Territory context
Asia Pacific supplied the bulk of overseas gross. South Korea, Taiwan, Singapore, Australia, and New Zealand together contributed roughly $768,000, while the Russia/CIS release added $27,797.
European earnings were modest outside France. The EMEA total for the title is below $150,000, reflecting a limited theatrical rollout rather than audience rejection.
Comparison with Hosoda's later films
Summer Wars was Hosoda's breakthrough as a director of original theatrical anime. The 1.65 billion yen total more than doubled the 260 million yen earned by The Girl Who Leapt Through Time and set up the larger grosses of Wolf Children and The Boy and the Beast.
The film's 4K restoration in 2025, more than fifteen years after release, shows the enduring catalog value of the title even if the re-release added only a small dollar amount.
