The measurement of unusual winter sprites in the Hokuriku area (Japan Sea side) was performed as a primary target of the 2006/2007 winter campaign by means of coordinated optical and extremely low frequency (ELF)/very high-frequency (VHF) electromagnetic observations. We have also added the same observations for the sprites in the Pacific Ocean, to be compared with the characteristics of Hokuriku sprites. The following results have emerged from this campaign: (i) the predominance of column sprites in winter has been confirmed not only for the Hokuriku area but also in the Pacific Ocean (with the probability just above 60%), (ii) carrots are much more frequently observed in the Pacific Ocean (with a probability of ~28%) than in the Hokuriku area (~16%), (iii) a very unique property of Hokuriku sprites is the surprisingly long delay (average ~90 ms) of sprites from their parent lightning flashes and the delays for carrots and columns exhibit some significant difference (80 ms for columns and 100 ms for carrots) and (iv) the time delay of Pacific Ocean sprites is much shorter (~43 ms average) than that at Hokuriku, but there is no remarkable difference in delay between carrots and columns. Finally we discussed the importance of time delay studies to understand sprite generations and their parent lightning discharges, because the difference of time delays on the Japan Sea side and in the Pacific Ocean are thought to be causally related to the parameters of parent thunderstorms.
