Oita Prefecture has the largest number of tunnels in Japan with the Kakuma Tunnel, which has been selected as the location for this event, becoming the longest in Oita Prefecture at about 3 km. The tunnel began construction a while ago, but since it was not connected to the main public road, it continued construction it was not used as a huge space.

The event was initially planned as a means for people to experience various aspects of the local Yabakei region while spending time in a tunnel which had been in construction for about 15 years.

A temporary structure made of cedar grown in the local suburbs and a table made of oak trees over 200 years old that grew in a nearby temple were used to create a space for dining and relaxation. While guests enjoy the food and drinks, the DJ plays music which creates an interesting atmosphere due to the echo effect from the tunnel.

Since the road and tunnel will be open in the near future, the hotel is planned to be a one time event. However, in order to re-use the pavilion, the frame work is designed on the premise that it will be reused as a structural skeleton for an alternative accommodation event during fall when visitors will be able to see the fireflies and autumn leaves to experience Yabakei from a different perspective. By creating an opportunity for people to experience the various seasons, we hope visitors can feel the charm of Yabakei.
