That place is Numajiri Kogen Lodge, a tranquil retreat nestled deep in the forest, and Extreme Onsen, an unparalleled experience for those who seek the ultimate thrill in nature.<\/p>\n\n\n\n<p>Numajiri Kogen Lodge feels like a private villa tucked away in the woods. Here, there is no rush of time, no trace of daily commotion \u2014 only a gentle harmony with the surrounding wilderness. As you gaze out at the meadow and forest beyond the window, the fast-paced rhythm of city life slowly fades away.<\/p>\n\n\n\n<p>Then, the next day brings a completely different kind of experience: trekking through mountains, descending into valleys, and immersing yourself in a wild open-air hot spring where the natural spring water gushes directly from the source. It\u2019s an awe-inspiring adventure \u2014 a&nbsp;<strong>true journey<\/strong>&nbsp;that can only be lived by stepping fully into nature, far beyond the reach of ordinary sightseeing.<\/p>\n\n\n\n<p><strong>Healing and adventure.

Throughout her life, she had a deep affection for the natural beauty of Numajiri, often setting out from here to explore the surrounding peaks.

Farmers with well-tended fields produce vibrant, lively ingredients. When food is nurtured with care, it changes the flavor of the dish itself.&#8221;<\/p>\n\n\n\n<p>The seri (water dropwort) used in the hot pot comes from an organic farm in Miyagi with whom the chef has worked long before <em>seri-nabe<\/em> became famous in the region. The seafood is delivered directly by a junior fisherman, who brings only what is needed each day. It\u2019s this trust and close relationship with producers that forms the very foundation of the dining experience.<\/p>\n\n\n\n<p>What impressed me even more was the chef\u2019s dedication to <strong>rice and water<\/strong>.<br>At Numajiri, they use rice from a contracted farm in Inawashiro, carefully dried using the rare traditional \u201cfusagake\u201d (sun-drying) method. By taking the time for natural drying, the rice\u2019s sweetness and aroma are greatly enhanced. For the corn rice, three types of corn are blended \u2014 sweet white, chewy red, and umami-rich yellow \u2014 then cooked according to the day\u2019s weather and the expected timing of the meal to achieve optimal flavor and texture.The spring water from underground, ideal for pairing with the dashi broth, further enhances the taste of vegetables and seafood, creating a perfectly balanced foundation for the cuisine.<\/p>\n\n\n\n<p>&#8220;Ingredients from Fukushima and the Tohoku region are naturally flavorful on their own. That\u2019s why we avoid excessive seasoning.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hinotori-trip.com\/media\/wp-content\/uploads\/2025\/11\/DSC06135-1024x683.webp\" alt=\"\" class=\"wp-image-26248\"\/><\/figure>\n\n\n\n<p>At the heart of the cuisine lies a philosophy of <strong>respecting the land and the seasons<\/strong>.<br>At this high-altitude location, the progression of the seasons differs from that of the Kanto region. For example, the sweetest corn comes <strong>after Obon<\/strong> (mid-August), when the cool mornings and evenings draw out the natural sugars in the vegetables. This creates a flavor of the season that <strong>can only be experienced here<\/strong>.<\/p>\n\n\n\n<p><em>Cooking in the city is fine, of course, but here there\u2019s a sense of change.<\/em><em><br><\/em><em> You can feel it every day \u2014 today it\u2019s chilly, or autumn is approaching.<\/em><em><br><\/em><em> Because of that awareness, the cuisine can remain truly in tune with the seasons.&#8221;<\/em><\/p>\n\n\n\n<p>The head chef also tends a small garden on the lodge grounds, and hopes to one day offer an experience where guests can harvest their own vegetables for breakfast. Living in harmony with nature and capturing the changing seasons on a plate \u2014 this dinner was more than just a meal; it was a moment to taste the very life of the land and the people who nurture it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"onsen-healing-surrounded-by-forest-and-breeze\"><span class=\"ez-toc-section\" id=\"Onsen_%E2%80%94_Healing_Surrounded_by_Forest_and_Breeze\"><\/span>Onsen \u2014 Healing Surrounded by Forest and Breeze<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hinotori-trip.com\/media\/wp-content\/uploads\/2025\/11\/DSC06191-1536x1024-1-1024x683.webp\" alt=\"\" class=\"wp-image-26185\"\/><\/figure>\n\n\n\n<p>With the lingering flavors of dinner still in mind, I made my way to the lodge\u2019s onsen.<br>The baths are fed by Numajiri Motoyu, a hot spring with a history of approximately 400 years, flowing directly from the source.
