Doesn't look like any Tokai case I've seen - more like the Gibson LP Standard cases (might be by the same Canadian company who do the Gibbo cases). Nice case, anyway!
Edit: The headstock shot there shows the bone nut off in all its glory. I've never seen a Korean Tokai with anything but a plastic nut.
Another other tell-tale sign is the control cavity covers - only the Japanese guitars have black covers on the switch rout/controls rout. (Look for that on the pics of the reverse).
On top of that - the angled body pic seems to show the bridge posts going straight into the body. For all the nut replacement, TRC replacement, control cavity cover changes, pickup replacement etc you can perform to hide a Korean instrument, this is the dead giveaway that you cannot fake: this guitar is Japanese
Korean bridges, like the Chinese ones, screw into metal bases on the body. The Japanese instruments screw straight into the wood.
Here's an example of a Korean ALS-48:

Easy to spot the metal bushes at the base of the bridge screws.
