Japanese author, male protagonist, mind bending

This is a popular book I'm pretty sure is written by a Japanese author that won awards for this book. It follows a male protagonist that going through something rough. The cover is either purple or red, pretty simplistic with a very geometric silhouette of a man with bottom upper case text that also gives a rigid feel.

Haruki Murakami seems like the most obvious author guess. His award-winning books are:

1979: Gunzo Award (best first novel) for Hear the Wind Sing
1982: Noma Literary Prize (best newcomer) for A Wild Sheep Chase
1985: Tanizaki Prize for Hard-Boiled Wonderland and the End of the World
1995: Yomiuri Prize (best novel) for The Wind-Up Bird Chronicle
1999: Kuwabara Takeo Prize for Underground
2006: World Fantasy Award (best novel) for Kafka on the Shore
2006: Frank O'Connor International Short Story Award for Blind Willow, Sleeping Woman

I second that. It must be by Haruki Murakami. There are also those red-white-black geometric cover editions of his works.
His protagonists are mostly male and going through something rough. 😄 From the 'mind bending' you have given I'd guess the most likely candidates are Hard-boiled Wonderland and the End of the World, Kafka on the Shore or The Wind-Up Bird Chronicle. But they all fit, apart from After Dark, which has female protagonists, and his short story collections and non-fiction.

Silly question, perhaps, but did you read the book in English? There's a set of yellow-and-purple covered editions of Murakami's works, and Hard-boiled Wonderland features a purple silhouette of a man, but the title isn't in English. (The uploaded cover image is poor enough I can't figure out what the language is, just that it isn't English).
