An inspection of the gas pipes in the Meisei 56 Building in Shinjuku where 44 people died in a Saturday morning fire has ruled out the possibility the blaze was triggered by a gas explosion stemming from corroded pipes, Tokyo Gas Co. said Monday.

"We have determined that the fire was not caused by gas leakage," the company said.

There were no cracks in the pipes or any other irregularities other than a gas meter that was found detached from a gas pipe.
