The Japan Maritime Self-Defense Force Fleet Air Wing 31 and Marine Corps Air Station Iwakuni are pleased to announce that our combined open-house, Friendship Day, will take place on Sunday, May 3, 2026. This Friendship Day will be the 47th iteration and offers an exciting, fun-filled event, which will consist of static displays, aerial performances, and numerous vendors.

As members of the greater Iwakuni community, it is our pleasure to open our gates, in concert with Fleet Air Wing 31, to the people of Japan to share our two cultures, thank the citizens for the continued support of the air station, and demonstrate the strength of the U.S. – Japan Alliance. Friendship Day promises to be an entertaining event for all involved.

Planning and coordination for Friendship Day is ongoing, and additional details will be made available as they are solidified. Until then, we request that the media withhold all queries seeking additional information about the event.
