The site was an old machikoba in Kamata. [1]
The security camera had triggered. But the footage showed nothing.
The manufacturer that received the complaint assembled an investigation team immediately. They updated the software. They replaced the camera lens with a new one. They adjusted the sensor sensitivity downward in stages. Even so, at the same location and at the same time, the sensor kept triggering.
When they entered the third week, the team leader wrote out every candidate cause. The list had twenty-seven items. They worked through them one by one. When the twenty-seventh had been eliminated, nothing remained on the whiteboard.
At that point a young technician spoke up. “Could it be electromagnetic interference? There are high-voltage power lines nearby.” The team stirred with renewed energy. The following morning they contacted the power company, took measuring equipment, and headed to the site. The readings were normal. Everyone fell silent.
They had run out of options.
The person they ultimately turned to was someone no one had anticipated.
The client’s representative said, with a look of mild apology, “There is a rather unusual man who lives nearby.” The team leader could not think of a reason to refuse.
The next day, the man came. His appearance was entirely ordinary. He was not carrying anything in particular. He looked at the location of the camera installation for a moment, and then was silent for a while.
Then he took prayer beads in his hand and spoke. [2]
“I can see them. The former company president is coming in to work as a ghost.”
[1] Kamata is a district in Ōta Ward, Tokyo, historically associated with a dense concentration of machikoba (町工場): small, specialist manufacturing workshops producing precision parts, metal components, and industrial supplies for larger companies. The kind of cramped, independently run factory the word conjures is deeply embedded in the area’s identity, giving the setting a very specific industrial texture for Japanese readers.
[2] Juzu (数珠) are Buddhist prayer beads, a string of beads used in meditation and ritual practice across various Buddhist traditions in Japan. They are closely associated with priests and devout practitioners, and the act of taking them in hand before making a pronouncement signals to Japanese readers that this person is presenting themselves as a spiritual authority.

【1分小説】27のリスト
現場は蒲田の古い町工場だった。防犯カメラが反応した。しかし映像には何も映っていなかった。
クレームを受けたメーカーは、すぐに調査チームを組んだ。ソフトウェアを更新した。カメラのレンズを新品に交換した。センサーの検知感度を段階的に下げた。それでも同じ場所で、同じ時刻に、センサーが反応し続けた。
三週目に入ったとき、チームリーダーが原因候補をすべて書き出した。リストは二十七項目あった。順番に潰していった。二十七番目を潰し終えたとき、ホワイトボードには何も残っていなかった。
そのとき若い技術者が言った。「電磁波の干渉じゃないですか。近くに高圧線がありますよね」。チームは色めき立った。翌朝、電力会社に連絡を取り、測定器を持って現地に向かった。数値は正常だった。全員が黙った。
手が尽きた。
最終的に頼ったのは、誰も想定しない人物だった。
クライアントの担当者が、少し申し訳なさそうに言った。「近所に、ちょっと変わったおじさんがいるんですが」。チームリーダーは断る理由を思いつかなかった。
翌日、おじさんがやってきた。ごく普通の格好だった。特に何かを持っているわけでもなかった。カメラの設置場所を一目見て、しばらく黙っていた。
それから手に数珠を握って言った。
「私には見えます。先代の社長さんが、幽霊になって出勤しています」
