Moon Landing Day

What Is Moon Landing Day?

Every July 20th is "Moon Landing Day" (月面着陸の日, Getsumen Chakuriku no Hi) in Japan. On July 20, 1969 (July 21st in Japan Standard Time), American astronauts Neil Armstrong (ニール・アームストロング) and Buzz Aldrin (バズ・オルドリン) of the Apollo 11 mission became the first humans in history to land on and walk on the surface of the Moon. Armstrong's famous words — "That's one small step for [a] man, one giant leap for mankind" — were broadcast to the world, including Japan, where the event was followed with enormous interest and excitement.

Apollo 11 and the World

The Apollo 11 Moon landing was one of the defining moments of the 20th century — the culmination of the Space Race between the United States and the Soviet Union, an extraordinary demonstration of human technological achievement, and a moment of shared global wonder. In Japan, the event was broadcast live (in the early morning hours of July 21st Japan time) and attracted enormous television audiences. Japan was in its own rapid development phase — just five years after the 1964 Tokyo Olympics had announced Japan's postwar recovery — and the Moon landing captured the country's technological optimism.

Japan's Relationship with the Moon

The Moon holds special significance in Japanese culture and literature — from the "Moon-Viewing" tradition (お月見, tsukimi) celebrated on the harvest moon to the classic tale of Princess Kaguya (かぐや姫), who came from the Moon and returned to it, to countless poems in the classical tradition that use the moon as an image of impermanence, beauty, and longing. The Moon landing — placing human footprints on a surface that had been purely poetic for millennia — created a complex cultural resonance in Japan.

Japan's Lunar Program

Japan has developed its own lunar exploration program through JAXA. The SELENE (Kaguya, かぐや) lunar orbiter (2007-2009) mapped the Moon's surface in unprecedented detail. The SLIM (Smart Lander for Investigating Moon) mission achieved Japan's first successful lunar landing in January 2024 — making Japan only the fifth country to land a spacecraft on the Moon. Japan is a partner in NASA's Artemis program for crewed lunar return.

Fun Facts

• Tsukimi: Japan's Moon-viewing tradition (お月見, tsukimi) — held on the full moon of the eighth month of the traditional lunar calendar, typically falling in September — involves offering rice dumplings (月見団子, tsukimi dango) and autumn grasses to the Moon while viewing it. The tradition connects ancient agricultural gratitude for the harvest to the poetic appreciation of the Moon's beauty.
• "One giant leap": Neil Armstrong's famous words were translated into Japanese as "これは一人の人間にとっては小さな一歩だが、人類にとっては大きな飛躍だ" — a translation that appears in Japanese textbooks as an example of a historic statement delivered in English that transcended national boundaries.
