本项目坐落于日本大分县中津市耶马溪新建的隧道中，是一个供游客们放松与就餐的临时性休闲场所。

The “Yabakei Tunnel Hotel” project is an event where visitors can relax and dine inside of a newly completed tunnel in Yabakei, Nakatsu City, Oita Prefecture.

大分县是日本隧道最多的地区，此次开通的鹿熊隧道将是大分县最长的隧道，约3公里。虽然隧道的修建工程已经开始了一段时间了，但是由于没有连接到主要的公共道路，所以一直处于持续施工的状态。隧道开放前的时间有限，因此设计师并没有将该场地作为一个巨型空间进行改造处理。

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.

本项目的初衷是以一种临时活动的方式，让人们切身体验到耶马溪地区的风貌，为这条建设了大约15年的隧道赋予全新的价值。

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.

项目由一组当地郊区雪松制成的临时建筑结构，以及一张附近寺庙中生长的200多年树龄的橡树制成的长桌构成，旨在为人们提供一个用餐与放松的空间。在客人享用食物和饮料的同时，会有专门的DJ在这里播放音乐，由于隧道的回声效应，整个场地将会萦绕在一种独特又有趣的氛围中。

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.

此外，酒店还为游客们准备了露营车，供他们在此过夜，第二天早上，游客们还能够享用到当地的有机面包、蜂蜜与咖啡。

Guests are also provided a camper van to stay the night and enjoy local organic bread, honey and coffee in the morning.

由于道路和隧道将在不久的将来开放，本酒店计划被设定为一次性活动。本项目中的临时结构均是以可持续发展为前提设计的，这些木制框架将作为酒店秋季露营活动的基础结构被再次利用，届时游客将会欣赏到枫叶与萤火虫，从不同的角度体验耶马溪的风情。设计师希望为人们创造出体验不同季节的机会，让人们进一步感受到耶马溪的魅力。

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.
