I always wondered and now I decided to ask: is there any purpose of learning so many useless vocab words, even in lower levels? By useless I mean words, that I have never used before in my life and probably will never use in the future. Neither in my mother language, nor in English and for sure never in Japanese.
Such words as ship hull (船体), police box (交番）, shaved ice (かき氷）and some other words I never used before. So it’s very hard to remember them and I wonder if they have any relevance in further levels? And why do we learn them already in the first few levels where more common vocab would be more useful?
The only use I see for that mentioned vocab is that I can impress my girlfriend who studied 2 years for N3 and doesn’t know these words. And I just needed a few weeks Wanikani to learn them
