Godzilla vs. Megaguirus

Original: ゴジラ×メガギラス G消滅作戦

In an alternate timeline the original Godzilla is never defeated and repeatedly reemerges to feed on Japan's energy sources. A new inter-dimensional weapon called the Dimension Tide is created with the intent of eliminating Godzilla. However, the new weapon might also serve as a gateway to something far more sinister.
