"Dear fans: The actress Mana Kinjo, who belonged to our company, died from an illness on December 1st aged 25 years old. We pray for her soul to be happy in the next world. As of last year she had been taking time off, and she was trying her best to be able to return to work, but it wasn't to be. We would like to express our sincerest thanks to everyone who has supported Mana Kinjo and who has supported us. We are truly grateful. Although she was awkward and inexperienced*, she worked hard and faced challenges directly. We hope that you won't forget her smile as she headed towards her dreams."
* This isn't meant negatively - it's almost always included in notices like this as it's not considered polite in Japan to be too boastful about oneself or, in this case, someone who worked for you / that you were associated with
