Viticulture in Japan has many disadvantages. Firstly, and most seriously, it is high humidity during growing season. Because we have a lot of rain in July (flowering season) and September (just before harvesting), many disease problems occur. Especially, European varieties, which usually have thin skins and relatively small berries, are less resistant to powdery and downy mildews and bunch rot. Secondly, as soils tend to be acidic, soil amelioration is necessary. Finally, as each vineyard is small (average size of vineyard in Yamanashi is less than 1 ha/grower) and located on the steps, vineyard mechanization is difficult. Therefore growing good grapes in Japan is very labor intensive.
