A day after her tragic passing, new details about Rina Matsuko's death have begun to emerge.
On February 7, Matsuno was supposed to participate in a concert with her group Shiritsu Ebisu Chuugaku. However, due to poor health, she stayed at home instead to rest. Throughout the day, the idol is said to have appeared fine, and there was no cause for alarm.
Matsuno's parents were with her while she was at home resting. At approximately 5am on February 8, her parents noticed that something unusual was happening with her daughter and called emergency services.
An ambulance rushed Matsuno to the hospital for emergency treatment. However, by the time she arrived at the hospital, the idol had already lost consciousness. She was found to be dead upon arrival.
According to officials, Matsuno's parents are despondent at the loss of their child. While a funeral has not been set up, the parents intend to hold one at a later date.
Matsuno's sudden death has brought to light previous incidents of her recent poor health. On December 22, 2016, the singer wrote a blog post explaining that she had skipped the recording of "Ebisu " that week due to her poor health. With her health said to have recovered soon after, the post did not catch people's attention at that time.
Despite earlier incidents of poor health, Matsuno was generally seen as looking healthy and full of life. This remained true even the day before her death when she posted a photo on Instagram showing off a bright smile while on vacation with her family this past weekend.
The members of Shiritsu Ebisu Chuugaku are said to be in a state of shock over the loss of one of their group mates. Aside from a previously scheduled concert in Taiwan on February 18, the group's activities have been put on hold, with future activities currently in limbo.
