Trivia and General Knowledge Quiz on Money-Saving Tips Useful in Daily Life (1–10)
Which of the following reasons explains how using the hometown tax (Furusato Nozei) can lead to savings?
- Because you get cash back equal to the amount you donated
- Because deductions reduce the amount of tax you would otherwise have to pay.
- Because you can donate to any municipality.

Because deductions reduce the amount of tax you would otherwise have to pay.
When it comes to the hometown tax program, many people think of it as a way to get local specialties at a bargain, but it is essentially a system related to local taxation. By donating to a municipality you want to support, money flows to that region as a donation, and part of your resident tax and income tax is deducted by the amount you donate. Since you also receive a return gift from the municipality, it allows you to save money advantageously while effectively reducing your out-of-pocket cost.
When using the air conditioner, which of the following is most effective for saving on electricity costs?
- turn it on and off frequently
- Clean the filter regularly
- Always operate in strong-wind mode
See the answer
Clean the filter regularly
If an air conditioner’s filter is dirty with dust and the like, airflow worsens and heating/cooling efficiency drops significantly. As a result, power consumption increases and your electricity bill goes up. By cleaning the filter regularly, the unit can operate more efficiently, preventing unnecessary power use and yielding substantial savings.
Which of the following heating appliances has the lowest electricity cost per hour?
- air conditioner
- kotatsu
- electric heater
See the answer
kotatsu
A kotatsu is characterized by its ability to efficiently warm only a small area, making its hourly electricity cost cheaper than other heating appliances. Generally, air conditioners and electric heaters are thought to consume more power because they heat an entire room. However, actual power consumption and electricity costs can vary depending on factors such as the usage environment, temperature settings, and room size, so that’s an important point to keep in mind.
Which of the following is an effective way to reduce communication expenses?
- Sign up for an unlimited plan
- Switch to a budget SIM
- I’ll upgrade when a new model comes out.
See the answer
Switch to a budget SIM
To keep communication costs down, it’s important to choose a plan that matches your usage. By switching to a budget SIM, you can often significantly reduce your monthly base fee compared to major carriers, helping cut unnecessary expenses. Explore the various plans available, including budget options, to find the one that suits you best.
If you drink tea regularly, which method saves the most money?
- Buy bottled tea in bulk
- Buy tea at a convenience store
- Brew it yourself from loose tea leaves or tea bags.
See the answer
Brew it yourself from loose tea leaves or tea bags.
Brewing tea at home from loose leaves or tea bags can keep the cost per cup low. It’s more economical in the long run than buying bottled tea or getting it at convenience stores, and a big advantage is that you can adjust the flavor and strength to your liking.
Which of the following expenses would lead to the greatest savings if reviewed?
- food expenses
- communication expenses
- Leisure expenses
See the answer
communication expenses
The key point with fixed costs like communication expenses is that by reviewing them once and switching to an appropriate plan, or canceling unnecessary options and services, you can achieve ongoing monthly savings. Of course, it’s important to review variable expenses like food and leisure as well, but cutting fixed costs has a greater long-term impact. In particular, smartphone plans and internet connections can easily lead to waste if they don’t match your usage, so it’s advisable to review them regularly.
Which household appliances incur electricity costs due to standby power even when they are turned off?
- television
- refrigerator
- microwave oven
See the answer
television
Even when turned off, a TV consumes a small amount of power—so-called standby power—so it can be turned on via a remote control or similar device. Because electricity is used for remote control operation and timer functions, you will incur a small electricity cost even when the power is off unless you unplug it completely.
