Okaki Farm is in Suzaka City, Nagano Prefecture.Suzaka City is located about 30 minutes by car from Nagano Station.The city’s main industry is agriculture. It is one of the largest producers of grapes in Japan because the climate of the region is ideal for growing fruit especially low temperature at night.Plants photosynthesize and accumulate sugars during the day, but at night they consume the sugars they have accumulated and breathe them in. The region has low nighttime temperatures, which makes respiration and and transpiration inert, minimizing the consumption of sugar stored in the fruit.
As a result, grapes of the same variety can be grown with more bright and delicious than those produced in other regions.
