And so, the title composed of even-numbered Chinese characters, such as "義経" (Yoshitsune) and "四谷怪談" (Yotsuya Kaidan), was intentionally added odd-numbered Chinese characters, such as "千本櫻" (Senbonzakura) and "東海道"(Tokaido), so Gedai became long, as is exemplified by "義経千本櫻" (Yoshitsune Senbonzakura) and "東海道四谷怪談" (Tokaido Yotsuya Kaidan).
このため『義経』や『四谷怪談』のようにどうやっても割れてしまう字数には、あえて「千本櫻」や「東海道」などの奇数の字を付け足して『東海道四谷怪談』や『義経千本櫻』などいった長い外題とした。
