Safe and comfortable residence make human able to settle on the moon. Safe and comfortable residences can facilitate human inhabitation on the moon,
On the surface of the moon there are numerous lava holes. A lava tube connected to a lava hole in the "quiet sea" is expected to be one of the prime candidate sites.
The hole is in a communicable place with the earth, and the temperature inside the lava tube is more stable than on the moon surface.
In addition, the lava tube can shelter humans from radiation and meteorites.

Recent studies have found that gravity is an important factor for human’s health.
This paper proposes the rotating artificial gravity facility “Lunar glass” inside a lava tube. The facility generates an apparent gravity environment through rotation. An acceleration of the centrifugal force is combined with the moon's gravity acceleration, and the resultant acceleration generates around 1G. This acceleration creates an apparent gravity force on the parabolic floor line. At each point on this floor’s surface, apparent gravity differs depending on the radius of rotation. One facility is capable of accommodating 650 residents.
The facility has a waterfront environments and artificial ocean to enable people to live comfortably.
Aquatic organisms and aquatic plants in the artificial ocean as well as vegetation on the land create a biological circulation system.
This artificial ocean has important roles as follows.
・A water storage for emergencies. Visual understanding of the amount of water.
・Enables people to understand the direction of the gravity visually.
・To give amenity in the closed environment with a natural landscape.
・To protect people from the space radiation.
