Busan Metropolitan City (Mayor Park Heong-joon) announced that it will release two new 2026 episodes of the citizen documentary series “Busan Deokhu-mentary” through BusanTube, the City’s official YouTube channel.
“Busan Deokhu-mentary” is an interview-based character documentary series that portrays, with a cinematic sensibility, the stories of Busan enthusiasts who love Busan. With a total of six episodes across Seasons 1 and 2, the series has recorded a cumulative 2.89 million views, demonstrating the influence of citizen-engagement content. It also contributed to the City winning the top prize in the metropolitan local government YouTube category at the 2025 Social i-Award last year.
This year’s new series consists of two episodes. Episode 7, “Slow Bike (Super Cub) Enthusiast,” features the appeal of riding in Busan through Ms. Seo Mi-seon, a rider and YouTuber. Episode 8, “Migratory Bird Enthusiast,” tells the story of two middle school students, Park Sang-yun and Yeo Su-hyeok, who have continued birdwatching activities across the Nakdonggang Estuary.
The main character of Episode 7, Ms. Seo Mi-seon (screen name: Seo Nabi), is a YouTuber who introduces travel content while riding a “slow bike (Super Cub)” around various parts of Busan. Riding a bike with a top speed of about 80 km/h along routes where mountains, sea, and rivers come together, the episode warmly captures her journey of slowing down the pace of everyday life and rediscovering meaning and rhythm in life.
The main characters of Episode 8, Park Sang-yun and Yeo Su-hyeok, are middle school students who have continued birdwatching activities at Busan’s migratory bird habitats along the Nakdonggang River. To date, they have documented approximately 35,000 photos of migratory birds. In particular, last year they became the first to discover a Great-tailed Grackle, a species previously unrecorded in Korea, in Myeongji-dong, Gangseo-gu, Busan. They also observed and studied birds together with Dr. Park Jong-gil of the Korea National Park Service. This discovery is confirmed in an observation report published in the Journal of the Korean Ornithological Society, where the students are listed as co-authors. The Korean name for the Great-tailed Grackle was personally coined by Yeo Su-hyeok, who first observed the bird.
In Episode 8, “Migratory Bird Enthusiast,” viewers can also explore Busan’s distinctive natural scenery and the many facets of Busan as a global environmental city.
The Nakdonggang Estuary in Busan is a rich ecological habitat where the sea meets the river, and it is the nation’s top migratory bird site, with 150 to 200 species visiting every year. Through the birdwatching journey of Park Sang-yun and Yeo Su-hyeok, viewers can experience the appeal of Busan’s unique natural ecosystem and the value of Busan as a “global environmental city.”
Last year, Busan Metropolitan City won a Gold Award at the Green World Awards for the Eulsukdo ecological restoration project. The Green World Awards is an international environmental awards program hosted by The Green Organisation, a UK-based nonprofit environmental group founded in 1994. It is known as one of the world’s four major environmental awards and is also called the “Oscar of the environmental field.”
Starting today (Feb. 4) with the release of the main trailer, Busan Metropolitan City will present Episode 7, “Slow Bike (Super Cub) Enthusiast,” on Feb. 6, followed by Episode 8, “Migratory Bird Enthusiast,” on Feb. 17 as a Lunar New Year holiday special. The videos can be viewed on the City’s official YouTube channel, BusanTube (www.youtube.com/@Busan_is_good).
Meanwhile, to enhance the promotional impact of the content, the City produced “Busan travel board game goods.” The goods are naturally linked with Episode 8 of “Busan Deokhu-mentary” and are designed to allow users to experience Busan’s diverse attractions while enjoying the game.
A special cover was designed using Busan’s mascot “Boogi” and enthusiast characters, and the goods are composed of content featuring Busan travel routes.
In addition, in collaboration with the local brand BOOSTERZ, which designed character icons for about 50 attractions in Busan, the City produced the “Busan Deokhu x BOOSTERZ Busan Travel Board Game Edition” and plans to promote a goods event in March. More details can be found on the BusanTube channel.
Won Young-il, the City’s spokesperson, said, “Through the sincere stories of Busan enthusiasts, this series captures the charm of both a ‘fun Busan’ and Busan as a ‘global environmental city.’” He added, “We will continue to produce content that helps discover, through citizens’ perspectives, the value of a Busan ‘people would want to live in even if they were born again.’”
