A Synthetic Estimate Of The National Wealth Of Japan 1885–1973

This article present estimates, in current prices, of the national wealth of Japan and of about a dozen components for twelve benchmark dates between 1885 and 1973, the distance ranging, with one exception, from five to twelve years. The estimates are derived by a combination of (a) Ohkawa's perpetual inventory estimates of reproducible fixed assets for the period from 1885 to 1940 and Economic Planning Agency censuses for 1950 to 1965, roughly extrapolated to 1973; with (b) estimates of other components of national wealth (land, inventories, consumer durables and net foreign assets) taken for the pre‐war period chiefly from census‐type data and derived for the postwar period from miscellaneous, mainly official, sources. As in most countries the current value of Japan's national wealth increased until World War II considerably more slowly than its national product, which expanded with extraordinary rapidity. In the postwar period, however, the ratio showed a slight upward trend reaching by 1973 fully 3 1/2. The ratio of all reproducible assets to national product showed a similar pattern at a lower level, reaching 2 1/2 in 1973. In contrast the ratio of so‐called productive assets (non‐residential buildings, equipment and inventories) failed to show a definite secular trend remaining between 1.5 and 2.2 at all but one benchmark date. Changes in the structure of national wealth over the past century were pronounced, but very different before and after World War II. Up to the 1940's, the share of land declined sharply from about one‐half to less than one‐fourth, to the benefit primarily of producer durables and non‐residential structures. In the last quarter of a century, in contrast, the extraordinary rise in urban land prices brought the share of land in national wealth back to one‐third (though the share of agricultural land continued to decline rapidly), while that of producer and consumer durables continued to increase.
