Komaki Onsen (古牧温泉)

Introduction: The Festive Spirit of Aomori and the Floating Sanctuary of the “Uki-yu”

Located in the historic aviation city of Misawa, in the eastern heart of Aomori’s Nanbu region, lies Komaki Onsen (古牧温泉). Once a vast park known for its incredible scale, this hot spring enclave has evolved into one of Japan’s premier cultural destinations under the stewardship of Hoshino Resorts, now famously known as “Hoshino Resorts Aomoriway.” Komaki Onsen is defined by its vibrant celebration of the “Aomori Spirit”—specifically the energy of the Nebuta summer festivals. For the international traveler, Komaki Onsen offers a “Total Cultural Immersion.” It is a place where you can soak in mineral-rich alkaline waters in a bath that appears to float on a scenic pond, witness the roar of traditional drumming and flute music, and explore a massive parkland filled with heritage buildings. Whether you are looking for a high-end luxury retreat or a spirited encounter with Japan’s northern folk traditions, Komaki provides a warm, energetic, and visually spectacular sanctuary.

Key Information Table

The Healing Waters: The “Uki-yu” and the Silk of Misawa

The water at Komaki Onsen is a high-quality Alkaline Simple Spring. Pumped from deep subterranean layers, the water is crystal clear and notably “soft” on the skin.
The Beauty Effect: The weak alkalinity act as a natural cleanser, gently emulsifying skin oils and leaving your body feeling exceptionally smooth—the definitive “Bijin-no-yu” (Beauty Water) sensation.
The Uki-yu (Floating Bath): The centerpiece of the resort is the “Uki-yu” outdoor bath. Designed to look as if it is floating on a massive koi pond, the bath is surrounded by forest. In winter, as the steam rises and the pond surface freezes, traditional Nebuta lanterns are floated on the water, creating a surreal and spiritual atmosphere. The minerals are particularly effective at soothing the nervous system, making it an ideal “reset” after the stimulation of the resort’s festival performances.

Nore-sore Shokudo: A buffet-style restaurant designed like a traditional farmhouse, serving world-class Misawa Squid and local beef.
Ichigo-ni: A luxury seafood soup featuring sea urchin and abalone, a traditional delicacy of the southern Aomori coast.
Vegetarian/Vegan Survival:
For Vegans: This area is a leader in Soybean and Garlic production. At the resort, request the “Vegetable-focused Kaiseki” and notify them at least 5 days in advance. The nearby farmer’s markets sell fresh seasonal corn and the famous “Misawa Garlic” which is 100% vegan. We recommend trying the local “Nambu Senbei” (wheat crackers)—ensure you check for meat extracts in the savory versions.

Cultural & Historical Context

The name “Komaki” refers to the historic horse-breeding pastures that once occupied this land. Historically, the Nanbu region was famous for its elite samurai horses. The onsen was developed in the late 20th century by a visionary businessman who wanted to create a “Disneyland of Aomori Culture.” Today, under Hoshino Resorts, it has become a global ambassador for Aomori’s identity, preserving the music, dance, and thermal heritage of the north while introducing them to the modern international audience.

Practical Travel Tips for International Visitors

2025-2026 Latest Updates

In 2025, Komaki Onsen launched the “Nebuta Float-building Experience,” where guests can learn the art of paper-lantern construction from master artisans. For the 2026 season, a new “Starlight Night Cruise” on the resort’s pond is being introduced, featuring traditional flute music played under the stars after the evening bath.

Safety & Manners

In the onsen, always rinse your body thoroughly before entering the tub. Because the “Uki-yu” bath is positioned on the pond, never attempt to swim out of the tub into the pond. In the park, be mindful of the local wildlife—Northern Foxes are common; **do not feed them**. Finally, respect the quiet of the guest rooms after the 9:00 PM festival performances to allow everyone to enjoy the peace of the Nanbu night.
