A Honolulu institution is throwing open its factory doors for a free public party, good news for local families and fans of its soda crackers.

• Diamond Bakery is marking 105 years with a free community celebration at its Kalihi factory today.
• The event runs through the afternoon at the factory outlet on Mokauea Street, with free food, giveaways, and a rare guided factory tour.
• Mayor Rick Blangiardi and Governor Josh Green are both expected to recognize the milestone.
• The company was started by three Japanese immigrants in 1921 and its Hawaiian soda crackers have been a pantry staple for generations.

Outlook: The celebration wraps up this afternoon, with the factory outlet returning to normal business after.
