The Nara Prefectural Government said Monday that two hotels in the prefecture were built using false data from Aneha Architect Design Office.

The hotels are the Sun Hotel Nara in the city of Nara, and Sun Hotel Yamato-Koriyama in Yamato-Koriyama.

The hotels could collapse if hit by a 6-plus quake on the 7-tier Japanese seismic intensity scale, the prefecture said.

The Sun Hotel Nara, a 12-story building that opened Nov. 5., closed Friday.

The Sun Hotel Yamato-Koriyama, which was designed by a local architect and built by a local contractor, suspended business Sunday.
