The Next Anime Film From The Director of YOUR NAME is Titled SUZUME NO TOJIMARI and It's Coming in Fall 2022

Makoto Shinkai, the famous director behind Your Name and Weathering With You, has his first project in three years coming out in Fall 2022, Suzume no Tojimari (English title TBC). Here is the official synopsis:

Suzume, a 17-year-old girl who lives in a quiet town in Kyushu, meets a young man on a journey “looking for doors.” Suzume follows him to a ruin to a dilapidated building in the mountains and finds a free-standing, undisturbed door as if “it” alone were saved from devastation. Suzume feels drawn by an invisible power and reaches out to the door... Soon, doors all over Japan start opening one after another. The doors that opened must be closed to shut out calamity that lays on the other side.

—Stars, sunset, and the morning sky. The places she wanders into have a sky where all hours of the day seem to blend together—

Beckoned by the mysterious doors, Suzume’s “journey of closing doors” begins.

It sounds very metaphorical and given the director I would expect nothing less. You can check out the full press conference announcement about it below.
