A Chinese couple who took a toilet seat from their hotel in Nagoya, Japan has become the subject of heated online discussion.

According to a WeChat user, the couple, who was part of a Chinese tour group, took a multi-function toilet seat from their room. After realizing that the toilet seat was missing, the hotel contacted the group's tour guide and called the police.

Mr. Yang, with the Ningbo branch of Shanghai's Spring Travel, said that the couple was part of a six-day group trip to Japan, which included a stay at Toyoko Inn in Nagoya.

"They moved the two beds together and found the toilet seat under the bed. They thought it had been left by other guests who had stayed in the room, so they decided to take it with them," he said.

After discovering the missing toilet seat, the hotel called the group’s tour guide. 

"The tour group was on the way to another hotel. With the help of the tour guide, the couple mailed the toilet seat back to [Toyoko Inn]. They later sent a letter of apology," said Mr. Yang.

Yang said the hotel has opted not to press charges against the couple. The tour group is still in Japan, and will return to China on Oct. 22.
