Guchol is now quickly becoming extra-tropical as it gets embedded in the baroclinic zone. In fact, JTWC has already given their final warning for Guchol; it is likely that JMA will give their final warning as well later this morning. For the most part, heavy rains that brought more than 100mm in many places in Japan yesterday has ended. However, gusty winds are still being reported in Southern Hokkaido as well as places in the eastern part of Tohoku Region in Honshu. High waves are still present as well along the eastern portions of Hokkaido and Honshu.

We'll have another update later this afternoon.
