Korean idols have one of the biggest global presence in the world of music. With the constant demand for more songs and reach with their international fans, K-Pop idols have taken to singing their songs in various languages, especially Japanese. Check out the idols who struck gold in Japan with these 8 songs.

Jet Coaster Love is such a fun song! Not only is the PV entertaining but the song is quite fun, too! It keeps the classic style of KARA and fuses it with the fun, quirky appeals of Japan. Another cute charm is the girls poking fun at the lyrics "Hara Hara" as they resemble member Gu Hara's name. KARA is one of the leading girl groups in Japan and this song is one of many the girls have slewed out over the years.

This song soared them to the top in more ways than one. Not only was this song absolutely addictive, it was even featured as the ED song for popular anime "Blue Exorcist." The familiar voices paired with the catchy instrumental make it pure ear candy! This song reached new heights of popularity alongside 2PM. Check out their unique live performance video!

BTS have received endless amounts of popularity this year, so it comes as no surprise that Japan has a huge crush on them as well. The boys released a soft, refreshing ballad and they show they have the power to dominate the Japanese music scene, too. Check out their live performance with Korean subs.

The song is quite the gem for B1A4 fans as the song was composed by member Jinyoung himself. The sweetly written ballad and cute winter setting make for a perfect Christmas song that Japanese fans and international fans can enjoy.

Without a doubt, of course one of Korea's biggest idol groups would revamp Japan with their style and bring some sweet songs along with them. The girls are like delicate but stylish ladies with their supreme fashion sense in this warm ballad.They also revamped some of their hit songs like "Gee," "Mr. Taxi" and more, which made the girls also establish a powerful presence in the Japanese industry.

This song is another notable Japanese release. The members of B2ST not only excellent sing their Japanese lyrics, they also capture that trendy and fierce electric sound found in many popular Japanese songs. Not only that, their simple dance steps make it easy for all fans to learn.

Big Bang is another iconic group breaking the barriers in Japanese music. This song really shines as the Japanese lyrics still bring out the adored sounds of Big Bang's music style. I'm confident many agree that G-Dragon could sing in gibberish and still sell a million albums.

BoA seemed to leave her mark in many music scenes. This song doesn't do as much justice to her vocals due to the electric auto-tune sound similar to a Japanese vocaloid. However, the song is still catchy to the ears and the PV makes for a personal experience through BoA's travels.
