One Direction wants to "avoid embarrassing moments" in foreign countries in the future.
During a press conference in Tokyo, Japan last week band member Zayn Malik abruptly ran offstage holding his apparently raging upset stomach.
One Direction's other members Harry Styles, Liam Payne, Louis Tomlinson and Niall Horan were left to cope with an awkward interview.
To prepare for other international visits, the group will learn more about the country they're visiting beforehand.
"The press conference in Japan got embarrassing because the boys' culture shock was so obvious," a source told British newspaper The Sun.
"Over the weekend they vowed to learn at least 20 of the most common words in the languages of the countries they're visiting before they land there.
"They think it will avoid embarrassing moments and build up a bond with fans."
Although One Direction has amassed a fortune, the boys aren't hiring tutors.
Apparently they will rely on the Internet for instruction.
"They're just going to use YouTube tutorials to brush up on their language skills and think that's going to be enough," the source said.
