In the 1960s, radio astronomy research in Japan was at a developing stage in comparison with that of leading countries. However, in the following decades the situation improved dramatically, and Japan gained a competitive position in this research field. This was achieved largely through the construction of the Nobeyama Radio Observatory (NRO). This paper describes the NROʼs construction history by focusing on the setting of scientific goals and development of the equipment to achieve them. Although there have been a few preceding studies on the Japanese history of modern astronomy including radio astronomy, it is characterized that this study utilized mainly the minutes of the Science Council of Japan and documents of research groups as primary sources. This paper clarifies the following processes. In the 1960s, with a series of major worldwide discoveries in radio astronomy, the importance of radio astronomy was recognized in Japan as well, which led to the planning of the Science Council of Japan. Responding to the global trend of radio astronomy, Japan set as the scientific goal exploring millimeter-wave astronomy. In order to meet the requirements, the 45m radio telescope and an acousto-optic radio spectrometer for spectral observations were designed and their specifications were actually realized, which far exceeded world standards at that time. Consequently, Japanese radio astronomy could obtain its global position.

Chii, the Japanese term for 'lichen', is widely used in contemporary East Asia. However, precisely when and by whom this term was first used to refer to lichen is not known. In addition, Japanese botanists from the 1880s to the 1950s had doubts regarding whether Chii was an accurate translation of lichen, given that Chii originally referred to moss that grows on the ground, whereas most species of lichens grow on barks of trees or on rocks. In this paper, the author shows that Li Shanlan and A. Williamson et al., in the late Qing dynasty of China, first used the term Chii to refer to lichen in Zhiwuxue, published in 1858. In Japan, Tanaka Yoshio, who was influenced by Zhiwuxue, first used the term Chii in 1872. However, further investigations led to the discovery that ITO Keisuke translated lichen as Risen in 1829. In 1836, UDAGA WA Yoan also translated lichen as Risen by using a different kanji (Chinese character) to represent sen. In 1888, in his article, MIYOSHI Manabu suggested a new equivalent term, Kisoukin, to refer to lichen (algae-parasitized fungi). In the article, he proposed the term Kyosei as the Japanese translation of symbiosis. Ever since the late 1880s, Kyosei has been used as the Japanese biological term for symbiosis.

This paper analyzes the distribution of the Subsidiary Fund for Scientific Research, a predecessor to the Grant-in-Aid for Scientific Research (KAKENHI), which operated in Japan from the 1930s to 1950s. It reveals that the Japanese government maintained this wide-ranging promotion system since its establishment during the war until well into the postwar period. Previous studies insist that, at the end of the war, the Japanese government generally only funded the research that it considered immediately and practically useful. In contrast to this general perception, my analysis illustrates that both before and after the war, funding was allotted to four research areas: natural science, engineering, agriculture, and medicine. In order to illuminate this continuity, I compare the Subsidiary Fund with another research fund existing from 1933 to 1947: the Grant of the Japan Society for the Promotion of Science (JSPS). The comparison demonstrates that the JSPS received externally raised capital from the military and munitions companies. However, while this group focused upon engineering and military-related research as the war dragged on, the Subsidiary Fund has consistently entrusted scientists with the authority to decide the allocation of financial support.

This paper examines how mass screening for tuberculosis was implemented in wartime Japan. A tuberculosis mass screening program for the entire Japanese population began with the National Physical Fitness Management System (1940). This approach reflected the latest theories in Japanese tuberculosis pathology that primary infection would develop into an active disease more frequently. Under the total war system, the mass screening program divided the population according to the status of tuberculosis infection and contraction, with a focus on the prevention of the disease in those infected for the first time. Those classified as “previously infected healthy individuals,” a term introduced for screening, were considered more desirable than the uninfected because they were supposed to have gained “immunity” to the disease after a certain period of time had passed since the primary infection. They were not only said to be the safest against tuberculosis but also as those who had overcome the danger of developing tuberculosis and acquired a strong body that could endure discipline and labor. This paper argues that the tuberculosis mass screening program emphasized the acquisition of immunity and that the new tuberculosis control system was built based on the concept of “previously infected healthy individuals.”

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 is to explain the process of the introduction of nutrias in Japan and the thoughts of various people who were related to it. Since nutrias was regarded as furred animals suitable for the wartime system and attracted the interest of the military, breeding of them was spread rapidly. However, the demand for nutrias furs was vanished by the defeat of WWII, then nutrias were ejected in the open air. At a later time, around 1950, breeding of nutrias became popular once again. But this boom was declined after several years and nutrias were ejected outdoors again because the boom did not expand beyond the stage of speculative business. This fact shows that in the historical context, the introduction and expansion of nutrias was not seen as a problem but even recommended, which is different from today's principle that any introduced species should be expelled. On the other hand, this paper can not confirm any fact showing the argument about the introduction of nutrias had some influence on the argument about what human society ought to be like. However, it shows that biologists have attempted to speak figuratively about nutrias by giving them various names, for example, shouri (this is a homonym of the word that means victory in Japanese) or rumin (this word means immigrants who are forced to wander in Japanese). This fact means that any discourse about the introduction of living things should become not only scientific but social.

The purpose of this paper is to identify who fabricated the three small Ikkanbari (一閑張) telescopes discovered by the author, and to estimate when these telescopes were fabricated from a historical perspective. Zenbei IWAHASHI (1756–1811) was one of the most famous Japanese telescope makers of the Edo period and fabricated many high-performance telescopes. After Zenbeiʼs death, his successors inherited his manufacturing technique and continued to fabricate Ikkanbari telescopes until the Meiji period. To date, telescopes fabricated by the IWAHASHI family have been investigated by the author, Makoto WATANABE and his colleagues, who have already identified 24 telescopes as having been fabricated by the IWAHASHI family. Most of these telescopes provided direct evidence of their origin, such as the IWAHASHI familyʼs original pattern Kuruma gata (車形), the inscription of the name IWAHASHI, and the IWAHASHI trademark. In this study, the author investigated three small Ikkanbari telescopes. There is no direct evidence that the telescopes were fabricated by the IWAHASHI family, except for one telescope that had IWAHASHI trademark on its case. However, the author concluded that a telescope can be considered as having been fabricated by the IWAHASHI family if its size is equal to that of the telescopes described in Saikutsumori-cho (『サイクツモリ□』帳) and if several of its patterns are the same as those of the telescopes known to have been fabricated by the IWAHASHI family. This result confirms M.WATANABEʼs opinion.
