A man and a woman meet in an air raid. After leaving the shelter they talk for a moment on the nearby bridge and promise to meet there again in six months if both are still alive. A second air raid separates them before they learn each others’ names. They do both survive the war but circumstances prevent their meeting in six months, thus beginning What Is Your Name?, the most phenomenally popular Japanese movie of the post-war era, eventually lasting six hours in three separate episodes, and arguably the most popular movie in Japanese history given the difference in ticket prices between its appearance and that of Princess Mononoke. https://japanonfilm.wordpress.com/2021/02/22/what-is-your-name-always-in-my-heart-kimi-no-na-wa-1953/
