President Donald Trump's trip to Japan was not without its awkward and cringe worthy moments, something that has become de rigueur for any outing by the commander in chief.

The most guffaws was provided by Trump's fish feeding activity Monday along with his Japanese host Shinzo Abe, and which sparked off a frenzy on social media.

On the second day of his five-nation tour of Asia, Trump stood beside a pond brimming with colorful koi carp with the Japanese prime minister in the Akasaka palace in Tokyo and fed the fishes in the pond. Trump was feeding the fishes when Abe emptied the box of fish feed in his hand and Trump followed suit, which made Abe and others present smile.

The incident drew funny reactions on Twitter as some blamed Trump for suddenly pouring away all the food inside the box to the fishes as it is harmful for the creatures to eat a large quantity of food at the same time. However, the video shows Trump just following Abe's act of feeding.

One user tweeted: "Shinzo Abe was feeding fish one by one, Trump f**k off pouring all of it."

It was not just the fish feeding activity, but some of the statements made by Trump during his Japan trip also caught the media's attention.

While urging Japan to purchase U.S. military technology, Trump said that Japan could shoot down North Korean missiles out of the sky. Trump said Abe would be well-equipped for an attack from North Korea.

"He will shoot them out of the sky when he completes the purchase of lots of additional military equipment from the United States," Trump told a press conference Monday.

"He will easily shoot them out of the sky, just like we shot something out of the sky the other day in Saudi Arabia, as you saw," Trump added, reports said.

The micro-blogging site users were prompt enough to pick up this line and react to it.

While meeting with Japan's emperor Akihito Monday, Trump did not bow; instead the president stooped and slightly tilted his head as a mark of respect to the 83-year-old leader, reports said.

Bowing is an important sign of respect in Japan, but it has also been criticized back at home as critics say the act is considered as appearing less powerful. In 1994, the then President Bill Clinton bent forward with his hands together to meet Japan's emperor at the White House. During that time, one White House official said "Presidents don't bow, and Emperors don't toast."

Trump also indulged in his favorite sport while on the trip, and enjoyed a golf session with Abe on Sunday. The two leaders played with Japanese professional Hideki Matsuyama at a championship golf course outside of Tokyo. Trump had also posted a short video on Twitter.

Trump also didn't shy from commenting on issues and events happening back home, and made categorical statements in reference to the Texas church shooting that took place Sunday.

Trump said Monday he believed the shooting was caused by a "mental health problem," and not because of problems with domestic gun laws.

When he was asked whether the U.S. gun control measures could have contributed to the Texas shooting, the president replied: "Mental health is your problem here."

"This isn't a guns situation," he said, before adding, "This is a mental health problem at the highest level. It's a very, very sad event."
