Animelo Summer Live has run at Saitama Super Arena every year since 2005, always in late August. The 2026 edition, “Messenger,” ran July 10 to 12 at Makuhari Messe instead, a one-year move forced by redevelopment work on the home arena, with Saitama already booked to host again in 2027. It follows the 20th anniversary edition in 2025, which drew a record 87,000 fans on the strength of the milestone lineup. Losing the venue and the calendar slot in the same year is the first real test of how much of that draw depends on the ritual rather than the lineup.
