Gunkanjima: A “Battleship” of Industrial History in Nagasaki
With its rich nature and history, Nagasaki Prefecture offers many fascinating places to visit. One unique place in Nagasaki I recommend visiting is Hashima Island, commonly known as Gunkanjima (“Battleship Island”) due to its shape.
I first became interested in Gunkanjima when I was a university student, and I gave a presentation about the island for my Japanese class. Gunkanjima is small―only 6.3 hectares in area―but at one time it had a population of over 5,000 people. This means that Gunkanjima had the highest population density in the world! Most of these people worked in the coal mines below the island, or they were family members of the workers. In addition to housing, the tiny island featured shops, schools, hospitals, a shrine, and even a movie theater. An entire community of people lived, worked, and went to school on the island.
Starting in the late 1800s, Gunkanjima was inhabited for several decades. However, the mine stopped producing coal, and it was closed in 1974. Because the mine closed, all of the remaining workers had to leave the island to find jobs elsewhere. Then, the island became empty. The buildings on Gunkanjima remained and gradually became ruins.

島に残る建物群から、かつての暮らしの気配を感じることができます。
The island was closed to the public until 2009, when boat tours to the island began. When you go on a tour, you may not be able to set foot on the island. This is because the boat may have trouble docking due to rough seas. So, if you get to land, you’re lucky! I went on a tour, and I was fortunate to be able to land. The tour company I used even gave everyone a certificate commemorating our successful landing.

天候や海の状況によっては上陸できないことも。上陸できたら、とても幸運です。
Most of the island was still closed, and I was limited to a small walking area on one side of the island. But I was still able to see many of the decaying structures. I imagined how they looked decades ago when they were full of life. The contrast between past and present made me feel sad. Thanks to interest from the public, however, Gunkanjima has a hopeful future. Gunkanjima became a UNESCO World Heritage Site in 2015 as part of the Sites of Japan’s Meiji Industrial Revolution. Also, a research base was recently built on the island. It is the first new building on Gunkanjima in 56 years! This facility is dedicated to studying and preserving the island’s structures. I hope to visit again someday, and I encourage everyone to go see Gunkanjima for yourself.
ミニ解説+クイズ by 高橋美由紀(愛知教育大学名誉教授)
今回の英文では、長崎の軍艦島が紹介され、かつてのにぎわいと現在の静かな姿が対比されながら、その独特の魅力が語られています。筆者は、島が世界遺産に登録されたことや、保存のための研究施設が建てられたことに触れ、過去の姿に思いをはせつつも、未来への希望を感じています。この「過去と現在のコントラスト」と「未来への期待」が、筆者が軍艦島に強く惹かれている理由だと読み取れます。こうした外国人の視点から、日本の産業の歩みを見つめ直すことは、異文化理解だけでなく、自国の歴史や文化への新たな気づきにつながります。生徒たちが英語を通して日本を再発見する貴重な学びとなっています。
