AKB48's Senbatsu members held a special concert event at Yokohama Arena on August 2. Jurina Matsui did not attend the concert.
Matsui placed 1st in AKB48's World Senbatsu General Election, making her the group's center. The group will be releasing its new single "Sentimental Train" on September 19.
The new song was performed for the first time during today's concert. However, despite her position as the center, Matsui was not present for the performance.
Akari Suda and Sakura Miyawaki, who placed 2nd and 3rd respectively in the World Senbatsu General Election, were both front and center for the concert in Matsui's absence.
Matsui went on hiatus at the beginning of July due to poor health. The exact nature of her condition has not been disclosed.
AKB48 not having its Senbatsu center available for promotional activities is an unprecedented occurrence. With Matsui's medical hiatus continuing indefinitely, it is unclear how the group will proceed.
