妻の(つまの)宮木は(みやぎは)何年も(なんねんも)前に(まえに)すでに亡くなって(なくなって)おり、約束を(やくそくを)果たす(はたす)ために幽霊となって(ゆうれいとなって)待っていたということ

However, when Katsushiro woke up the next morning, Miyagi's body, which should have been warm, had vanished. There was only a crumbling old grave and cold autumn leaves left. In truth, Miyagi had died years ago while waiting for her husband, and had waited as a ghost to fulfill her final promise to him. Katsushiro deeply regretted his long absence and collapsed crying in front of the grave. It is an immortal masterpiece of Japanese supernatural literature.
