On the 22nd March 2016, NHK Symphony Orchestra held a concert celebrating their 90th anniversary. The setlist consisted pop and classical music, and AKB48 Watanabe Mayu appeared for a special collaboration, singing “365nichi no Kamihikouki”.
Watanabe Mayu tweeted afterwards “I couldn’t sing at all…want to disappear. I really wanted to vanish. Goodbye.”
However, the conductor of NHK Symphony Orchestra Mogi Daisuke complimented “Eh? But it was great!? The difficult notes and lyrics were delivered well. You were great singing this infront of so many guests.”
Seems like her unhappiness was only a result of the high standards Watanabe placed on herself. On the Internet, fans commented “She’s really the type to aim high/Mayuyu is being strict on herself as usual/Without Takamina now, only Mayu can support the headquarters.”
In another article, a idol magazine writer revealed some background story about the concert.
“The entrance tickets for this concert was based on balloting, and the ballot deadline was 3rd March. At that point in time, Watanabe’s name was not included in the performer’s list. There were quite a few people who came to know about her appearance after arriving. They were fans of Ringo Sheena and Hatsune Miku who were originally in the performer’s list. Both their fans were not possibly a fan of Watanabe, and it’s also said that virtual and real-life idols don’t mix. Her appearance was not welcomed initially.”
“When her crystal clear voice filled the hall, the atmosphere changed. Those who came to watch Ringo Sheena and Hatsune Miku almost cried, and talked about having heard something valuable. The orchestra members also praised her dignified presence and smiles, noting the reasons why she is loved by many.”
“She tweeted about her unsatisfactory performance, but it was great that she remained dignified in a sea of fans who were not her own. Ringo Sheena and Hatsune Miku’s fans have talked about voting for her in the upcoming elections. That can be said to be the highest form of compliment.
This was a flawless performance.
