Ah no, I would recommend the exact opposite. Focus your Japanese studies somewhere else (reading, listening, doing textbooks, learning grammar, writing, speaking, whatever floats your boat) and do WaniKani as a supplement to all that other stuff.
WaniKani is only meant to give you the ability to read Kanji and some more or less common words associated with these Kanji. You will never learn Japanese by focusing on WaniKani. It’s also really hard to learn the Kanji in isolation without having something else to anchor them to.
You need to supplement at least with some reading, some grammar study, listening, and some way to learn words that are Kana only/not on WaniKani.
Using Genki for all of that is a good idea as a beginner. But there are a lot of other resources you can use. The Ultimate Additional Japanese Resources List!
PS.: I expect you can already read and write Hiragana and Katakana relatively fluently, otherwise I would advise starting with that.
PPS.: It’s also important to no overwhelm yourself at the beginning. Trying something for 2 weeks and see if it fits is a decent strategy. In the beginning you have 2 important tasks:
- start with SOMETHING and don’t get parallized by all the conflicting recommendations and choices. You can always correct later even if you are not 100% efficient at first.
- Find out how you actually learn and what brings you joy with the language to keep going through the tough times
