This morning set out to explore Oku Nikko, the "hinterland of Nikko," an area of outstanding natural beauty in the mountainous north of Nikko and now a protected national park. Enjoy leisurely trekking in the Karikomi Lake area, famous for its natural sulfur hot springs. Monks have harnessed these waters for their healing properties since their discovery in 788 - and at your ryokan, in the Nikko Yumoto Onsen area, you can experience these waters for yourself! You'll also explore the surrounding marshlands and their wide array of bird life.

Travel to Yamagata and hike to Yamadera, the "mountain temple" known as Risshaku-ji. This Tendai sect of Mahayana Buddhism temple is perched atop the mountainside with 1,000 steps leading to it. The upper temple houses a sacred flame that has been burning since the temple was founded in 860! A viewing platform situated slightly farther up the mountain offers impressive views of the neighboring peaks and the valley below. Descend and board the train to scenic Ginzan Onsen, a small hot springs town known for traditional wooden onsen lining the riverfront. Please see luggage FAQ for more details on this day.

After breakfast and perhaps another quick soak in the hot spring, we take a bus to our nearest railway station and catch the shinkansen (bullet train) north, following the Japan Sea's picturesque coastline to Dewa Sanzan - the three sacred peaks of Haguro-san, Gas-san, and Yudono-san. The lowest of these is Haguro-san (1,358'), the spiritual home of the Shugendo, which blends the native Shinto belief system with Buddhism and other forms of mountain worship. Continue to Gyokusen-ji Temple, allegedly founded in 1251 and its garden completed in the 1650s, and now designated as a National Place of Scenic Beauty. We'll visit the shrine at the summit of Haguro san, and descend the 2,446 steps to our accommodation for the evening.

Transfer to the start of our hike on Mount Gas-san. The highest of the three sacred mountains, Gas-san (or "Moon Mountain," 6,509') is covered in deep snow - up to nearly 20 feet - for much of the year. The mountain is officially opened each year with a ceremony at the summit's Shinto shrine. Here pilgrims in white coats head for the Dewa Sanzan shrine, with its massive thatched roof. Along our walk there are lovely small ponds formed by the melting snow and an abundance of alpine flowers.

This morning your bag travels ahead of you to Yakeyama while you and your overnight bag journey to Sukayu Onsen, in the far northeast of Honshu. Sukayu Onsen is one of the snowiest inhabited regions on earth, but thankfully the thermals caused by the dormant volcano, with their warm waters, provide an enjoyable counterbalance to the cold of the snow. The onsen is famous for its milky mineral-rich waters of its sen-in-buro, or 1,000-person bath! The bath is mixed gender, and there are also two smaller gender-specific hot springs. Please see luggage FAQ for more details on this day.

Mount Hakkoda forms part of a plateau of dormant volcanoes situated between Lake Towada and Aomori, and is known for its high-altitude wetlands. While the volcanoes of Mount Hakkoda are dormant, they do make themselves known in the area's onsen. Following our scenic walk on the mountain, travel by bus to tonight's accommodation, where your bag, sent from Haguro, will be waiting for you.

Your bag heads to Tokyo while you enjoy a half-day hike along the Oirase stream. This unspoiled area of Lake Towada is famous for its autumn foliage, but is spectacularly beautiful year-round. The stream follows the floor of the Oirase Gorge and is the only draining river from Lake Towada. During summer, waterfalls and fast-moving rapids punctuate the stream's lush greenery and virgin forests. The cedar, beech, and maple trees along its banks provide a beautiful canopy for your walk. The walk concludes with a scenic lake cruise to your accommodations. Please see luggage FAQ for more details on this day.

This morning, we will enjoy a short and easy walk to Towada shrine. You'll then have lunch before you travel by bus and then shinkansen to make your way back to Tokyo. There is time to pick up additional local delicacies to snack on as you relax on the train journey back to Tokyo. You'll arrive at the hotel in the early evening, where your bag sent from Yakeyama awaits. The rest of the day is free and you can explore Tokyo in the evening on your own.

Spend today walking in Kamakura, scenically located between the ocean and the wooded hills just southwest of Tokyo. Famous for its temples, some of which you discover today, it also provides great walking along the Ten'en trail, situated in the northern regions of Kamakura. Follow a ridgeline to Kencho-ji Temple, passing tomb caves and jizo statues as we walk through birch, maple, ginkgo, and bamboo groves. This afternoon, return to the hotel and relax. There is time to explore the neighborhood on your own before a festive farewell dinner with the group.

This morning, bid each other farewell and transfer to the airport for your flight home.
