Namino village is located in the highland on the east side of Mt.Aso and the village is in elevation between 600 and 900 meters. The highland includes extensive grassland which was used by farmers individually. There was a customary called "mizunagare" which ruled that grassland was affiliated to the field where rain water flows to. Major crops in the village were maize, rape, wheat, buckwheat, soybeans, small red beans, sweet potatoes and upland rice. Especially, maize and rape were widely grown. The most popular cropping system was consective cropping of maize and rape. The system was intensive in terms of land use, however, it was extensive in terms of plant husbandry. The yields of the system were rather low due to the reasons such as large field sizes, high elevation, summer draught and occasional damages of volcanic ash from Mt.Aso. Sizes of farmlands were remarkably large. According to statistics of 1950, the fields one hectare or smaller accounted for 15.1%, between one and three hectares accounted for 47.5% and three hectares or larger accounted 37.7%. Since grasslands were predominantly covered with high quality silver grass, it was suitable to keep livestock. Cattle and horse were pasterned on nearby grassland so that farmers could use them anytime for cattle tillage and other works. Cattle works were extended to plowing, harrowing, leveling, rowing, intertillaging and ridging. There were three different plows in size. Large plows were called "ichibansuki," medium plows were called "nibansuki" and small plows were called "sanbansuki." There were also three sizes of harrows, and farmers used them properly. That is, progressed cattle working system had developed completely by the late Edo era. By the end of Edo era, "go-shi," soldiers who defended Higo country against invaders, had become land owners. In 1989, 57.5% of total upland field was possessed by large land owners who had more than five hectares, although they only accounted for 14% of all farmers. On the other hand, 8.7 % of farmers did not have any upland field, and 33.3% of farmers had only one hectare or smaller. Since the land system was strongly biased for owners, small farmers tenanted upland fields and grasslands from land owners. Total areas of upland field and grassland were about the same in the village. There was strong correlation between ownership of upland field and grassland. As mentioned, yields of upland field were low, and rents were also lower, for example, from 25kg to 70kg by maize. However, even such low levels of rent were burden for farmers. There were many earnest breeders in Namino village, and they produced excellent Japanese Brown Cattle. In 1911, Kumamoto Prefectural Aso Agricultural School introduced breeding stock Rudee which had excellent genes, and the breeders in Namino crossed their cows to them. As a result, many excellent breeding stocks were produced, such as Mata, Daiichi-hatsumaru, Daini-hatsumaru, Soko, Ryuzuka, Kamawari and Taihou. In this study, those breeding stocks in Namino village were concluded as the origins of Higo Brown Cattle.
