[4][5][6] The story takes place in early Meiji era when large-scale shore-based whaling was still in operation along the Japanese Islands.
One day, the boss of fishermen declared that he will give his myōseki and properties and land and daughter Toyo to the person who succeeds to capture the whale.
[7] Yonesaburo Tsukiji was originally appointed for the tokusatsu filming of The Whale God, however he was suddenly appointed for the 1962 film The Great Wall (jp), and Toru Matoba (jp) instead became a tokusatsu director for The Whale God.
[8] Although not strictly depicting a fictional monster (kaiju), The Whale God was the first Daiei Film production to feature a rampaging megafauna.
[12][13] The Dai-kaiju, the right whale-based kaiju with an alias of "Whale God" from GeGeGe no Kitarō franchise, which is by Shigeru Mizuki and later yielded connections to the above-mentioned Daiei tokusatsu franchises due to Mizuki's involvements in Yokai Monsters,[14][15] was presumably influenced by The Whale God.
