This paper discusses some facts that were pivotal in the process of the introduction of Bluegill Sunfish, Lepomis macrochirus, into various places in Japan, however have not been considered in the existing literature. This paper points out that L.macrochirus escaped, and also was stocked, to the open water in Osaka as a result of experiments by a fisheries experimental station in the 1960s and early 1970s. In Shiga Prefecture too, the fish escaped into Lake Biwa as a result of experiments by a fisheries experimental station in about 1969. Neither Osaka nor Shiga are mentioned, by previous studies based on questionnaire research, as the prefectures in which L.macrochirus inhabited in the years between 1960, when the fish was first introduced into Japan, and 1979. In addition, anglers, who considered L.macrochirus an ideal game fish, stocked ponds and lakes in some prefectures with L.macrochirus in around 1970 on purpose to multiply the species. During this process, a network among not only local governments, fisheries experimental stations, and fish farmers, but also industries targeting anglers, such as fishing tackle makers and a magazine for anglers, was being formed, which however did not get established after all. These findings will contribute to enrich the basis of today's genetic research on the distribution of L.macrochirus in Japan.

This paper gives an account of Prof. Dr. Kinji Shimizu, the first president of Nagoya Institute of Technology, and his establishment of Nagoya Municipal Science Museum. After graduating from the Electrical Engineering Department of Kyoto Imperial University in 1923, Shimizu was impressed by the German Museum in Munich during his stay there as a student in 1932. It's the first time that he learned the education in cooperation with industries. Just after the Second World War, he became director general of the Ministry of Education. However, new education system given by the United States focused not on developing practical ability but on gaining the basic knowledge, which is contrary to what he expected. Then, he contributed to the establishment of the Japanese Society for Engineering Education, besides working as the president of Nagoya Institute of Technology in the earlier 1950s. His idea was supported by industries for the economic growth. Throughout his career, Prof. Dr. Shimizu was convinced that practical engineering education would benefit Japan, and wanted to introduce cooperative education between universities and industries, along the lines of the same system in Germany and the United States. With this vision he founded Nagoya Municipal Science Museum in cooperation with local industries and local government as his final achievement. The museum was completed in 1964.

Japan and the United States signed in 1968 a new atomic energy agreement through which US light-water nuclear reactors, including those of the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company, were to be introduced into Japan. This paper studies the history of negotiations for the 1968 agreement using documents declassified in the 1990s in the US and Japan. After the success of the Chinese nuclear test in October 1964, the United States became seriously concerned about nuclear armament of other countries in Asia including Japan. Expecting that Japan would not have its own nuclear weapons, the US offered to help the country to demonstrate its superiority in some fields of science including peaceful nuclear energy to counter the psychological effect of the Chinese nuclear armament. Driven by his own political agenda, the newly appointed Prime Minister Eisaku Sato responded to the US expectation favorably. When he met in January 1965 with President Johnson, Sato made it clear that Japan would not pursue nuclear weapons. Although the US continued its support after this visit, it nevertheless gave priority to the control of nuclear technology in Japan through the bilateral peaceful nuclear agreement. This paper argues that the 1968 agreement implicitly meant a strategic measure to prevent Japan from going nuclear and also a tactic to persuade Japan to join the Nuclear Non -Proliferation Treaty.
