The image is a photograph of a sign in Japanese that explains the different types of mines that are born from the combination of mine-laying and ignition methods. The sign is displayed on a dark blue background with white text.

On the left side of the sign, there is a text in both English and Japanese that translates to "Minesweeper" in English. Below the text, there are two bullet points that explain the different methods of mining. The first bullet point explains that floating in the sea or lying on the sea floor, mines wait silently for their prey. The second bullet point shows a map of the mine, showing the different levels of mining and how they interact with each other. The map is divided into different sections, each with a different color and a different type of mine. The colors range from light brown to dark brown, with some areas being darker and others being lighter. The text is written in both Japanese and English.
