2. Upgrading the Facilities of the Daibiru Buildings and Damage Caused by the 2nd Muroto Typhoon

After the requisitioning of the Daibiru Buildings was lifted in 1952, they were restored to their former condition through renovation work, but as the construction of new buildings in that area began, our company made an effort to provide comprehensive high-quality office environments by upgrading our own buildings’ facilities and services.

From 1953 to 1954, the building interiors were painted, and the lighting was changed from ordinary bulbs to fluorescent lighting. In 1955, the window frames of the Daibiru-Shinkan Building were repaired, and the exterior tiles were replaced. From 1955 to 1956, the roof of the Daibiru-Honkan Building underwent major waterproofing renovations.

Furthermore, in October 1959, the company undertook major renovations of the air conditioning system, which had been pending for some time, but it was extremely difficult to renovate the existing building’s equipment due to its many strong earthquake-resistant walls. It was a major task that took Toyo Carrier Corporation eight months to complete, but it was finished on June 1, 1960, and the entire building was air conditioned from that summer onward.

The Daibiru Buildings, situated in a low-lying area, had previously been damaged by typhoons several times, and protective measures against storm surges had been implemented. However, the 2nd Muroto Typhoon, which struck Osaka on September 16, 1961, caused the sea level in Osaka Bay to rise rapidly, and the storm surge soon breached the barriers. The entire Nakanoshima area was instantly flooded. At the Daibiru complex, muddy water overflowed the sandbags, broke the glass of the first-floor windows, and poured into the buildings. The floodwaters reached the ceiling of the basement and were 1.5 m deep on the first floor.

As soon as the typhoon had passed, the company established a flood damage task force, and all employees were mobilized to begin recovery work. Emergency recovery work continued day and night, and within about a week, the buildings had been restored to a state that would not impede our tenants’ operations. However, it took about a year for all recovery and renovations to be completed. After that, extensive construction work was undertaken on new measures to protect against storm surges, such as the installation of bank vault-style storm protection doors and panels at each entrance, the closing of the shipping entrance on the north side of the Daibiru-Honkan Building and the use of reinforced concrete to block the north-facing windows on the first floor of the Daibiru-Honkan and Daibiru-Shinkan Buildings, and the installation of strong storm surge barriers around the basement areaway.

The damage from this typhoon caused the company to incur losses for only the second time since 1948, when it had incurred losses due to the special tax on homes and property that had survived the war, but fortunately, no lives were lost.
