Palaceside Building held an earthquake disaster response drill on the 1st, with about fifty people participating, centered on the Mainichi Building Co. office on the 5th floor, the B1 disaster prevention center, and the B6 central monitoring room.

This day marks the 1923 Great Kanto Earthquake 92 years ago and is "Disaster Prevention Day," when national and local government and the private sector cooperate on drills and other preparedness; Mainichi Building also holds training around this time every year.

The drill started at 10 a.m. on the scenario of a magnitude-6-lower earthquake. At the loud call "Training earthquake!!" everyone began, confirming procedures to start emergency generators immediately after a building-wide blackout. When shaking subsided, headcounts and safety checks were reported from Mainichi Building departments and partner firms — security contractor Aing, facilities manager Groove Ship, cleaning contractor Seibi — and at the same time the "Earthquake Countermeasures Headquarters" was set up with the Mainichi Building president as chief = photo. Facilities staff left to inspect the building per manual and that day's orders; the sales department checked tenants on each floor and the parking garage.

After that, the drill commander called successive simulated incidents — escalator emergency stop with injuries, people trapped in stopped elevators, a shopper pinned under a collapsed shelf on B1, cars colliding in the underground garage with foam discharge, fire from a B1 shop — and headquarters, the disaster center, central monitoring and field teams exchanged urgent reports, support requests and instructions by radio and internal phone while tackling initial firefighting, stopping sprinklers and foam, and transporting and treating the injured.

From 11 a.m. after the drill, a review meeting drew out not only what went well but also missed reports, incomplete instructions and slow response, confirming tasks ahead.

We reaffirmed that real disasters will not go like a drill, and that building management must keep repeating training and never let guard down.
