Learning Japanese

Hello /lang
I'm planning to learn reading japanese, cause I want to understand these visual novels.
I'm planning to do

Hiraganas/Katakana -} Grammar -} Kanjis
Is that how I should go? And how long will that take, before I can read good japanese? I can practice 1-2 hours each day.

Potentially, depending on how stupid you are and how fast/well you learn, you could be looking at 3 to 5 years before you could grasp material necessary to ace JLPT 3 or begin to probe JLPT 2.
