Why has Japan’s English education been confused for thirty years?

I read an article on PRESIDENT Online, which I sympathized with. It was a talk between Kumiko Torikai and Takashi Saito. I would like to excerpt some of their dialogue as follows.

Kumiko Torikai (from PRESIDENT Online)

-Adopting English private examinations for the University Standardized Test, which starts in fiscal 2020, have canceled at the last minute. Not only this, Japan has been confused about English education for thirty years. What is the cause? Kumiko Torikai points out that regarding the ability to speak English as English conversation is fundamentally wrong. -

Torikai: “An enormous problem of the series of English education reform is the relation with Japanese language becoming weaker. Mother tongue is important to study foreign languages, but they are trying to dismiss it. “
Saito: “Japanese in general have a complex about speaking English. Speaking English fluently is cool. Halting Japanese English is embarrassed. But is that an ability to test by university entrance examination?
Torikai: Exactly. Those who want to speak English fluently should make an effort to do so. But university entrance examination should test basic skills that studied in high school, especially reading skills.
Saito: Basically, systems should be improved gradually, and it tends to get good results. Current National Center Test for University Admissions includes listening test. So if the test will be improved, I think that they could measure students’ communication ability.
Torikai: I agree with you. There is no need to measure four skills separately. The four skills
should be learned comprehensively. So examination has to measure comprehensive ability. I don’t understand why speaking ability should be measured separately.

I felt relieved when I read the Torikai’s opinion. There were descriptions in a book that she wrote as follows. -According to a questionnaire, many companies need English writing skills. Because nowadays, e-mails are the mainstream rather than phone calls. Apparently, those who are very good at English are not always good at work. (H.S)
