I can't upvote this enough. I have a degree in physics, but even so every year around this time for about the past decade I pay more attention to the literature prize, waiting for him to get recognized. The last chapter of Colorless Tsukuru hit me so hard I cried, and immediately went out of my way to get an autographed copy. His novels have certainly helped me transition into adulthood, and I think he definitely deserves the prize.
I wish I had a reaction as emotional as yours, but I still understand your sentiment. They're quirky, yet so relatable. Ultimately, Haruki literature resonates with the loneliness felt in the cold, detached 21st-century society.
Yeah, I just happened to read that last chapter of Colorless Tsukuru at the right time in my personal life where I could relate directly to just about every sentence, and at the end I just felt empty in a satisfying way, if that makes any sense. Then again, I find that with age I'm becoming more susceptible to melancholic or sappy fiction, even if it's not particularly well done (as in the case of some TV shows).
