Magic Mirror – Reflections of Hidden Devotion
A magic mirror is a remarkable Japanese craftwork that reveals hidden images when light is cast upon its surface. Though it looks like an ordinary mirror, patterns or sacred figures engraved on the reverse side mysteriously appear in the reflection.
During the Edo period, under the ban on Christianity, Kakure Kirishitan (Hidden Christians) are said to have used mirrors engraved with the image of Christ. By shining light onto the mirror, the figure of Christ would be projected, allowing them to pray in secret. To avoid suspicion, the reverse was often covered with a lid featuring harmless decorative patterns.
Today, magic mirrors are valued not only as rare religious artifacts, but also as exceptional examples of Japan’s advanced casting techniques and spiritual culture. Experience the mysterious beauty of light and shadow captured within this extraordinary mirror.
