4) Geometric system in Japan
Which system is the best for your language among Geometric, Cursive and Half cursive?
Such an argument does not mean anything important. Yoshiaki Takebe explained as following.
The reason why the Geometric systems are absolutely popular in Japan does not depend on the superiority of the Geometric letters but the Japanese historical circumstance origined in Takusari system.
Looking abroad, the Cursive systems are still very widely in use in Germany and rather widely in the world.
Therefore, superiority of the shorthand system is not decided by any kind of visual letters.
Whether shorthand system is superior or not depends on a design how to adopt the characteristics of the language.
