Held annually in mid-May, the Ikebukuro Jazz Festival is a street event that colors the areas around Ikebukuro Station’s West Exit. Outdoor performances are held in the Ikebukuro Nishiguchi Park, in the front areas of Marui at Nishi-Ichibangai and of the Tower Grandia and elsewhere.
It is a two-day event filled with lots of fun and a wide variety of people performs, ranging from elementary school brass bands to professional performers.
