J. Mark Ramseyer, Liability for Defective Products: Comparative Hypotheses and Evidence from Japan, 61 Am. J. Comp. L. 617 (2013).
Abstract: Americans file 80,000 product liability suits a year; Japanese file perhaps 100-300; and most countries more closely resemble Japan than the United States. Based on reports and articles from forty-five countries, Mathias Reimann has advanced several thoughtful and subtle hypotheses about this contrast. In this article, I apply Reimann's hypotheses to Japan and explore what they might tell us about law in the two countries. As Reimann suggested, the reason for the Japanese-American contrast does not lie in legal doctrine: on the substantive law of products liability, the United States and Japan are quite close. Instead, the reasons for the contrast seem to turn on aspects of American procedure that encourage meritless demands. Litigation rates are not lower in Japan because the law prevents victims from recovering their damages; Japanese law does not deter valid claims. Instead, the rates are higher in the United States because American law helps claimants collect amounts to which they are not legally entitled.
