🔗 Overview of amenities provided（Select the type of lodging you will be staying at)
* Please thoroughly wash, dry, and put away dining and cookware after use. We ask for your cooperation in ensuring that the next guests can use them comfortably.
🧖♀️ Relax in the sauna with fresh outdoor air
Our lodgings with private saunas allow guests to fully relax while enjoying an open-air experience surrounded by the soothing sounds and scents of nature.
*Please bring your own swimwear when using the sauna at SANU 2nd Home. For an even more comfortable and enjoyable experience, we recommend bringing a sauna hat or poncho as well.
*Sauna facilities vary by location. For details, please refer to the Equipment Operation Manual.
-
About 30–45 minutes before using the sauna (or around 1 hour in winter), turn on the heater to warm up the sauna and fill the cold bath with water.
Before entering the sauna, rinse your body using the shower or cold bath water, then dry off. Place a sauna mat on the bench and take a seat.
If you're using a barrel sauna, gently pour water over the sauna stones to enjoy a steam session (löyly).
After your sauna session, rinse off any sweat and relax in the cold bath or in the outdoor “totonoi” (cool-down) chair area.
-
Löyly bucket and ladle, wash basin, leaf skimmer for the cold bath, and two pairs of outdoor sandals.
🔥 Gather around the bonfire (until 10:00 p.m.）
Spend a relaxing moment gathered around the fire, simply watching the flames. Some cabins are equipped with a fire pit and firewood (available for purchase). For added comfort, we recommend bringing your own outdoor chairs, tables, or other camping gear.
-
Place 2–3 fire starters in the center of the fire pit.
Arrange kindling (small firewood) over the fire starters, leaving some space between pieces to allow airflow. Once set, light the fire starters with a lighter.
Once the kindling is burning steadily, add larger logs to build the fire. Wait until the fire settles before starting any cooking.
Once the fire is stable, it will continue to grow naturally. For cooking, it's best to use the glowing embers (hot coals).
-
About two hours before you plan to finish, begin reducing the amount of firewood you add to the fire.
Let the remaining firewood burn completely and confirm by sight that the fire is fully extinguished. Then, place the lid on the fire pit. If any unburned wood remains, use tongs to remove it and douse it thoroughly with water on the gravel until it is fully extinguished.
Use the bucket and shovel located next to the ash disposal area to collect the ashes and any remaining unburned wood. Dispose of them in the ash bin. Please return the bucket and shovel to their original place, and bring any unused firewood or equipment taken from the facility back indoors.
Please return the bucket and shovel to their original place, and bring any unused firewood or equipment taken from the facility back indoors.

☕️ Morning coffee on the terrace
In your room, you’ll find carefully selected coffee beans (available for purchase) from SANU’s curated collection, including ONIBUS COFFEE and Overview Coffee, along with filters and grinders.
ONIBUS COFFEE is a famous coffee brand that is also known for giving back to the community. Here, we share four steps from founder Atsushi Sakao on how to brew delicious coffee the ONIBUS way.
How to Brew Delicious Coffee
Measure your coffee beans and water. The ideal coffee-to-water ratio is 1:17. At ONIBUS, they use 13g of beans to 225ml of water per cup.
Adjust the grind size and grind the beans. Aim for a grind that’s neither too coarse nor too fine—uniform particle size is key.
Heat water to 93–95°C (199–203°F). Before placing the coffee grounds, rinse the paper filter with hot water to remove any papery taste.
Brew the coffee. Pour the hot water in a circular motion—first from the center outward, then from the outside inward—to evenly saturate the grounds. Stir gently once with a spoon to mix the grounds evenly. Continue pouring slowly and complete the extraction over about 3 minutes.
