LP Gas Day

What Is LP Gas Day?

October 10th is "LP Gas Day" in Japan. The date commemorates the opening ceremony of the 1964 Tokyo Olympics on October 10, when the Olympic cauldron at the National Stadium was lit using LP gas, combined with a wordplay likening "10, 10" to the sizzling sound of cooking with gas. It was established by the Japan LP Gas Association.

A Familiar Energy Source That Supports Daily Life

LP gas (liquefied petroleum gas) is widely used in homes and restaurants across Japan, especially in areas where city gas service doesn't reach.

• Origin: combines the historic lighting of the 1964 Tokyo Olympic flame with LP gas and a wordplay on the sound of cooking
• Purpose: to spread awareness of the safe use of LP gas and its role as an energy source supporting daily life
• A key feature: supplied via individual gas cylinders, LP gas is considered relatively quick to recover after disasters
• Same date, related day: because of the same Olympic flame, October 10 is also "LPG Vehicle Day," established by the Japan LP Gas Association and others

The Advantage of Decentralized Energy During Disasters

Because LP gas is supplied to individual homes and facilities through cylinders, it's considered less vulnerable to large-scale infrastructure damage, drawing attention as a reliable energy source during disasters.

Tips for Marking This Day

• Check the safety inspection status of your home's gas equipment
• Learn about the differences between LP gas and city gas
• Talk with family about securing energy sources during a disaster
• Enjoy a meal cooked using LP gas

A Blue Flame Quietly Supports Everyday Life

The gas flame we rarely think about is actually a vital energy source supporting our tables and daily lives. October 10th is a day to give thanks for its quiet presence.
