About US


What can we do to "omotenashi" an increasing number of visitors from overseas?
as for being a hospitable host of an island in Japan?

In the close future, the concept of international distance will be no greater than it is today.
We think that our profession as a multi-lingual field guide should be recognized now,
as one of the indispensable roles to be played by younger generation.

So we started, as a group of professionals in Yakushima,
to help you all who are interested in Yakushima and our job!

For all tours

  1. When an official Warning for Heavy rain (Ground-loosening) is warned in Yakushima area by Japan Meteorological Agency, we cancel or postpone our tour concerning any activity outdoor.

    Frankly speaking, torrential rain could cause in the mountain area a partial landslide that can easily carry your life away.

    This guideline is followed and respected by all the tour guides and companies in Yakushima.

For trekking

  1. When the wind speed records over 18 m per second at a height of 2,000 m above Yakushima according to Japan Meteorological Agency’s Wind Profiler, we cancel or postpone our trekking tour concerning Mt. Kuromi or Mt. Miyanoura.

    Frankly speaking, strong wind in high altitude could take your body temperature away, and possibly freeze you to the icy heaven.

  2. When the route or trail concerning our trekking tour is closed by Yakushima’s municipality due to the natural condition, we cancel or postpone our tour, or change our tour content.

    We are locals and obligated to cooperate with our local authority, in order to keep all the visitors away from probable danger.

For kayaking

  1. When the lightning is observed while kayaking, all the participants will be advised to paddle under the protective objects, such as trees or bridge, or walk into the forest for better safety. If the lightning still continues on flashing, we stop the tour and return by walking on the bank.

    However, while the heaven flashing, usually our guide serves you a cup of coffee at a safe spot and we enjoy talking in an unusual situation. This could be another experience. So please always follow our guide’s instruction.

  2. If the water is muddy colored and its current is stronger than usual at the time before starting, we cancel our kayaking tour.

    The transparency of the water is closely related to anticipated rainfall. We take these elements in consideration for better safety.

For stream climbing

  1. One particular rock is always set for our “standard”. If the water flows over the rock in the morning of the tour date, we cancel our stream climbing.

    This is exclusively our safety guideline. The decision is made even when an official Warning for Heavy rain (Ground-loosening) is NOT warned in Yakushima area by Japan Meteorological Agency.

  2. If the water turns to muddy color even slightly on the way, all the participants will be advised to walk on the river bank/edge, or evacuate into the forest.

    A change in transparency of the water can be a sign for probable flash flood. We take in consideration multiple elements such as transparency and volume of the water, always observed along the time process.

  3. In addition to what is mentioned in the preceding paragraph, if the water level goes up by 5-10 cm compared to how it was at the starting point, an observation time is held about 30 min. After this observation, our guide will make a decision with much caution, whether we restart climbing or not.

    Frankly speaking, a subtle change in water level while stream climbing is hardly observable unless you know very well this particular river in Yakushima. However, it is a matter of life and heaven. So please follow our guide’s instruction.
