Very often neglected (because duh, aren’t ventilation options only supposed to be just ON and OFF?), the Japanese apartment bathroom fan is not only good for drying the floor after a shower but for a lot of other things as well – including drying your laundry! In this article, I’ll be using the Dry Fan 24 that we have at home as an example. As always, the unit you have at home might look different, with more or fewer buttons or features. However, this guide should at least get you started on taking advantage of this tiny technological marvel.

Main Functions of the Japanese Apartment Bathroom Fan

This ventilation fan has four main functions represented by the four buttons on the bottom part of the panel.

乾燥 (Kansou) – Drying Clothes

For a lot of foreigners who are new in Japan, this is a new and very interesting function. The 乾燥 (kansou) button allows you to dry clothes inside the bathroom! This is especially useful during Japan’s notorious rainy season or in the cold winter months when drying clothes outside is not an option. Instead of relying on external weather conditions, you can use your Japanese apartment bathroom fan to ensure your laundry is dried efficiently and conveniently.

涼風 (Ryoufuu) – Cooling Fan

During the hot and humid summer months, the 涼風 (ryoufuu) button turns on the cooling fan. This function helps to circulate cool air throughout the bathroom, making it a comfortable retreat from the sweltering heat. It’s a simple yet effective way to maintain a pleasant atmosphere in your bathroom, ensuring that it stays cool and fresh.

暖房 (Danbou) – Heating

When the temperatures drop, the 暖房 (danbou) button turns on the heater, providing warmth to your bathroom. This feature is especially useful in winter, ensuring that your bathroom remains cozy and comfortable. Whether you’re taking a shower or getting ready in the morning, this function helps you stay warm and toasty, making your bathroom experience much more enjoyable.

標準換気 (Hyoujun Kanki) & ブロー換気 (Blow Kanki) – Ventilation Modes

The ventilation feature of the Japanese bathroom fan includes two modes: 標準換気 (hyoujun kanki) for standard ventilation and ブロー換気 (blow kanki) for a more thorough drying. The standard mode is perfect for regular post-shower ventilation, while the blow mode is ideal for when you need to completely dry out the bathroom. These modes help maintain a fresh and clean bathroom environment by preventing mold and mildew buildup.

Additional Buttons and Their Functions

Besides the main functions, the Japanese bathroom fan is equipped with several other buttons that enhance its usability and convenience.

タイマー切替 (Taimaa Kirikae) – Timer Settings

The タイマー切替 (taimaa kirikae) button, along with the arrow buttons, allows you to set the timer for the fan’s various functions. You can schedule the fan to operate at specific times, making it easier to manage your bathroom’s environment without manual intervention. This is particularly handy for ensuring your bathroom is always ready when you need it.

24時間換気 (24 Jikan Kanki) – Continuous Ventilation

Since a lot of apartment bathrooms in Japan don’t have windows to let air in, the 24時間換気 (24 jikan kanki) function ensures continuous ventilation, running the fan 24/7 to keep the air fresh. If you need to pause this function, for instance, when cleaning the filter, you can do so with a simple press of this button. It’s a convenient way to maintain air quality without having to constantly monitor the fan.

停止 (Teishi) – Stop Function

The 停止 (teishi) button is straightforward; it stops the current function in use. This is handy when you need to quickly turn off the fan or switch between different modes. Whether you’re adjusting settings or just need to stop the fan momentarily, this button provides a quick and easy solution.

フィルターリセット (Filter Reset) – Filter Maintenance

After cleaning the fan’s filter, you can reset the filter status by holding down the フィルターリセット (filter reset) button for about three seconds. This ensures the fan operates efficiently and reminds you to maintain the filter regularly. Proper filter maintenance is crucial for the longevity and effectiveness of your Japanese bathroom fan.

時計/セット (Tokei/Set) – Time Setting

To adjust the time displayed on the control panel, use the 時計/セット (tokei/set) button along with the up and down arrows. Keeping the correct time is essential for accurately scheduling the fan’s operations. This feature allows you to synchronize the fan’s functions with your daily routine, ensuring optimal performance and convenience.

Understanding the Indicator Lights

The Japanese bathroom fan features several indicator lights that provide additional information about its status and operations.

午前 (Gozen) and 午後 (Gogo) – AM/PM Indicators

The 午前 (gozen) and 午後 (gogo) lights indicate whether the displayed time is in the morning (AM) or afternoon/evening (PM). This helps in setting and reading the time accurately, ensuring that your scheduled functions are correctly timed.

お手入れ (Oteire) – Filter Maintenance Alert

The お手入れ (oteire) light signals when the filter needs cleaning. Regular maintenance ensures the fan functions optimally and extends its lifespan. Keeping an eye on this indicator helps you maintain the fan’s efficiency and effectiveness.

現代時刻 (Gendai Jikoku) – Current Time Display

The 現代時刻 (gendai jikoku) light shows that the control panel is displaying the current time. This is useful for verifying and adjusting scheduled operations. It ensures that the fan’s functions are synchronized with your daily schedule.

入時刻 (Iri Jikoku) – Scheduled Function Time

The 入時刻 (iri jikoku) light illuminates when a function is scheduled to run at a specific time. You can adjust the scheduled time using the arrow buttons. This feature allows you to plan ahead and ensure your bathroom environment is always to your liking.

切残時間 (Kiri Zan Jikan) – Remaining Time Display

The 切残時間 (kiri zan jikan) light indicates the remaining time before the current function ends. This feature helps you keep track of the fan’s operations and plan accordingly. It’s a handy way to ensure that the fan’s functions align with your needs.

Making the Most of Your Japanese Apartment Bathroom Fan

The Japanese apartment bathroom fan is an essential tool in maintaining a comfortable and functional bathroom environment. Its versatile functions, from drying clothes to providing continuous ventilation, make it an invaluable addition to any home.
