TL;DR: I started learning Japanese from zero five months ago. I now know the kanji and vocab up to WK level 20, and I’ve read or skimmed most of Japanese the Manga Way, as well as browsing various online resources from time to time. I’m about to start reading ARIA and Yotsubato as soon as they arrive. Would I still benefit enough from Genki to justify buying it, or is there too much overlap with what I’m already doing?
Long version:
In 2009 I visited a friend in the US. At the time I was an avid go player and had been toying with the idea of learning Japanese just to access the wealth of go material. One of my friend’s friends happened to know Japanese, and before I left she surprised me with a gift: a copy of Japanese the Manga Way. I loved the book at first sight, but I wasn’t ready to commit to the seemingly gargantuan project of learning the language. I’ve always hated memorization with a passion, and it was hard to imagine a project requiring more memorization than learning Japanese. Still, the book was in many ways one of the most wonderful gifts I’ve ever received, and over the years I occasionally felt a little guilty that it was collecting dust on my shelf.
Then in 2022 I fell madly in love with a woman who has a Master’s degree in Japanese, and I started thinking about learning the language again. In late August I tried Tofugu’s kana tutorials and found that learning hiragana was much easier than I expected (I hated memorization so much that I hadn’t really tried it after leaving high school some 20 years ago). Then I decided to try this Wanikani thing, one thing led to another, and now here I am, 147 days and 40491 reviews later, deep down the rabbit hole with a lifetime membership. Help!
Now I’ve read most of Japanese the Manga Way and skimmed the rest, and I’ve also browsed a variety of online resources (Tae Kim, imabi, WK forums, various blogs, etc.). Rather than mastering one grammar point before moving to the next, my strategy so far has been to get an overview of basic grammar as quickly as possible so that I could start reading native material ASAP, even if it’s very slow at first. Then I can gradually master the grammar I’ve skimmed by looking things up as I need them to understand what I’m reading (and I know what to look up because I can recognize grammar points that I’ve skimmed).
So far it seems like this is working, and I’ve learned way more in five months than I expected. When I started I only knew a few phrases and a bunch of go terminology, and now I can read NHK easy news, even if it’s slow!
Would it still be a good idea to go through Genki (or some other beginner textbook), or will I end up learning most of that if I continue on my current trajectory? My impression from googling is that JtMW covers more grammar than Genki, so I shouldn’t be missing out there, but many people seem to find Genki useful for the vocabulary and phrases. Originally my goal was just to learn how to read Japanese, and that’s still my main goal at the moment, but now it seems like I might visit Japan with my girlfriend in the not too distant future. I’m guessing that Genki covers stuff that’s useful for a tourist that you might not run into while reading news or manga. (My girlfriend is near native so I don’t actually need to know any Japanese, but I think I’ll get more out of the trip if I can use the language myself.)
