Filler or gap-fill tiles used to close or plug the openings along the base of the main ridge *ōmune 大棟, the corner ridge *sumikudarimune 隅降棟, and various types of descending ridges *kudarimune 降棟. Gaps are created where the broad, concave roof tiles *hiragawara 平瓦 and the semi-cylindrical tiles *marugawara 丸瓦, meet the ridge. There are two types of filler tile: The *kanimendo gawara 蟹面戸瓦 is used to fill the relatively symmetrical gap made under the main ridge. The tile used to fill the asymmetrical gap below the corner descending ridge, is called corner gap filler *sumimendo gawara 隅面戸瓦. The latter filler tile and those used below the kudarimune are sometimes called katsuo mendo 堅魚面戸 or katsuo mendogawara 堅魚面戸瓦 (bonito filler tile).
