Ryugado, known as the “Dragon Cave,” is one of Japan’s three major limestone caves.

Formed over hundreds of millions of years, the cave features impressive stalactites, underground streams, and traces of ancient human life.

In Japanese culture, dragons are water deities, and caves like this were once believed to be their dwelling places.

Walking through the cave offers a fascinating blend of geology, history, and mythology.

Optional Adventure Course at Ryugado Cave

An optional adventure-style course may be available at Ryugado Cave for guests seeking a more immersive experience.

This course requires a separate fee, which is set by the cave and confirmed individually depending on the date, group size, and conditions.

If you are interested, please let me know in advance and I will check availability and the exact cost for your tour date.

Ioki Cave is a narrow valley surrounded by cliffs and filled with moss, ferns, and clear flowing water.

While Ryugado reveals the underground world shaped over hundreds of millions of years, Ioki Cave offers a glimpse of Japan’s living forest landscape, where water, plants, and rock coexist in quiet harmony.

The short and gentle walk makes it suitable for most visitors, and together these two locations create a rich contrast between subterranean geology and vibrant surface nature.

Enjoy a relaxed lunch at a local restaurant along the way, selected based on the day’s route and your preferences.

This is a chance to experience everyday regional food enjoyed by locals, using seasonal ingredients from the surrounding mountains and coast.

Simple, authentic local dishes

Flexible options depending on dietary needs

A comfortable break between nature and cultural sites

Lunch is not included in the tour price, allowing you to choose freely according to your taste.

Dietary Requirements

Please let me know in advance if you have any food allergies, dietary restrictions, or preferences (such as vegetarian, no raw fish, or no pork).

I will do my best to select a suitable local restaurant and adjust lunch options accordingly. While choices may be limited in rural areas, I always prioritize safety and clear communication with the restaurant.

>>>Option A – Local Onsen Experience

Umaji Village Onsen

Visit a small, rural hot spring in a mountain village known for its yuzu citrus.

This is a calm, local-style onsen experience that reflects everyday life in the Japanese countryside, rather than a large resort setting.

Choosing the onsen option, the reservation will be arranged by the guide in advance.

The onsen experience is provided as a 30-minute private family bath, offering a comfortable and private setting.

>>>Option B – Garden & Photography

Monet’s Garden Marmottan

A beautifully designed garden inspired by the works of Claude Monet, featuring seasonal colors, light, and carefully composed landscapes.

Easy and well-maintained walking paths

Excellent photo opportunities

Relaxing and visually pleasing experience

>>>Option C – History & Storytelling

Birthplace of Yataro Iwasaki

Visit the birthplace of Yataro Iwasaki, the founder of Mitsubishi.

The traditional house itself offers an authentic glimpse into everyday life in rural Japan during the 19th century, with its simple wooden structure and original layout. Even without detailed explanation, the house alone is enjoyable to explore, while guided storytelling reveals how a man from this humble setting went on to shape modern Japan.

Insight into Japan’s modernization

Enjoyable through the architecture and atmosphere alone

Ideal for guests interested in history, business, or society
