The Gion Festival's Nagatoboko (Shimogyo Ward, Kyoto City) began "assembling the float" on July 9, 2025. To allow time for safety measures, the start was one day earlier than usual.

The assembly of the float is the process of assembling the float's components, which are usually disassembled and stored, in time for the festival. Work on the float, including other floats, usually began on July 10. This year, the Nagatoboko float decided to start work one day earlier than usual to ensure time to set up scaffolding and safety nets to ensure the safety of the craftsmen and passersby.
