2014–present: Return to Korea
Park returned to Korea as the members of g.o.d had agreed to reunite for their 15th anniversary in 2014. He re-signed with SidusHQ, which also manages g.o.d. Since g.o.d's reunion, he has been utilizing his graphic design background in contributing to the production of their concerts, providing artwork for background visual effects and designing concert posters.
Park made a cameo as himself on MBC drama You Are My Destiny, which starred his long-time friend Jang Hyuk. In their scene, Jang's character enters rapping the opening verse of g.o.d's debut song "To Mother" in an exaggerated manner, a tongue-in-cheek reference to him starring in the song's music video. He and fellow K-pop stars Sunny from Girls' Generation and Jackson Wang from Got7 joined the cast for the second season of Roommate, a reality television series in which various celebrities share a house and are responsible for all household chores and meals. The show was not renewed for a third season due to low ratings despite the new additions being well-received.
Since returning to Korea, Park has largely been cast in various variety and reality shows such as Infinite Challenge, Saturday Night Live Korea, Radio Star, Life Bar and others, having gained popularity with audiences due to his cheerful persona and candidness. He also appeared in the music videos for "Shake That Brass", the title track of singer-rapper Amber Liu's debut EP Beautiful, and "Hot Sugar" (뜨거운 설탕), the comeback single of Kim Jong-kook's group Turbo.
In July 2018, Park opened a YouTube channel called Wassup Man featuring himself video blogging his travels in Korea. The videos began going viral on social media in South Korea and the channel had nearly 900,000 subscribers within two months. Based on data compiled by YouTube of the most viewed and popular videos in South Korea, Wassup Man drew the most South Korea-based subscribers within the shortest period of time during 2018. In 2020, Wassup Man was adapted as a Netflix series titled Wassup Man GO featuring Park in Los Angeles.
Park made a return to YouTube in 2024 by co-hosting the talk show BYOB with fellow Korean American entertainer and Fly to the Sky member Brian Joo. Due to its content centering around food, the videos were uploaded on the YouTube channel "JohnMaat" (존맛), a Korean food-focused YouTube channel notable for frequently featuring English-speaking entertainers and chefs based in South Korea. The casual format, diverse line-up of guests and Park and Joo's frequent interchanging of Korean and English made their talk show popular among both domestic and international fans.
In October 2025, Park and Jang began starring in their own reality show Park Jang Bros: Call Us Anytime, which airs on the cable channel Channel S Plus and features the duo attempting to fulfill various requests sent in from members of the public. The Korean title 박장대소 (park jang dae seo) is an idiom meaning "burst into laughter" and is a wordplay on their respective surnames (Park and Jang).
