Lumajang Regency in East Java has experienced a significant rise in international tourism throughout 2026. Between January and September, the region recorded 113,642 international arrivals, with the Tumpak Sewu waterfall serving as the primary attraction, accounting for approximately 84.8 percent of total visitors.

While the tourism growth provides economic benefits to local transportation, lodging, and culinary sectors, environmental concerns have emerged in protected areas. Ranu Pani Lake within the Bromo Tengger Semeru National Park is facing significant sedimentation and shrinking water levels, with its area decreasing to approximately 4.8 hectares despite previous dredging efforts in 2025.
