PURPOSE:To create an aimed natural environment within a building, an underground area or an area sandwiched by building by providing a sunlight lighting device for guiding sunlight into an enviroment-creating space and a mist generator for atomizing perfumes to be floating over the passage of sunlight. CONSTITUTION:This invention is adapted for creating a forest bath park 2 within a building 1 and is provided with a sunlight lighting device 3 for allowing sunlight to light the above forest bath park 2 and an atomizer 4 for spraying mist on the passage of sunlight allowed to light there by the sunlight lighting device 3. The atomizer 4 has a perfume supply pipe 9 and a high pressure air supply pipe 10 connected together at its mounting portion and is so formed that it mixes perfumes and high pressure air introduced therein from the perfume supply pipe 9 and the high pressure air supply pipe 10 respectively so as to inject the above perfumes in atomized state. As the perfumes, those which may exist in a real forest such as smells of trees and flowers are used.
