Measured in yen, the increase was less sizeable but still significant. Consumption rose from V5.4 billion in 1 to V7.9 billion in 1, an increase of 4 percent (table 5-. This increase was driven principally by continued growth in the automotive and machinery industries, as well as in domestic construction. Research and development Japan is among the world leaders in gear &. The Ministry of International Trade and Industry (MITI) Agency of Industrial Science and Technology (AIST) has an active Mechanical Engineering Laboratory. However, MITI and the Japanese Government have not requested any gear research recently. 9 The Japanese Gear Manufacturers Association (JGMA) does not fund or sponsor any gear research, except as might be required in developing product standards. 9 The government funds research at several university gear research centers including the University of Tokyo, the Laboratory of Precision Machinery and Electronics of the Tokyo Institute of Technology, Kyoto University, and Kyushu University, which has gear-making machine tool research laboratory. University research centers are usually very small, with teams of researchers dedicated to narrow research topics, such as noise or fatigue
