The types of repair work undertaken may be itemised as follows: repair of structural members (including damage to structural elements such as columns, beams, walls and floors and water proofing failures); external repairs (including leakage of water on the balconies and repair of handrails, and clothes-drying platforms); internal repairs (including fittings, wooden partitions, tatami floor matting, window panes, shelves, walls, ceilings, locks etc), repairs of fixtures (including sinks, washstands, water pipes, lavatories, dust shutes etc). The structural repairs merit particular attention. For example, the main reinforcing bars of the columns and the beams in the Nikkyu company flats were exchanged and they were enlarged, and the same was done in building No. 30 in 1954. (See Fig. 3-1, 2)

For further information about everyday repairs, see Table 3-2, based on the surviving records of the Building and Repair Department, where repairs from June, 1972, to December 1973, are listed according to building and job. Although such limited data does not allow us to generalise confidently about repairs in all the buildings during this period, the following points are noteworthy: generally the buildings facing the sea and iron elements were the most frequently repaired, and the breakage of windows occurred more often in the common spaces than elsewhere.
