How much of the land in Japan is good for agriculture? I would like a relative region, e. g. North, south, northwest, etcetera.

About 15-20 percent is suitable for Agriculture in which the majority is from the North which accounts for about 10-12 percent.

Japan is an island country and it is affected by currents most of the time. These currents cause severe typhoons which hamper a mass agricultural production in the country. This is why Japan relies heavily on imported food products.

i disagree that there is little difference between adult female development and adult male development. sociological studies comparing female and male pathways to adulthood, revelead that there are sustancial differences between them. particularly, female and male differ from timing of marriage, when they began to live with children and the likelihood of combining wife/husband and parent roles.
