A hotel in Osaka run by the embattled inn chain Apa Group has failed to meet the required quake-resistance standard and was shut down, city officials said Wednesday.

This is is the fourth Apa Group building to be confirmed as defective.

Last month, the Kyoto Municipal Government announced that two of the group's hotels in the city did not meet required building safety standards. Earlier this month, an Apa Group condominium in Narita, Chiba Prefecture, was also confirmed to be defective.

The structural strength for the Osaka hotel was calculated by Toyama-based Tamura Mizuochi Sekkei, the same firm that did the calculations for the other three buildings.
