Yes, Japan has its own patent system administered by the Japan Patent Office (JPO). Japan is a full member of the World International Patent Organization (WIPO) co-operating closely with the US Patent Office (USPTO) and the European Patent Office (EPO) for example. English language translations of Japanese patents are provided by the JPO, and these typically start e.g. JP7654321 for granted patents, though applications are sometimes hard to find. Japanese patents can be searched for on commercial patent database systems such as Relecura, Innography, PatBase and Thomson Innovation plus others.
