Bottom line first: Java Jazz Festival is Indonesia's largest jazz festival, held 29–31 May 2026. The venue has moved from JIExpo to the NICE exhibition centre at PIK 2 in Tangerang Regency, with 11 stages and over 1,000 musicians. 1. Lineup highlights: The 2026 Special Shows include Jon Batiste (29 May), Ella Mai & Wave to Earth (30 May) and Daniel Caesar (31 May), alongside Jacob Collier, Raye and Tunde Baiyewu. 2. Tickets: Sold via the official site javajazzfestival.com in phased releases — early-bird and pre-sale tiers are cheaper, so watch for the announced on-sale time to grab early-bird passes. Popular Special Show slots may require separate booking or advance reservation. 3. Practical tips: PIK 2 sits northwest of Jakarta in Tangerang, about 1–1.5 hours from central Jakarta by car — consider staying near PIK 2 or allow plenty of travel time. May is the tail end of Jakarta's rainy season, so bring rain gear. After buying, check the official schedule and stage map.
