1,2,3...], then there is a smallest number, which is 1. If you're dealing with integers, and you mean smallest magnitude, then zero would be your number, but all of the negative integers are less than zero. What if your system is 8-bit signed binary numbers (so the range is -128 to +127). So you need to be specific about what you are looking for.
Anko Itosu introduced karate to the Okinawa school system in 1915.

The smallest number of distinct vowels (vowel phonemes) in any language is two. It is generally accepted that the Northwest Caucasian language Kabardian has such a vowel system.
