This Tree House Resort in Japan Features 360-Degree Jungle Views — Plus a Slide from the Sauna into the Genka River

As a child, Satoru Kikugawa was captivated by a book titled “I Want a Big Tree,” where the main character seeks a giant tree to build a tree house. This childhood story left a lasting impression on him, leading him to explore northern Okinawa years later for the largest tree he could find, ultimately discovering a magnificent Akagi in the untouched forests. Upon seeing it, he embraced the tree and thought, “This is the one!”

After beginning construction in 2014, that very tree has become home to the Spiral Tree House, one of two unique accommodations at his Treeful Tree House sustainable resort in Nago, Okinawa, which opened its doors in 2021.

Featuring a spiral staircase that ascends to the Spiral Tree House, this retreat seamlessly blends nature with comfort, offering panoramic views of the lush jungle on the Japanese island. Enjoy a cozy deck adorned with string lights and decorative pillows, along with amenities like two hammocks, two yoga mats, a mini fridge and freezer, a compost toilet, air conditioning, and a semi-double bed.

Perched in a nearby tree is the AeroHouse, a sustainable luxury rental crafted by architect Tadashi Murai and adorned by interior designer Yasuhiro Koichi. This spacious retreat features expansive open windows, a fully-equipped kitchen with a microwave, oven, fridge, and freezer, as well as a wine cellar, day bed, king-sized bed, shower, toilet, and even a washing machine.

A third tree house, named the Trophy Tree House, is currently under construction, featuring a Japanese tea room theme along with two futons, a flushable toilet, and a rooftop viewing area.

A standout feature of the property is the Indigo Sauna Tree House, designed for groups of up to six people for three-hour sessions. After warming up in the sauna with stunning floor-to-ceiling windows, guests can slide down directly into the Genka River below. This fun cycle can be repeated as often as desired, with relaxation and spa rooms available for added tranquility. Every wooden support in this tree house is coated with Okinawan indigo dye, and the slit-style structure, crafted from thin rods with gaps, allows natural sunlight to illuminate the space during the day.

Recent guests have praised the on-site dining options, which include a delightful fireside dinner on an open grill featuring dishes like Agu pork shabu-shabu and Okinawa soba noodles; Agu pork and Okinawa Motobu beef mixed sukiyaki; as well as seafood BBQ and Okinawan Jushi steamed rice.

At the heart of the resort lies its commitment to sustainability: the tree house is carbon-negative, operating entirely on renewable energy sourced from Okinawa Electric Power’s Uchina CO2 Free Menu, without the use of fossil fuels. Additionally, all structures are elevated to maximize natural sunlight and support the thriving ecosystem below.

The resort notes on its website, 'We view ourselves as renting the space on the tree,' highlighting their environmentally conscious approach to water, waste, and building materials.

Ultimately, Treeful Tree House aims to foster a deep connection between guests and the breathtaking natural surroundings. As the resort states, 'At Treeful, you can discover numerous ways to unwind in nature and escape the hectic pace of modern life.'
