Part of Hideyuki Morimoto's internship at U.S. chemical giant DuPont's branch in Tochigi Prefecture involved preparing an experiment on engineering plastic. Although his mentor was watching over him, he still felt pressure to perform.

"Unlike studying, if I make a mistake, it would cause damage to the company," the 20-year-old student at National Institute of Technology, Kure College, in Hiroshima Prefecture said. "I have a responsibility as an employee and I am no exception."

Morimoto's 10-week internship at DuPont's Utsunomiya branch began in May and will end in July. By the end of the program, he will have participated in experiments and worked on quality management and design, capping it all off with a presentation in English.
