TOHOSHINKI 2007 : Concerts

After sweeping major awards in South Korea, TVXQ flew to Japan for almost a year to do intensive promotions and gain a stronger foothold in the Japanese music industry, the second largest in the world. The year also marked the beginning of their second and largest Asia concert tour, the "2nd Asia Tour Concert 'O'" and later the 2nd Japanese live tour with the release of Five in the Black album. They also released consecutive monthly singles, which according to Oricon Style, helped raise their recognition in Japan with every release by 3% in 2006, increasing to 5% with every release in 2007. 14.1% of Japanese fans were female while 4.6% were male with age demographics between 10 to 40 years old.

The single "Choosey Lover" was released on March 7th, followed by "Lovin' You" which debuted at #2 on the Oricon charts in June, their first single to reach such a position in Japan. Closely following its success, the bubblegum pop tunes of "Summer Dream" became TVXQ's most successful Japanese single in 2007, debuting at #1 and with sales of 112,771 copies in a week. Their double A-side single "SHINE / Ride On" debuted at #2 on the Oricon daily charts in October. Japanese singer Koda Kumi collaborated with TVXQ for her 38th single "Last Angel", which was released November 7th and ranked #3 on debut; the song was featured in the movie Resident Evil: Extinction. The collaboration with Koda Kumi aided TVXQ in raising recognition among teenage males (58.0%) and men in their 30s (62.0%) of the group, which could grow to be a new fan base for the group. In the same month, their 14th Japanese single "FOREVER LOVE" also debuted at #3. In December, the title song single "Together" for the "Cinnamon" animation movie debuted at #2.

In early April, the members began hosting a weekly radio program called "TVXQ Bigeastation" on Japan FM Network channel, which is currently being aired on seven local FM stations. The group represented Korea on MTV's Video Music Awards Japan and won the 'Best Buzz Asia in Korea' award on May 26th, 2007. They were also invited to many prominent Japanese talk and music shows such as Hey!Hey!Hey! and Utaban during their stay.

In South Korea, the group released their first digital single entitled "여행기 (Yeo Haeng Gi)", along with "천년연가 (千年恋歌) (A Thousand Years' Love Song)", "하루달 (Day Moon)", "All in Vain", "한여름의 크리스마스 (One Summer Night's Christmas)" and "Evergreen" ; these were the only songs that were released in Korean during 2007. Evergreen was particularly special to fans because it was a song where the music was composed by group member Micky Yuchun and the lyrics written by group member Max Changmin. TVXQ's guest performances in concerts, such as 2007 DREAM Concert and Mnet 20's Choice Awards, appearances of Korean variety shows, and personal access to Korean fans through celebrity websites such as Iple and UFOtown, ensured that TVXQ still provided entertainment for the Cassiopeians. During a virtual presidential election by MTV Korea, the group was voted as the "President of the Republic of Korean Music" among thirty other candidates by netizens. Because of this win, MTV and Boombox declared December 23 as “TVXQ Day”. They were also appointed as the Korea's e-government ambassadors by the South Korean government to help boost the new system to the citizens. In Thailand, TVXQ had the highest foreign artists sales of 114,027 for 2007, while their single "SHINE" was #1 on the “Top 10 of No.1 on Year Chart 2007” charts by Channel V Thailand
