A pattern of parallel lines decorating the pendant *gatō 瓦当 of a broad, concave eave-end tile *nokihiragawara 軒平瓦. These lines follow the deep bow-like curvature of the tile and extend all the way to ends. It is believed that the pattern was made by pressing a mold into the tile's wet clay during the production stage. If nokihiragawara have a border created by parallel lines that do not reach the edges of each end, they are called jūkakumon 重廓文. Examples have been found at the sites of Yamadadera 山田寺 (6th century) in Nara, that have three parallel lines sanjūkonmon 三重弧文 and examples found at Kawaradera 川原寺 (6th century) in Nara, have four parallel lines yonjūkomon 四重弧文. A set consisting of a pendant tile for semi-cylindrical, convex eave-end tile *nokimarugawara 軒丸瓦 and a broad, concave eave-end pendant tile nokihiragawara was unearthed at the site of Bingo Kokubunji 備後国分寺 in Hiroshima Prefecture. Aside from these early examples the use of concentric circles on the pendants nokimarugawara and parallel lines on the pendants of nokihiragawara was especially popular in the Heian period.
