Important Announcement from BABYMETAL
http://www.babymetal.com/news/?id=28
Posted : 2018.10.19
Thank you for continually supporting BABYMETAL. We would like to inform you of BABYMETAL’s new beginning which will be effective starting this month’s BABYMETAL WORLD TOUR 2018 in JAPAN performances.
YUIMETAL had expressed her desire to return performing with the group in the following months after last December’s performance due health concerns. During her absence, both SU-METAL and MOAMETAL as well as the entire staff team had been preparing for her awaited return. However, YUIMETAL came to a decision that she will not be performing at BABYMETAL WORLD TOUR 2018 in JAPAN and that she will no longer be a part of BABYMETAL. We thank her for all of her contributions and wish her all the best in her future endeavors.
This month’s BABYMETAL WORLD TOUR 2018 in JAPAN will mark the rebirth in which SU-METAL and MOAMETAL form the core of BABYMETAL.
We would like to express our deepest gratitude to the fans for the continued support and look forward in what’s next for BABYMETAL.

I have been absent from BABYMETAL's recent concerts. I am truly sorry for giving trouble to many people.
I had thought again and again, but now it was decided that I leave BABYMETAL.
I am sorry that, deciding in this way, I am going to give trouble to other members and those who are supporting BABYMETAL. And I truly apologize for giving sorrow to our fans who are supporting BABYMETAL.
I had a strong wish to appear on the stage (of BABYMETAL) again, but I am not in perfect health even now and I have a wish to move forward to my own long-lasting dream, so I decided in this way.
I am grateful that I was given many precious experiences as a member of BABYMETAL.
They were such days that I felt I was blessed. When we all smiled and got united in our live concert, it was my joyful and happy time.
I endeavor to move forward so that you can see me again someday as Yui MIZUNO.
I truly thank you for (supporting YUIMETAL) for eight years.
Yui MIZUNO
しばらく欠席が続き、沢山の方にご迷惑をおかけして本当に申し訳ありませんでした。
何度も考え直したのですが、私はこの度BABYMETALを辞めさせていただくことになりました。
この決断でメンバーやBABYMETALを支えてくださっている方々にご迷惑をかけてしまうこと、申し訳なく思っております。そして、BABYMETALを応援してくださっているファンの皆様、悲しませてしまって本当にごめんなさい。
もう１度ステージに立ちたいという強い思いもありましたが今も体調が万全ではないこと、そして以前からの私の夢、水野由結としての夢に向かって進みたいという気持ちもあり、今回このような決断をいたしました。
BABYMETALとして、貴重な経験を沢山させていただき感謝しています。
私は恵まれているなと感じる日々でした。みんなで笑ってひとつになれたライブ、楽しくて幸せな時間でした。
またいつか水野由結として皆様にお会いできるように努力し邁進します。
８年間本当にありがとうございました。
水野 由結
Additional Information about This Matter
- According to several newspapers (2018 Oct. 20), Amuse Inc. say this doesn't mean her retirement from entertainment business.
- According to several tweets about the stockholders meeting of Amuse Inc. (2018 Jun. 24):
Some stockholder questioned why YUIMETAL was absent from BABYMETAL's tour and why Amuse Inc. didn't announce it officially, then Amuse's president answered that they had never commented and would never comment officially about the future of individual artists and what they could say for sure are Yui MIZUNO regained her health and she was still under contract with Amuse Inc.
Some other stockholder questioned whether YUIMETAL would come back to BABYMETAL's stage or not, then Amuse's president answered that Metal Resistance Chapter 7 was performed by different number of performers, it was an attempt and not permanent, and they neither affirm nor deny YUIMETAL's coming back. - In Sakura Gakuin diary [2018 Mar. 14], Miss Aiko YAMAIDE, a then member of Sakura Gakuin, wrote she made contact with Miss Yui recently, but she didn't mention Miss Yui's health though she loves Miss Yui so much. (She said sorry to Miss Yui for having lost the letter from Miss Yui in the backstage of TIF 2014, and Miss Yui answered she was happy to know Miss Aiko had carried her letter right up to the stage.)
- According to some fan's tweet [2018 Jul. 22], he met Miss Hana TAGUCHI, a graduate of Sakura Gakuin, the previous day, he asked her about Miss Yui, and she answered Miss Yui was fine.
- From [2015] to [2017], Miss Hinata SATOH, a graduate of Sakura Gakuin, said several times in her tweets that she took Amuse's acting lessons together with Miss Yui.
- Before Miss Yui joined Sakura Gakuin when she was 10 yr., she had appeared in some TV dramas and some stage drama as a child actress. Her own long-lasting dream may be to become an actress.
- According to several tweets about the stockholders meeting of Amuse Inc. on 2019 Jun. 23rd, an executive director of Amuse Inc. said that Yui MIZUNO's health condition was recovered (was being recovered?) and they were (she was?) preparing for her new dream.
