McDonald's Japan posted a cryptic visual on its official X account on the 19th, teasing, "This year's Shaka Shaka Potato features this guest! Y," instantly sparking a buzz online.

The revealed image shows a black silhouette of a female figure with long twin tails extending to her feet—strikingly similar to Hatsune Miku.
Fans quickly reacted with comments like:

"Leek salt flavor confirmed!"
"I woke up to this… it’s finally happening!"
"I have no idea who it is (sarcasm)."
"Miku’s silhouette is just too iconic!"
"They’re obviously going to shake it up!"
"It’s so obvious, I can’t stop laughing!"

As of February 20, 4:30 PM, the post has garnered 330,000 likes, making waves across social media.

Later that day, McDonald's Japan officially announced its first-ever collaboration with Hatsune Miku and Shaka Shaka Potato. In celebration of "Cat Day (JP: 猫の日, Neko no Hi )" on February 22, four renowned animators have created an original video featuring Hatsune Miku with cat ears shaking fries, titled ＃ミクとシャカろ. Additionally, the company hinted that something special might happen on March 9, also known as "Miku Day."
