Visa Question

I want to go to Japan for a year to study Japanese at a language school. They used to require 12 years of study (high school), but I don't have that. I recently spoke with Go Go Nihon and they told me this:

Unfortunately, one of the requirements to apply for a student visa and enrol in a course lasting six months or longer is a secondary school/high school/upper secondary school diploma. Currently, the only schools that evaluate long-term applications from students without this qualification are the following:

1 – Intercultural Institute of Japan 2 – Tokyo Galaxy 3 – ISI Japanese Language School

As the Japanese Immigration Department is becoming increasingly strict, it is necessary to have studied at least 150 hours of Japanese at the time of enrolment, which must be demonstrated by submitting the course certificate/JLPT.

So they no longer strictly require 12 years? Or how does it work?
