When is the main shrine at Ise rebuilt?

The main shrine at Ise, known as the Ise Jingu, is rebuilt every 20 years as part of a tradition that dates back over a millennium. This ritual, known as "Shikinen Sengu," involves constructing a new shrine adjacent to the old one, after which the old shrine is dismantled. The next rebuilding is scheduled for 2033, continuing this long-standing cultural practice. This cycle symbolizes renewal and the impermanence of life.
