Student visa count for Naturalization?

A requirement for naturalization to Japan is to live in Japan for 5 years.

I have lived in Japan for 6 years, but 4 of those years were as a student. Many websites say that a student visa cannot count towards naturalization (so I would only have 2 years, not 6).

However, this lawyer's video [at 6:20] says that a student visa can count, as long as you've also worked full time for 3 years. This would mean that I could apply next year (3yr work visa + 2yr student visa).

Can time lived in Japan on a student visa count towards naturalization? Which is the correct answer?

Talk to someone in –@–±‹Ç and you'll get your answer straight there.

Ministry of Justice doesnft seem to have hard rules about this, but in consideration of substantiating that the applicant is capable of supporting themselves on a stable basis, they seem to consider gat least 3 years of full-time workingh as an appropriate gguideline.h

So one year later, youfd have been living in Japan continuously for 7 years, including first 4 years as student then the most recent 3 years working? Then that should suffice. (Some law firmsf websites say that you need to have 5 years working, but the g3 years workh seems to be applied to those who came to Japan to work then started working in Japan right after studying.)
