Giant God Warrior Appears in Tokyo
What they share
Both films are directed by Shinji Higuchi, and they both carry the dread mood tag, and they sit in Action / Science Fiction territory. If that's the register that drew you to Lorelei: The Witch of the Pacific Ocean, the second film will land in a comparable space — through a different lens.

What Giant God Warrior Appears in Tokyo is
Shinjuku. Midday. A single shattered pane of glass. Colossal armored beings descend, blotting out the sun. Incandescent destruction follows. Hide your children. A brief, brutal kaiju tone poem in the mode of 1960s Toho.
