About 4.3 times as much in Kanazawa
For 1991–2020, the January precipitation normal is 256.0 mm at Kanazawa and 59.7 mm at Tokyo. Kanazawa's figure is about 4.3 times Tokyo's, a difference of 196.3 mm. These are city station values, not prefecture-wide totals.
Precipitation is not snow depth
Precipitation measures water from rain, snow and other forms. Kanazawa's 256.0 mm cannot be read as the depth of snow lying on the ground. The agency lists precipitation, snowfall and snow depth separately.
Tokyo gets about 3.1 times as much sunshine
The same table gives 62.3 hours of January sunshine in Kanazawa and 192.6 hours in Tokyo, roughly 3.1 times as much in Tokyo. Together, precipitation and sunshine give a fuller picture of the winter contrast. Monthly normals still cannot tell you the weather on a travel date.
