It might sound warm at first, but 28°C is Japan's recommended energy-saving setting. It keeps your room comfortable while using less electricity.

Pro Tip : Skip the manual fan settings and use Auto Mode instead. Your AC knows how to cool your room more efficiently than constant high-speed blasting.

Think of your fan as your air conditioner's sidekick.

A fan uses only a fraction of the electricity, but it helps spread cool air around the room, making it feel cooler even when your AC isn't working overtime.

Less work for your AC = Less damage to your wallet.

Sunlight is free... but the extra electricity it causes isn't.

During the hottest hours:

• Close your curtains.

• Pull down the blinds.

• Use blackout curtains if you have them.

Your room stays cooler, and your AC won't have to fight the afternoon sun.

A dusty air filter is like trying to breathe through a face mask while running a marathon.

When the filter is clogged, your AC works harder—and uses more electricity.

Spend 10 minutes cleaning it every 2–4 weeks. Your future electric bill will thank you.

Believe it or not, many appliances keep sipping electricity even when they're turned off.

Common culprits include :

• TVs

• Rice cookers

• Microwaves

• Phone chargers

• Gaming consoles

Unplug them or switch off the power strip before heading to work.

Every little yen counts.

Summer isn't exactly asking for warm laundry.

Wash your clothes with cold water whenever possible. It saves electricity and helps protect your clothes.

And if the weather's nice? Let the sun do the drying—for free.

We've all stood in front of the fridge wondering what to eat...

Unfortunately, your refrigerator doesn't enjoy that game.

Every time the door stays open, warm air rushes in and the compressor works harder.

Quick mission :

• Know what you need.

• Grab it fast.

• Close the door.

Simple.

Cooking generates heat—and your AC has to work even harder to cool it down.

Try these energy-saving hacks:

• Cook several meals at once.

• Reheat with the microwave.

• Prepare meals during cooler hours.

Your future self (and your electric bill) will appreciate it.

Japan has many electricity providers, and newer plans may fit your lifestyle better.

If you've been with the same company for years, it might be time for a quick comparison.

A small monthly saving can turn into thousands of yen over a year.

Most Japanese electric companies offer apps or online portals where you can monitor your daily electricity usage.

It's like checking your bank balance—but for your power consumption.

Once you know what's using the most electricity, it's much easier to cut back.
