Matariki is the Māori New Year in New Zealand, based on the rising of the Matariki star cluster (Pleiades). It is a time of remembrance, celebration, and renewal, officially recognized as a public holiday since 2022.

Marine Day honors the ocean's importance to Japan as an island nation, recognizing its role in providing food, transportation and prosperity. The holiday encourages appreciation for the sea and maritime culture. Many people visit beaches, participate in ocean-related events, and enjoy fireworks or festivals celebrating Japan's close connection to the sea.
