Historical Origins & Legal Milestones
On May 3rd 1947, the post‑war Nihonkoku Kenpou (日本国憲法) replaced the Meiji Constitution (明治憲法), embedding three core principles—the sovereignty of the people (国民主権), pacifism (平和主義), and respect for fundamental human rights (基本的人権の尊重). Kenpou Kinenbi (憲法記念日) was established to commemorate the charter’s enactment, inviting citizens to reflect on democratic ideals and Japan’s resolve to renounce war.

Constitution Memorial Day Inside Golden Week
Kenpou Kinenbi sits at the heart of Golden Week (GW)—a string of national holidays that triggers one of the country’s biggest travel booms. For many Japanese, constitutional contemplation coexists with Shinkansen tickets and ski‑resort packages.
Some people join events to learn about the constitution and reflect on peace. However, most people spend the day as part of Golden Week—traveling, relaxing, or enjoying time with family and friends.
Travel Tip
If you plan to join the crowds, reserve rail seats one month in advance and budget extra time for highway congestion.

Conclusion
Kenpou Kinenbi is more than a day off; it is a living reminder of Japan’s constitutional journey and a linchpin of Golden Week culture. Whether you’re queuing for a Diet tour or soaking in a volcanic onsen, spare a thought on May 3rd for the document that reshaped modern Japan—and enjoy the uniquely Japanese blend of civic reflection and leisure.
