Pollen Season
Cryptomeria pollen dispersal starts when average daily temperatures reach 10 degrees Celsius, partly depending on wind and terrain. Like the cherry blossom season, the pollen season moves from south to north across Japan, and from lower to higher elevations as spring progresses. For western and eastern Japan (including Tokyo and the surrounding KantÅ region) this means the hay fever season starts between end of January and mid-February. The cryptomeria pollen season peaks in the second half of March - first half of April in these areas, then declining over the following six to eight weeks. Japanese cypress pollination lags cryptomeria by about a month. Some people are more sensitive to one of the two pollen types and therefore may experience allergic symptoms earlier or later than others.

Famous quotes containing the words pollen and/or season:
“Books are the bees which carry the quickening pollen from one to another mind.”
—James Russell Lowell (1819–1891)
“Let us have a good many maples and hickories and scarlet oaks, then, I say. Blaze away! Shall that dirty roll of bunting in the gun-house be all the colors a village can display? A village is not complete, unless it have these trees to mark the season in it. They are important, like the town clock. A village that has them not will not be found to work well. It has a screw loose, an essential part is wanting.”
—Henry David Thoreau (1817–1862)
