The streets of Shinjuku get a whole lot busier during the annual grand festival, known as a reitaisai, of Hanazono Shrine.
There will be many food stalls and festivities around the shrine, but the main event takes place on Sunday. Large mikoshi (portable shrines) will set off from the shrine in the morning (around 10 a.m.) and be carried through the main streets of Shinjuku. Depending on the year, the type of mikoshi and route changes.Organizers may cancel events, alter schedules, or change admission requirements without notice. Always check official sites before heading to an event.
