PROBLEM TO BE SOLVED: To arrange a lighting fixture so as to enhance an awakening effect while making it easy for a user to check the inside of a hut. SOLUTION: A hut body 2 having an opening formed in a front portion, a chair 1 having a backrest portion 10, an opening / closing member 3 for opening / closing the opening of the hut body 2, and an opening / closing member 3 are provided along the inner surface of the opening / closing member 3. The light control member and the first luminaire 4 for irradiating light toward the light control member are provided. When the opening / closing member 3 is in the closed state, in a side view, a straight line extending in the vertical direction (the direction in which the optical axis of the first lighting fixture 4 extends) from the first lighting fixture 4 is a straight line A, a straight line A and the opening / closing member. When the intersection of 3 with the inner surface is the intersection O, the normal to the inner surface of the opening / closing member 3 at the intersection O is the straight line B, and the angle between the straight line A and the straight line B is θ, the chair 1 has the straight line A and the intersection O. It is arranged so that the angle formed by the straight line C connecting the backrest portion 10 and the upper end T of the backrest portion 10 is 2θ ± 10 °.
