The Secret World of Arrietty is set for IMAX screenings in North America and Japan, with 4K remastered versions supervised by Studio Ghibli. The film is directed by Hiromasa Yonebayashi and adapts Mary Norton's novel.
The Secret World of Arrietty, directed by Hiromasa Yonebayashi, is a 2010 Studio Ghibli film adapted from Mary Norton's children's novel. It follows the borrower girl Arrietty, voiced by Mirai Shida, and the human boy Sho, voiced by Ryunosuke Kamiki. Hayao Miyazaki contributed to the screenplay and planning.
In 2026, the film received two IMAX screening announcements. GKIDS announced a North American one-day-only event on May 19, with the film newly remastered in 4K and presented in IMAX for the first time. Showings were available in Japanese with subtitles and English-dubbed versions. This continued GKIDS' partnership with IMAX, which had brought Kiki's Delivery Service to the format the previous month.
Toho later announced a Japanese release on August 7. The film will run concurrently with Whisper of the Heart at IMAX theaters nationwide from October 23 to November 2. A second window from October 30 to November 12 expands the 4K remasters to all 47 prefectures and includes Dolby Cinema screenings. The screenings use a 4K DCP format, though theaters without 4K equipment may convert to 2K. New poster visuals and trailer footage were published.
