Donald Trump's triumph in Tuesday's U.S. presidential election has turned books and masks related to the real estate tycoon into the hottest-selling items in Japan.

Rubber mask maker Ogawa Studios Inc. said Friday it received around 1,600 orders for its Trump mask in just over a day since election ended.

"Orders have kept flooding in since just before his victory was announced," said Takahiro Yagihara, senior managing director of the Saitama-based firm. "We can't keep up with the orders. We are making our customers wait."
