I really enjoyed the linked essay, but I think the playfulness with which e.g. Murakami can pick up English as a brush in a toolbox raises a lot of interesting questions about whether translation guilt is warranted. Doesn't appropriation work both ways? Would a bakery attack make any sense in a Japanese culture without European bread? And speaking of the idea of denatured business English... so many of Murakami's images, sounds and references get their charge by playing with the mixing of western and Japanese culture, both the corporate and the artistic/literary/musical sides of each. I see it as similar to what French impressionism and cuisine did with their Japanese counterparts, an expansion and exchange of culture without one necessarily eroding the other.
I can't actually find any reference to him saying this though.
