I agree with you - the only really "unique" Murakami works I've read are Hard-Boiled Wonderland (a mix of SF and fantasy), his non-fiction (especially Underground is good, a series of interviews with victims and perpetrators of the 1995 Aum Shinrikyo Tokyo gas attack), and After the Quake (even that one walks straight into "typical Murakami" territory sometimes).

I think it's one of the reasons why he won't get the Nobel Prize even though so many always list him as top contender, he's just too repetitive.
