If you’ve recently booked a room at the brand new Keio Presso Inn Kayabacho you might want to start looking for alternatives. The hotel, which just opened in August, has suspended operations amidst revelations that the building’s construction may not meet earthquake standards.

The Ministry of Land, Infrastructure, and Transport learned this week that Hidetsugu Aneha, the buildings architect, had falsified quake resistance data.

Aneha admitted to the falsification late last week, saying:

“I didn’t feel I was doing something wrong. I was too busy to feel that way.”

Aneha’s admission has raised questions about a number of other buildings the architect has worked on in recent years.

The 260 room hotel near the Tokyo Stock Exchange has been consistently full during the business week. The buildings owners plan to re-open the hotel should it pass additional earthquake inspections.
