Did You Know Summer Starts in March in Japan? (The “Umi-biraki” Secret)

Freezing Tokyo
In March, most of Japan is still shivering. People in Tokyo are wearing heavy winter coats, waiting for the cherry blossoms to finally bloom at the end of the month. But did you know that in another part of Japan, people are already swimming in the ocean?

The Long Archipelago
Japan is a surprisingly long country, stretching over 3,000 kilometers from north to south. While the northern island of Hokkaido is still buried in thick snow, the southern islands are already experiencing summer weather.

The “Umi-biraki” Ritual
In these southern tropical regions, March marks the official “Umi-biraki” (Beach Opening) season! It is not just about putting up a volleyball net. Umi-biraki is a traditional Shinto event. A local priest stands on the white sand, waves a sacred wand, and prays to the ocean gods for the safety of swimmers and a prosperous tourist season.

The First Swim
As soon as the priest finishes the prayer, local children and tourists cheer and run into the crystal-clear water, officially kicking off the swimming season months before the rest of the country.

A Tropical Escape
If you visit Japan in March and get tired of the cold city weather, just hop on a domestic flight down south. Within a few hours, you can trade your winter coat for a swimsuit and enjoy an early summer on a stunning white sand beach!
