Go Day (Igo no Hi)

What is Go Day?

January 5th is "Go Day" (Igo no Hi) in Japan, proposed by the Nihon Ki-in (Japan Go Association) based on a wordplay where "i" (1) and "go" (5) combine to sound like "igo" (the board game Go). The day aims to promote the game of Go and introduce more people to its appeal, and it is a meaningful milestone for enthusiasts who enjoy the quiet battle of wits at the start of a new year. January 15th, meanwhile, is known as "Ii Go no Hi" (Good Go Day).

A game with a long history

Go has a long history, and its basic rules have been handed down largely unchanged.

• Origins in China: Go is believed to have originated in ancient China and has been played across East Asia for more than 2,000 years. It reached Japan early on: Go boards and stones are preserved in the Shōsōin, the treasure house of Nara-period (8th-century) artifacts, and Go scenes appear in Heian-period classics such as "The Pillow Book" and "The Tale of Genji."
• Warlords and the shogunate: Go spread as a pastime of samurai warlords in the Warring States period. In the Edo period the shogunate supported professional players, giving rise to Go houses such as the Hon'inbō house and the top official post of "Go-dokoro."

Go and modern technology

Go also marked a major turning point in the history of artificial intelligence.

• The shock of AlphaGo: In 2016, the AI "AlphaGo" defeated one of the world's top Go players, making headlines around the world. Winning at Go—a game with more possible board positions than there are atoms in the universe—was hailed as a historic achievement for AI research.
• Coexisting with AI: Today's professional players use AI to analyze their games and study new strategies. AI has also prompted players to rethink moves long considered standard.

Interesting facts about Go

• Go words in everyday Japanese: Many everyday Japanese expressions come from Go, including "dame" (no good), "fuseki" (groundwork), "sute-ishi" (a sacrificed stone), "jōseki" (standard practice), and "ichimoku oku" (to acknowledge someone's superiority).
• 361 points: A 19x19 board has 361 intersections. Excluding the center point ("tengen") leaves 360, which some have likened to the days of a year.
• The name "shudan" (hand conversation): Because players "talk" through the stones without exchanging words, Go has long been known by the elegant name "shudan," meaning "conversation through the hands."
• The Nihon Ki-in: Founded in 1924, the Nihon Ki-in has about 300 professional players and operates Go centers overseas.
• The influence of "Hikaru no Go": The hit manga "Hikaru no Go," serialized from the late 1990s to the early 2000s, sparked a Go boom among children in Japan and drew attention overseas as well.

Enjoying the infinite creativity found in quiet contemplation

Go Day is a day to reflect on the endless stories woven by black and white stones, and to trust your own intuition and logic as you search for your next move. The act of placing your intentions on a vast board is much like drawing the blank map of your own life. On January 5th, rather than fixating only on winning or losing, why not appreciate the beauty of the "process"—placing each stone thoughtfully, one at a time? Just as two opposing colors create harmony on the board, Go is full of wisdom about respecting differing opinions and building a harmonious future.

Ideas for enjoying Go Day

• Bring out your Go board after a long while and replay a famous historical match, feeling the rhythm of past masters' thinking through your fingertips.
• Use a Go app or online platform to enjoy "hand conversations" with players from around the world, broadening your way of thinking.
• Teach the basic rule of "surround and capture" to a friend or family member who's never played, sparking an intellectual conversation.
• To mark January 5th (Go Day), if you're facing a decision, try thinking with a "Go player's perspective"—looking a step ahead and viewing the whole picture.

The ripples from a single stone shape a brilliant outcome

January 5th is a day when your small, unassuming step becomes an important move that shapes your future success. Just as a game of Go begins with a single stone, your dreams too take shape through the steady accumulation of daily efforts. A broad perspective and the courage to embrace change without fear will lead you to a satisfaction deeper than mere victory. May today be the first brilliant move of an intellectually stimulating, sharp year ahead.
