Season totals (cm) from official JMA daily snowfall records at the Nozawa Onsen observation station, 46 seasons. Faded dots mark seasons with an incomplete daily record – their totals only include the days that were actually recorded, so they may understate the real season total. The dashed trend line is fitted across all 46 seasons, including the incomplete ones – as a result, it may be pulled slightly lower than the true long-term trend, since several seasons' totals are partial rather than complete.
