Drinks giant Asahi Breweries booked Ryo Yoshizawa, who one fashion magazine said has “national treasure-class handsomeness”, for a commercial for its 3.5% Super Dry Dry Crystal beer.

But the 30-year-old, one of Japan’s most popular actors, returned home on Dec 30 perhaps having consumed something stronger.

Yoshizawa was “drunk” and “accidentally made his way into an apartment room next to his”, his talent agency Amuse said in a statement yesterday.

“I’ve lost my memories. I think I just went in without asking, because I wanted to use the bathroom,” Yoshizawa was quoted by local media as telling police.

“We have decided to terminate our contract” with Yoshizawa, Asahi Group Holdings spokesman Shiori Shimizu told AFP today.

“As an alcohol beverage company, we consider his actions unacceptable,” Shimizu said.

“We will no longer use him in our future advertisements,” she added.

Yoshizawa apologised to his surprised neighbour for the “major trouble he caused”, Amuse said, adding that the actor already vacated the apartment.

Like other countries, drinking has been declining in Japan, with low-percentage and alcohol-free beers – and even abstaining – growing in popularity, especially among younger people.
