Otagroup has published a press release where it apologizes on behalf of the MetaGrandma Vtuber Hiroko, who provided an incorrect age during her debut in late 2022.
When Hiroko made her debut stream on December 7, 2022, she declared her age as 85 years old. However, she was actually 84 years old at the time and chose to be 85 for the sake of convenience.
The real person behind Hiroko eventually had difficulty tracking her age, so she wants to use her real age. That means instead of sticking around with 88 years old in December 2025, Hiroko would now use 87 years old, which is the same as her real age.
Hiroko has also published her own apology video in regards to her age on the MetaGrandma channel:
While famous Vtubers from groups like Hololive and Nijisanji mostly comprise people from younger generations, the MetaGrandma group consists of real grandmothers. Via the project’s official website, Otagroup requires new audition applicants to be at least 75 years old, residing in Japan, and not diagnosed with dementia.
As of 2025, there are 8 members in the MetaGrandma group—including Hiroko, who has the number #0. The latest one to join the group is the 76-year-old Okoto, who made her debut in August 2025.
