During lunch, Suzume notices a huge column of smoke, emerging from the location where the abandoned resort is located, which no one else can see. She rushes back there and finds the man from earlier, who is struggling to close the door. Suzume helps him, and they manage to close the door. Due to the column of smoke falling, an earthquake hits a nearby area.
Suzume takes the man to her home, where he introduces himself as Souta Munakata, explaining he is a "Closer" and must locate and lock specific doors in abandoned places throughout Japan, to prevent a powerful supernatural "worm" from being released and causing earthquakes. As they talk, the cat from the resort appears and turns Souta into the chair he was sitting on. Souta, now a small, three-legged chair, chases the cat onto a ferry headed for Ehime, with Suzume following along. The cat leaps onto another ship as Souta tells Suzume that the cat is a "keystone", and that the worm was released after the keystone's removal from near the door.
After reaching Ehime, Suzume and Souta find social media posts from locals, who have photographed and named the cat "Daijin". With the help of a friendly local girl, Chika Amabe, they locate the worm again and close the door in the entry to an abandoned school. They stay at Chika's home for the night. The next day, after parting with Chika, they hitch a ride to Kobe with a kind woman named Rumi Ninomiya, who asks Suzume to babysit her twin children. In the evening, Suzume spots Daijin who leads her and Souta to an abandoned amusement park, where the worm is trying to emerge again from a ferris wheel. They manage to lock the door, and the worm disappears. Souta explains that the portal within the door leads to the Ever-After, a place where souls go after death.
After tracking Daijin to Tokyo, Souta asks Suzume to take them to his apartment. There he explains the legend of the worm Namazu, and that he is the last descendant of a family that, for many generations, had been responsible for locking all the doors that lead to the Ever-After. He says that there are two keystones that seal the worm: the western keystone has become Daijin, while the location of the eastern keystone is unknown. He warns that if the worm tries to emerge in Tokyo, it could cause an earthquake of the same magnitude as the 1923 Great Kantō earthquake. Suzume notices the worm emerging again, and the two follow it. The worm takes a huge form in the sky and the two fly over it. Daijin reappears and reveals he has passed on his function as a keystone to Souta. Souta suddenly turns into a keystone and Suzume reluctantly uses him to lock-up the giant worm.
Suzume wakes up at a shrine housing the Tokyo gate, where she sees Souta in the Ever-After, but is unable to enter the door. Daijin appears and Suzume gets angry at him and tells him not to come back. She visits Souta's grandfather, Hitsujirō Munakata, at the hospital, hoping to figure out how to rescue Souta. He explains that Suzume's ability to see the worm and the Ever-After through the doors, means that in some point in her life she entered the realm through one of the doors. Moreover, the doorway that she first used is the only place where she can re-enter the Ever-After in order to save Souta.
She decides to locate this specific door in her hometown in the Tōhoku region, which was destroyed in the 2011 Tōhoku earthquake and tsunami, where Suzume lost both her mother and home. On her way, Suzume runs into Souta's friend, Tomoya Serizawa, who wants to help her to find Souta, along with Suzume's aunt, Tamaki, who has been looking for Suzume to take her back to Kyushu. Suzume refuses to go back and jumps into Serizawa's car. Tamaki also jumps in and they to travel to Tōhoku. At a rest stop along the way, Suzume and Tamaki get into an argument, discovering that Tamaki is possessed by Sadaijin, the eastern keystone, who follows them for the rest of the trip. Tamaki takes Suzume to the ruins of Suzume's old house, where Suzume finds the old door and enters with Daijin and Sadaijin. Once in the Ever-After, Sadaijin changes its form and distracts the worm, while Suzume tries to wake up Souta, who returns to his human form. Realizing the consequences of his freedom, Daijin sacrifices himself to become the keystone and lock the worm permanently in the Ever-After.
While still in the Ever-After, they see a young girl from afar. Suzume realizes the young girl is herself, from 12 years ago. Suzume decides to give her young self the childhood chair that was given to her, by her mother as a birthday present. She assures her young self the chair will provide her with the strength to overcome the tragedy and continue to grow. The young Suzume becomes energized and decides to leave the Ever-After and return (in the past), leading to her being found by Tamaki twelve years prior. Suzume and Souta leave the Ever-After themselves (to the present), with Souta returning to Tokyo, while Suzume and Tamaki return to Kyushu, revisiting the friends Suzume made along the way.
