If the registered trademark has become famous in Japan, is there any additional way, other than the trademark registration, to protect the mark?
Yes, there are multiple ways to protect your trademark in case the registered trademark has become famous in Japan.
In such case, you may obtain Defensive Mark protection, which extends the range of your trademark right to goods/services beyond those covered by the trademark registration. In addition, it is also possible for you to get injunctions under the Unfair Competition Law.
