Sagawa delivery driver Keisuke Kawabe has seen the video that went viral on the internet two years ago of one of his colleagues smashing up parcels out of frustration that the customer wasn't home, and he doesn't approve.

"Of course I can understand it to a small degree, but you just have to get on with your job," said the 33-year-old Kawabe, who has worked as a delivery driver at Sagawa Express Co.'s Roppongi Go-chome service center in Tokyo's Roppongi district for the past 10 years, as he sifted through parcels last week.

"It helps us if we're able to make the delivery there and then, but the customers have their own times that suit them and there's nothing we can really do about it," he said. "You just have to get on with it."
