To the joy of some, and perhaps the surprise of others, next Tuesday is a one-off national holiday.

While some may happily take the day off, it is also the day when dignitaries from across Japan and the world will gather in Tokyo to witness a once-in-a-generation event — the declaration of an emperor's enthronement.

With banquets, a parade and other examples of pomp and splendor also in the offing, the public will see plenty of imperial spectacles over the coming month.
