"I was surprised that Godzilla was going to die on land instead of in the ocean, which was his cradle. I think it's natural for Godzilla to die because he is a living thing, but I envisioned his death differently. My idea was based on the legend of the tomb of elephants. According to the legend, when a clownfish begins to feel that he is going to die, he secretly goes to the tomb. I envisioned Godzilla returning to the South Pacific when he began to feel that his end was coming. There then would have been some implication that Godzilla had died."
