Progress of the Cryptomeria japonica pollen front for 2013 was monitored at 95 sites, distributed from Kyushu to Hokkaido, by using a Durham sampler (86 sites) or both the Durham sampler and an IS-Rotary sampler (9 sites), to track the first day of pollen release. Results from the Durham sampler show that, early in February, the pollen front had reached southern parts of Kanto, Tokai, Kii Peninsula, western parts of Chugoku, and the whole of Shikoku and Kyushu. By mid February, the front had progressed from southern to northern areas of Kanto and Tokai, and also to the southern and northern regions of Kinki. By late February, the front had moved up to the southern and central regions of Tohoku facing the Pacific Ocean, as well as central Chubu and some areas of Hokuriku and northern Kinki. By early March, the front was observed in the central to northern regions of Tohoku that face the Sea of Japan, and to part of Hokuriku. While by mid March, the front had reached the northern area of Tohoku district. The front finally arrived in the southern part of Hokkaido by early to mid April.
