The 1970s and 1980s saw Japanese art continue in many of the directions begun in the 1950s and 1960s, but often with much bigger budgets and more expensive materials. As Japan's economy kept rapidly expanding, and eventually grew into one of the largest economic bubbles in history. With Japanese currency becoming incredibly strong in the wake of the 1985 Plaza Accord, Japanese individuals and institutions became major players in the international art market. Extraordinarily wealthy Japanese mega-corporations began constructing their own private art museums and acquiring collections of modern and contemporary art, and Japanese artists greatly benefited from these expenditures as well.
