A Japanese student has been traveling the world wearing a pregnancy simulator and inviting men to put on the 10 kg vest to feel the struggles faced by expectant women.

"I want my project to give men a chance to raise awareness of pregnancy and life," said Kota Hakoyama, a senior at Hokkaido University School of Medicine.

A native of Nagoya's Nakamura Ward, 22-year-old Hakoyama embarked on his journey in February last year. He visited China, Southeast Asia, the Middle East, Europe and South America before returning to Japan in May, using buses and trains to travel inland and staying in budget accommodation.
