Even Japanese bikes do not come with tool kits. They used to, but the tools were junk. Now they come with a screwdriver and spark plug socket, still junk. I must have 50 pounds of Japanese tools in a bucket. There are a couple of usable items. The spark plug socket usually works. But the big deal is the screwdriver bits. Japanese bikes do not use Phillips screws, they use JIS (Japanese Industrial Standard) screws, that LOOK like Phillips. But using an American Phillips screwdriver will usually strip them out. Good quality JIS screwdrivers are very expensive in the U.S.
