Teshikaga is the central gateway to the Akan-Mashu National Park, a region where the earth’s raw energy is visible at every turn. From the billowing sulfur vents of Mt. Iou (Atosanupuri) to the crystal-clear depths of Lake Mashu and Lake Kussharo, Teshikaga offers an unparalleled nature experience. With a Teshikaga private car tour, you can easily navigate between these geological wonders and relax in the famous “acidic” healing waters of Kawayu Onsen without the hassle of navigating remote mountain passes on your own.

  1. Efficient “Triple-Lake” Routing: Teshikaga is the hub for Lake Mashu, Lake Kussharo, and Mt. Iou. A private car is the most efficient way to see all three iconic landmarks in a single day—a feat difficult to achieve via local public transport.
  2. Direct Access to Hidden Hot Springs: Beyond the main towns, Teshikaga is dotted with hidden open-air baths and foot spas. Our private car service takes you directly to these serene spots for a relaxing break between sightseeing.
  3. Hassle-Free Airport & Station Links: We provide seamless transfers from Kushiro Airport or JR Mashu Station to your Kawayu Onsen ryokan, ensuring your luggage is handled safely while you enjoy the scenery.

SummerJul – Aug14°C ~ 22°CPerfect Mountain Climate. Ideal for hiking and scenic drives. Wear light clothes, but keep a sweater for the cool evening mountain air.
AutumnSep – Oct4°C ~ 15°CVibrant Fall Colors. The area around Mt. Iou turns stunning red. A warm coat and scarf are recommended for outdoor exploration in October.
WinterNov – Apr-13°C ~ -2°CThe Frozen Frontier. Teshikaga is one of Hokkaido’s coldest areas. High-quality heavy down coats and thermal base layers are mandatory.
  • Mt. Iou (Sulfur Mountain) Etiquette:
    Mt. Iou is an active volcanic site with strong sulfur steam. The ground can be uneven and dusty. We recommend wearing comfortable sneakers and being mindful that the sulfur scent can linger on delicate fabrics.
  • The Kawayu Onsen “Acidic” Waters:
    Kawayu Onsen is famous for its highly acidic water. It is excellent for skin health but can damage jewelry. Remember to remove any silver or metal accessories before soaking in the local hot springs.
  • Star Gazing (Mashu Starry Sky):
    Teshikaga is known for having some of the clearest night skies in Japan. If you plan an evening tour to Lake Mashu for stargazing, even in summer, the temperature drops significantly. Your private car will provide a warm sanctuary between telescope views.
