    Epidemiological records were not reported before the discovery of the causative agent Schistosoma japonicum. The first comprehensive epidemiological survey was conducted in 1911. Out of 69,131 patients, 7,893 were recorded to have a high infection rate of 11.4%. Countermeasures for snail control since 1909 when the intermediate snail host was discovered are historically divided into three stages. The first stage was from 1913 when the life history of the parasite was elucidated to the end of the World War II in 1945. In 1916, Yamanashi Prefecture provided funds for the systematic control of the disease including snail control. In 1924, molluscicides of lime were introduced. In 1932, the Japanese government created a law to support parasite control. The second stage was from 1946 after the end of the World War II to eradication in 1996. During occupancy, the United States army started surveys and instructional programs. Na-PCP was introduced and used until 1971 when it was incriminated as a water pollution agent. Starting in 1950, cementing of rice paddy ditches was shown effective so an official fund of 11 billion yen was provided until 1985. In 1996 Yamanashi Prefecture finally declared the area safe with cessation of the epidemic. The third stage was from 1997 when the disease was not reported anymore and vigilant activities continue to examine possible infections from the snails till date. Now the snail survives and even proliferates in the Kofu Basin without infection.

    日本に現存する所謂風土病の1つである日本住血吸虫症は,医的事象を通じての地域研究の対象として,ふさわしい性格をもっている.本論では,日本住血吸虫症の医学地理学的研究の第1段階として,その分布の偏在性を明らかにしたのち,ミヤイリガイの生態を考慮しながら分布規定要因を,生息地の自然環境条件,特に地形,土壌条件から検討した.
    生息地の洪水地形分類の結果,3種に類型化されたが,多くの生息地は,そのうちの1つすなわち洪水時に湛水し,而も湛水深が深く,湛水期間の長い低所である.この場合には洪水地形分類が分布状態をうまく説明することがわかったが,母も大きな分布範囲をもつ甲府盆地の生息地の場合は扇状地性の地形面に属するものが多く,洪水地形では説明できない.また同一地形区内でもミヤイリガイの分布は偏在している・そこでカイの分布を説明する他の要因すなわち土壌条件をとりあげることにし,採集地別,母材別,粒径別,腐植含量別等の土壌の比較をするために調整した実験土壌によって,ミヤイリガイの飼育実験を試みた結果,土壌が分布規定要因の1つであることを確かめた.

    1. The extermination of Oncomelania nosophora (Robson) by means of a soil-burning flame thrower is a very effective method provided that the use and operation are appropriate. The standard method for ordinary geographical terrain is 4-minute buring per 5m2, promising termination of more than 80 per cent.
    If deposits and stones are not found in the area to be cleaned, 2-minute combustion per 5m2 can provide a sufficient effect. On the other hand, when the area contains many stones destruction by fire for 6 minutes or more per 5m2 is necessary. In the case of the area containing flowing water or swamp, the effect of this method is not promising at all.
    2. The destruction rate reaches its maximum on the third day after the soil burning.
    3. From the economic point of view, the performance of this method is comparatively expensive, therfore, it should be used as an adjunctive of other principal method of Oncomelania extermination.

    The main endemic areas of schistosomiasis japonica in Japan were three sites in Yamanashi Prefecture, Hiroshima Prefecture and Fukuoka/Saga Prefectures, and ubiquity of distribution is governed by the intermediate host Oncomelania nosophora. The presenter has to date, undertaken to clarify these factors that govern distribution through the implementation of local surveys and breeding experiments. In Japan, numerous direct and indirect eradication measures were implemented immediately after the discovery of O. nosophora. These measures resulted in the declaration of safety being made in relation to the Kofu Basin in 1996, and in Japan, schistosomiasis was thought to have ended. However, since O. nosophora still inhabit the Kofu Basin, etc. the monitoring of habitation status is important. Consequently, with regards to the Kofu Basin, working with habitation density distribution maps from the end of the 1960s and around 2000, GIS was used to clarify the range of distribution and changes in habitation density. From Japan's satellite images, paddy fields were isolated, and by combining the range of risk areas with various maps, the areas that should be monitored for O. nosophora were isolated. We are currently establishing more effective monitoring systems by implementing local surveys using GPS remote sensing using satellite images.

     The development process and usage patterns of second-home areas at the foot of Mt. Fuji are clarified by analyzing their expansion process, capital, and owner behavior. After World War I, in 1929, Fuji Kyuko Company, profiting from a business boom, started to develop a second-home area south of Lake Yamanaka [Yamanaka Kohan Bessochi]. This approach, by which a private company borrowed a section of Imperial Gift Land from Yamanashi Prefecture and established a second-home area, served as a model for developments at the northern foot of Mt. Fuji. In the early 1960s, second-home areas were developed north of Lake Yamanaka and at Fujizakura Highland south of Lake Kawaguchi. With the opening of the Chuo and Tomei Expressways in 1969, there were large capital flows into the creation of up-scale second-home areas at Juriki Highland, Fujigamine Highland, and Asagiri Highland, as well as around Lake Kawaguchi from the late 1960s until the mid-1970s. Large railway, trading, and paper manufacturing companies, as well as local developers, started to create second-home areas throughout the high-growth period. These investors, therefore, competed for land at the foot of Mt. Fuji. As a result, speculative capital flowed into development projects in second-home areas. This speculation created the potential for massive environmental destruction. Consequently, local governments concluded agreements with second-home owners' associations to clarify management responsibilities. Owners are most frequently at their second homes on weekends and during summer vacations in the hot months from mid-July to mid-September when temperatures at the foot of Mt. Fuji are below 30°C. Owners also visit frequently at weekends and holidays in the spring and autumn. The second-home areas around Mt. Fuji, therefore, are both summer and weekend resorts, because they are located within a two-hour commute from Tokyo by car. The second-home areas, moreover, receive many migrants from urban areas, including aged persons, who seek an attractive natural environment at a relatively low price.

    Distosomiasis japonica is one of the principal endemic diseases in Japan. The distribution of morbidity shows Yamanashi Prefecture with an annual average of 52 cases, Shizuoka 2, Hiroshima 2, Fukuoka 2 and Saga 3 based on Statistics for the years 19331937. Morbidity in Japan from October 1944 to September 1945 was 1723; Yamanashi had 979 cases (57% of the total), Saga 395 (23%), Fukuoka 324 (14%), Hiroshima 25. The morbidity district of the Kofu Basin in Yamanashi Prefecture is at the confluence of the Kamunashi, Fuefuki and Ara Rivers. The morbidity sections of greatest density in this district are Mimachi, Futakawa and Asai, (all showing more than 24.48%), Okamata, Showa, Yamashiro, Inazumi, Surni-yoshi (Showing 15.9%); Tamahata, Tatomi, and Imasuwa also exhibit high rates. Although the morbidity on the delta of these rivers is at a high rate, arround the Circuiiference of the basin low rates are found. The dis-ease also breaks out on the delta at the confluence of the Ashida and Takaya Rivers in eastern Hiroshima Prefecture. Morbidity districts of the greatest density in this area are Kannabe with an average annual case rate (1949-1951) of 36, Miyuki 23, Yuda 1.0, Senda 6, Michiue 4, Nobeyania 3, and Nakajo 3. The morbidity districts of the Chikugo River in Fukuoka Prefe-cture are Kurume with a 1950-1951. average of 14 cases, Miyanogin 27, Agi-saka 19, Kitano 5, Umata 10, and Miwa 5; those of Saga Prefecture are Tosu 60, Kisato 22, Fumnoto 6, Tashiro 2, and Asahi 6. The Lake Inba district on the delta of the Tone River shows very low morbidity.
    Distosomiasis japonica spreads according to the pathogenic complex of Distosoma japonicum, Katayama nosophora and the human body. The attack rate varies with age and sex; 12% in age group 11-15, 11% in age group 16-25, and 9-10% for those above age 26. In Saga Prefecture morbidity by sex is 78 for men and 17 for women. The body length of the male of Distosoma laponicum is 16mm while that of the female is 22mm. The body width of the male is 0. 6mm; that of the female is 0.3mm. The eggs, excreted from the human body, grow into Miracidum and enter Kata-yama nosophora of the intermediate host. The length of Katayama noso-phora is 4_??_9mm and the diameter is 1_??_3mm. The snail lives in slow, stagnant streams of the delta; it cannot live in places affected by tides. The parasitic rate of Distosoma japonicum in the.snail varies from place to place in Saga Prefecture; Takada exhibits a rate of 32 0, Maki 38%, and Kisato 43.4, %. Temperature, surface configuration, agricultural practices and the cultural level are important factors amounting for the geographical distribution of the disease. Morbidity in Japan in 1950 was 918 with August 240 (26%), September 156 (17%), July 1.15 (13%), and October 105 (11%). These four months accounted for 67% of the annual morbidity. In winter months the rate is low, the grouch of Distosoma japonicum requiring tempe-ratures of 20_??_35°C. The monthly coefficient of correlation of morbidity and temperature is +0.723. Swampy districts are important geogens, Kata-yama nosophora living in those districts with numerous rivers and lakes such as Lake Inba of the Tone delta, the Kofu basin, the Ashida and Taka-ya deltas and the Chikugo delta. Pathogenic complexes result froir, culti-vation of paddy rice fields in which men work with bare limbs. A high cultural level leads to the destruction of pathogenic complexes while low cultural levels aid their formation.

    A 33-years old female was referred to our hospital with the diagnosis of acute peritonitis, unknown origin.
    Hematological date showed the leucocytosis with neutrophilia, the slight decrease in platelet count (10 × 104/mm3), the severe decrease of serum fibrinogen (89mg/dl), and the moderate increase in serum FDP (10μg/dl), bleeding time (9min.), coagulating time (15min.), the culture of the blood resulted in no growth of bacteria, but Limulus test was positive.
    Our diagnosis is sepsis at the beginning, but we found small ulcer covered black crust at her right leg, and established Tsutsugamshi disease by serological test.
    The patient was completely recovered by the therapy with tetracycline, but this clinical course was abnormal, so we reported this case, and studied about a state of occurrence of Tsutsugamushi disease in Gunma prefecture, and investigated about new type of Tsutsugamushi disease in Japan.
