Also sodegawara 袖瓦, *tonemarugawara 利根丸瓦, tonegawara 利根瓦. Lit. "cylindrical sleeve tile." A sleeve tile used at the rear of the hanging tile *kakegawara 掛瓦 that is laid on a barge course *keraba 螻羽, drooping verge *minokō 箕甲 of a Japanese shrine or temple building. One side of the tile is longer than the other to compensate for the difference between the curve of the roof and the curve of the barge course. The tile also closes the gap that would otherwise exist if ordinary semi-cylindrical tiles *marugawara 丸瓦 were used.
It is not clear when the definitive shape for sleeve tiles evolved. Even at Himeji-jō 姫路城 (17th century) in Hyōgo Prefecture, true sleeve tiles are not used. Instead one semi-cylindrical tile and a part of another *dakimarugawara 抱丸瓦 are joined to bridge the gap created by the change in level between the first concave roof tile *tonehiragawara 利根平瓦 and the second concave tile *hiragawara 平瓦. However, there is no doubt that sleeve tiles were in common use during the Edo period.
