In 2017, Kim made headlines when he opened Kave Mall in Shibuya, Tokyo. Although the five-storey building appears to have since closed, when it was still running, it housed Kim’s various businesses such as Cafe de Kave and Lounge Kave, as well as a selection of Korean brands that he curated.

In a 2017 interview with Japanese magazine Josei Jishin, Kim shared that he had planned the business for two years and contributed to the mall’s whole design, from the interior to the tableware.

Its grand opening was a big success, and Kim expanded his business by opening Kave Cafe in Osaka in 2019. Many of his fans showed up when the star made an appearance at the opening event.

However, it seems that Kim’s business was one of many affected by the pandemic, as Kave Cafe Osaka closed its doors in June this year and there have been no updates on its official social media pages since 2019.

G-Dragon’s fashion brand Peaceminusone

G-Dragon did not only make a name for himself with his music, but with his sense of style as well, which he channelled into his fashion brand Peaceminusone in 2016. Whenever he’s spotted wearing a piece of clothing or an accessory, he causes it to sell out or get a price hike, so his influence is obvious.

Demand for his own brand went through the roof, with certain exclusive products going for eye-popping prices on the resale market. Peaceminusone and Nike collaborated to create Air Force 1 trainers in 2019, called Para-noise. Their retail price was around US$200 – but they were re-sold for around US$10,950, about 60 times more, according to JoongAng Daily in 2020.

G-dragon was also the first K-pop star to be listed in the Business of Fashion 500, in 2015, for being “one of Asia’s most popular and paparazzi-hounded celebrities”.

BTS member Jin’s restaurant Ossu Seiromushi

Jin once said in a 2020 Wall Street Journal interview that his “family is all in business” … and Jin himself is apparently included in that statement, as he opened the Japanese restaurant Ossu Seiromushi with his brother Kim Seok-joong in 2018.

Like many other restaurants, Ossu Seiromushi couldn’t avoid taking a hit from the pandemic. On radio show Bae Cheol Soo’s Music Camp in September 2020, Jin confessed that his brother “sold his car to keep his business, so I’m worried about these difficulties”, which prompted many BTS fans to visit the restaurant and show their support.

Jay Park’s upcoming soju business

Jay Park wears many hats: he is the founder and CEO of record labels AOMG and H1ghr Music, and a former member of the group 2PM. The popular hip-hop artist continues to aim high with his future projects too – even if they have nothing to do with music.

With the hope that soju would become globally popular, he further shared his ambitions in 2019 on the talk show Radio Star saying that he also plans to retire from showbiz in around 2022 to focus on producing for a K-pop idol group and starting the soju brand, which he has named Won Soju.

While fans might be sad to let him leave the music world, it’s definitely exciting to see what he will bring to the table next.
