a country that tried and failed to get rid of Chinese characters

(1)Japan accepts Western culture as Meiji Restoration and is disillusioned with Asia
(2)I tried to abolish Chinese characters
(3)The government decided to set up a research institute and tried to speak Japanese in the alphabet for 20 years, but it was put on hold due to the judgment that there were too many limits
(4)After the end of World War II, Japan resumes research on abolishing Chinese characters
(5)I tried to digest Japanese in the alphabet again, but I failed again
(6)You can see how difficult it is for countries in the Chinese character culture to be independent from Chinese characters
