Godzilla Minus One description:

Feeling as if he unfairly cheated death too many times, Shikishima, a surviving Kamikaze pilot, is attacked on Odo Island along with many war plane engineers by a gargantuan monster. After the engineers die because of Shikishima failing to distract the monster, an overwhelming amount of guilt weighs on him, especially after a homeless woman and a baby move into his home when he returns. Shikishima, now on a personal mission, teams up with a large group of veterans to finally take down the monster known as Godzilla.
