Share
Jungkook of BTS was born on September 1st. Every year, ARMYs around the world prepare celebratory advertisements for this day. "Can individuals also place celebratory ads?" "How much does it cost?" This article answers these questions.
What are Jungkook's celebratory ads?
Jungkook (real name: Jeon Jung-kook), born on September 1, 1997, is the main vocalist of BTS. Celebratory advertisements (saeng-il ads) are a culture where fans contribute funds to celebrate their favorite idol's birthday or anniversary with street ads and station signage. Originating in Korea, this practice has now seen numerous examples in Japan, especially in Shibuya, Harajuku, and Ikebukuro, every year. Jungkook's birthday is September 1st. It is recommended to plan your preparations backward, aiming for mid-August.
