Location
The prefecture faces the Pacific Ocean in central Honshu, and is blessed with a warm climate and rich natural
surroundings. Bordering Kanagawa prefecture with Mt. Hakone in the east, Aichi prefecture with Lake
Hamana in the west, and connecting with Yamanashi and Nagano prefectures with Mt. Fuji and the southern
Alps in the North. Running 155 km east to west and 118 km north to south, the prefecture has a total area of
7,780 km2 over 23 cities and 12 towns, and has a population of about 3.7 million people.

Of the workers in the construction industry, those aged 55 and over account for approximately 34% and
those aged 29 and under account for approximately 11%, suggesting progress in aging. This creates a big
problem in terms of passing skills on to the next generation. (2014)
