You have to be careful with this route. If you decide not to pursue your degree in Japan then you are stuck with only SPM and Japanese language which is of no use in UK/US/ANZ. If you have A levels/STPM/etc, at least you can still apply for unis in other countries.

For this route you need to spend a lot just to study Japanese language either in JP or Malaysia. If you decide to do it in JP you need to pay for your living expenses as well.
