【WORLD HERTAGE SITE】Aiura Station is about 30 minutes from Sasebo Station by Matsuura Railway. After getting off at Aiura Station, it takes about 50 minutes by ferry from Aiura Pier to Kuroshima Island. When I visited Kuroshima Cathedral on a marbling winter morning, an elderly man kindly guided me inside the Cathedral. Kuroshima is the largest island in Kujukushima Islands of scenic beauty, floating on 10 km west of Sasebo mainland. Many of the hidden Christians who had escaped from persecution lived there since the Edo era, and the current cathedral was built under the guidance of Father Marman and completed in 1902.
