Aichi Prefecture has a population of approximately 7.5 million, ranking fourth in Japan after Tokyo, Kanagawa, and Osaka. As the heart of the Chukyo metropolitan area, the population is concentrated in the western Owari region, centering around Nagoya City. Meanwhile, the Mikawa region, including cities like Toyota and Okazaki, also plays a prominent role as a center of industrial activity.
Economically, Aichi ranks third in the nation in gross prefectural product and second in per capita income, showcasing a very high level of prosperity. The prefecture boasts a well-balanced industrial structure centered on manufacturing and holds the top spot in Japan for industrial shipment value (¥48 trillion annually), a title it has maintained for 45 consecutive years.

Geography and Regional Composition
Geographically, Aichi is broadly divided into the plains of the western Owari region and the mountainous areas of the eastern Mikawa region.
-
Owari Region (Western Aichi): A highly urbanized area centered around Nagoya City. It is the political and economic heart of the prefecture and features a well-developed transportation network.

While the land area of each of these three regions is roughly equal, over 70% of the population is concentrated in the Owari region.
Climate Characteristics
Aichi generally has a Pacific Ocean-side climate with the following features:
-
Summer: Hot and humid, often oppressively so. Inland areas frequently experience extreme heat.
-
Winter: Dry and sunny, but the “Ibuki Oroshi”, a cold seasonal wind, can make it feel quite cold.
-
Snowfall: In the western part of the prefecture, snow clouds from the Sekigahara area of Gifu Prefecture may bring heavy localized snowfall.
-
Northern Eastern Mikawa and Northeastern Western Mikawa: Due to elevation, elements of Central Highland climate are also present.
Because of these geographic and climatic variations, lifestyle and agricultural practices differ by region and season within the prefecture.
