When Mayumi Watanabe tells people what she does for a living, most struggle to hide their surprise, and not just because of her diminutive stature. As a truck driver with 23 years behind the wheel, she is one of a small but growing number of women coming to the rescue of an industry that is the beating heart of Japan’s economy.

“I can see they’re thinking, ‘How can such a tiny woman drive a big truck?’ ” Watanabe, who is 152cm (5ft) tall, told the Observer as she prepared for the busy run-up to the end of the year. “But I’ve always loved cars, so it felt natural to want to be a truck driver.”
