K-Pop boy band BTOB has begun their first Japanese concert in order to meet with their fans.

Yesterday and today, they held their The Secret Diary concert at the Tokyo Dome City Hall. They will be heading off to Osaka next week to hold two more concerts as well for a total of four concerts and meet with 10,000 fans.

During their Tokyo concert yesterday, they performed a variety of hit songs as well as special stages for their fans. The members also revealed what they thought was a ‘proposal’ among other activities during their two hour concert.

They previously held their Hello Melody live concert in Korea and received much attention for its diverse performance and events. In just six months, they are holding their first concert in Japan.

Although the members were busy with individual schedules, they still found time to prepare for their concert. Member Yook Sung Jae, who is currently filming for the drama, “School 2015,” flew straight to Japan for the concert yesterday after filming for the drama all night long.

Last November, the group released their Japanese debut single, “Wow,” and was able to expand their fan base in Japan.

In just four months after their Japanese debut, they released their first original single, “Future,” and sold 100,000 copies and ranked second on the Oricon weekly chart.
