On the 28th, Prime Minister Sanae Takaichi visited the U.S. Yokosuka Naval Base with U.S. President Donald Trump, who was visiting Japan, and inspected a U.S. aircraft carrier. She was seen jumping up and down in front of the U.S. soldiers, raising her arms in the air, sparking controversy.

When President Trump introduced her as "the winner" and "Japan's first female prime minister," Takaichi, with a big smile on her face, raised her arms repeatedly and practically jumped up and down in response to cheers from the American soldiers.

This scene was reported on television news as a symbolic one, and became a hot topic on the Internet, with related words such as "US military base" becoming trending words.

"The Japanese Prime Minister is having fun on an aircraft carrier inside a U.S. military base," "She's certainly having a bit too much fun," "Does she feel like she's at a concert?" "She's just a bunch of high school girls who are excited to meet their idol," "SHe is just ashamed as a Japanese person," "It's shameful," "She's making a fool of herself," and "It's a national disgrace," were some of the harsh criticisms that followed.

On the other hand, there were also comments such as, "It's a way of expressing herself that Takaichi thought carefully about her position," "It can also be seen as her acting after instantly understanding the time, place, and occasion within the U.S. military base," and "A little bit of an overreaction is necessary."
