What it is
The Good Luck Flag serves as a personal talisman for Japanese soldiers. It consists of the national banner covered in handwritten notes from relatives and friends. The text usually radiates outward from the central red circle, mimicking sunlight. This visual arrangement reinforces the connection between the bearer and their home community. The object acts as a physical reminder of collective hopes for survival and success during dangerous missions.
Where it comes from
The practice likely began during the First Sino-Japanese War around 1894. Signed flags became standard possessions alongside other protective items like the thousand stitch belt. While rare before 1931, the custom expanded significantly during the Second Sino-Japanese War and World War II. The tradition draws upon older feudal warrior codes that emphasized duty and honor above personal safety.
How it is done
Community members gather to sign the banner using ink and brushes. Names and short wishes are written vertically around the red center. Messages often include phrases wishing for long-lasting military fortune. If space runs out, writers fill the white background completely. Some banners feature small drawings of tigers or caricatures to add personality to the gift.
Tools and materials
The primary tool is the national flag itself, typically made of silk or synthetic fabric. Writers use black ink and calligraphy brushes to apply the text. The layout follows a specific pattern, with signatures fanning out from the middle. Additional decorations might include images of animals or bold slogans placed along the edges.

What it is for
The flag provides emotional strength to the recipient far from home. It symbolizes the combined prayers of the community for the soldier's safe return. In some cases, it also serves as a funeral substitute when a soldier leaves behind hair or nails for burial rites. The object reminds the bearer of their obligations to country and family.
Who does it
Ordinary citizens create these items for departing servicemen. Neighbors, coworkers, and family members contribute their signatures. The process requires no special training, only a desire to offer support. Historically, this was a domestic activity performed by households preparing for war.
Peoples and places
The tradition originated in Japan and spread through its military forces. During World War II, many flags ended up in the hands of American soldiers as battlefield souvenirs. These items were sometimes traded or kept as trophies. Today, the practice remains active within Japan for various civilian send-offs.

What people believe
The custom reflects the cultural value of self-sacrifice prevalent during wartime. Soldiers were expected to view death in service as an honorable outcome. The flag represents a bond that transcends physical distance, linking the warrior to his ancestors and descendants through shared ritual.
When it is done
Flags are traditionally given before induction into the armed forces or prior to overseas deployment. Modern usage extends to graduation ceremonies, retirement parties, and farewell events for colleagues. The practice also appears after natural disasters to show solidarity with affected communities.
How scholars and sceptics see it
Historians note the transition of feudal warrior ethics into twentieth-century military culture. Anthropologists study the object as a symbol of communal identity and pressure. Accounts from veterans describe the complex emotions surrounding the acquisition and retention of these banners.
Cautions and what is closed
The practice is tied to a period of intense militarism and state-sponsored sacrifice. Many surviving examples are held abroad as contested artifacts. The OBON Society works to identify owners and facilitate the return of these items to Japan, viewing repatriation as a gesture of reconciliation.
Compare and confuse
The Good Luck Flag shares similarities with the senninbari, or thousand stitch belt. Both objects serve as protective amulets created by community members. Unlike the headband worn for focus, the flag is a larger textile meant for display or storage.
