Lamune Onsen, situated in Taketa, Oita Prefecture, is renowned for its naturally carbonated hot springs. The name "Lamune" is derived from "ramune," a Japanese carbonated soft drink, reflecting the effervescent quality of the onsen's waters. Bathing here is akin to soaking in warm, fizzy soda water, with tiny bubbles clinging to the skin—a unique sensation among Japanese hot springs.

The onsen's architecture, designed by Terunobu Fujimori, features charred wooden exteriors and whimsical elements, such as a statue of an elegantly dressed dog in the front garden. This design harmonizes with the surrounding rural landscape, enhancing the overall experience.

Bathing Experience:

• Water Temperature: The carbonated baths maintain a temperature of approximately 32°C (89.6°F), cooler than typical hot springs. This allows for longer, more refreshing soaks, especially during warmer seasons.

• Facilities: Lamune Onsen offers both indoor and outdoor baths, with the carbonated spring located outdoors. The interior features a vaulted ceiling, creating an airy atmosphere, while the outdoor bath provides a natural setting to enjoy the effervescent waters.

Access:

• By Car: Lamune Onsen is accessible by car, with parking available on-site.

• By Public Transport: From Bungo-Taketa Station, local buses run approximately hourly, taking 30-40 minutes to reach the Yamawaki bus stop. The onsen is visible from the bus stop. It's advisable to check the latest schedules in advance.

Visitor Tips:

• Seasonal Considerations: The cooler temperature of the carbonated baths makes Lamune Onsen particularly enjoyable during warmer months. In cooler seasons, alternating between the carbonated bath and warmer indoor baths can enhance comfort.

• Etiquette: As with all Japanese onsens, it's customary to wash thoroughly before entering the baths. Tattoos may be subject to local policies; it's recommended to inquire beforehand if you have visible tattoos.

Experiencing Lamune Onsen offers a distinctive take on Japan's onsen culture, combining unique carbonated waters with thoughtful architectural design. It's a destination that provides both relaxation and a touch of whimsy in the heart of Oita Prefecture.
