Zakka means "various things" in Japanese and it refers to an attitude in life where one tries to find beauty in the mundane. Part of the philosophy of zakka is an aesthetic sensibility towards kitsch, retro, cute objects that are also full of hidden meaning for the owner.
Not every zakka shopkeeper starts as a zakka lover. Bunkaya Zakkaten modestly means cultural and variety store, and is a big hit in Japan as a place to get all sorts of knickknacks. The Hong Kong store's shopkeeper, Boris Wong, was never a zakka fan before heading the store. Wong used to be an electric technician.
