GKIDS Acquires North American Distribution Rights to “Lonely Castle in the Mirror”

Japan Academy Prize-Nominated Feature from Acclaimed Director Keiichi Hara To Receive Summer Theatrical Release



GKIDS, celebrating its 15th anniversary as a producer and distributor of award-winning and artist-driven animation from around the world, announced today it has acquired all North American distribution rights for LONELY CASTLE IN THE MIRROR. Directed by Keiichi Hara (Miss Hokusai, Colorful, The Wonderland), the film features animation from the lauded A-1 Pictures, and is adapted from the beloved novel of the same name by Mizuki Tsujimura.



LONELY CASTLE IN THE MIRROR held its International Premiere at the Rotterdam International Film Festival – marking the first time a Japanese animated feature was selected for the festival – and additionally had its US premiere at the New York International Children’s Film Festival. It was nominated for the Japan Academy Prize for Animation of the Year, and was released domestically in Japan in December 2022.

Hara worked with various past collaborators on the project, including screenwriter Miho Maruo (Miss Hokusai, The Wonderland), composer Harumi Fuuki (Miss Hokusai, The Wonderland), as well as acclaimed artist Ilya Kuvshinov (The Wonderland) for visual concept and castle designs. 

GKIDS handles North American distribution for Keiichi Hara’s previous feature films Summer Days with Coo (2007) and Miss Hokusai (2015). GKIDS will release LONELY CASTLE IN THE MIRROR theatrically in both its original Japanese language and an all-new English dubbed version this summer. 

The all-rights North American distribution deal was negotiated between GKIDS and NTV.

“We are thrilled to be able to work again with director Keiichi Hara” said GKIDS President David Jesteadt. “His latest film is a deeply emotional story about the private struggles we all go through, and the small yet joyous connections with others that make life worth living. I can’t wait for North American audiences to join us on a trip to the Lonely Castle in the Mirror.”
