Large seiches occurred in Kyushu and its peripheral areas in February and July, 2009. Nakai and Hashimoto(2011, 2012) reported that slight atmospheric pressure changes played very important roles for the seiches. Like the examples of 2009, seiches occur locally in limited areas in many cases. On the other hand, seiches occurred throughout Japan in November, 2004 and January, 2005. The authors analyzed the propagation direction and speed of slight atmospheric changes by F-K spectrum for these cases. Slight atmospheric changes propagated almost eastward and crossed the Japanese Islands quickly in 2009. But they propagated along the Japanese Islands to the northeast direction for a long time in 2004 and 2005. The propagation directions of slight atmospheric pressure changes affect the sea areas where seiches occur very much.
