When you pair Wanikani with other Japanese studying resources (Genki, BunPro, Tae Kim’s guide to Japanese grammar, etc. etc.) everything will build together and help you recognize many different things over time.
I will warn you, at least with my copy of Genki (from years ago), they don’t always give you the Kanji for vocabulary in the beginning, but slowly integrate it into further chapters in the book. So at the beginning, you’ll use a lot of Romaji and hiragana/katakana (which helps with wanikani readings at least) A lot of beginning vocabulary in this book also pertains to school life because that is usually when people start using it, but I would still say it’s a very good book to start out with. The listening and writing exercises are especially good practice, and if you like Kanji you can get the Kanji workbook that goes along with it for more example sentences (it’s yellow).
Enjoy the journey!
