Abstract
Morimoto (1993) insisted that if unit rent of wide rental house is cheaper than that of narrow rental house, it proves restrictive effect on rental housing market for general families by Land Lease Law is weak. Several papers criticized that Morimoto's view does not consider about important factors, such as locationfactor. This paper analyze correlation among unit rent, floor area, distance from central station, age of apartment house and other factors. The result support the view that even if eliminating the influence of location factor, the unit rent of wider house is cheaper than that of smaller house. In conclusion this paper points out that this fact is not enough to prove the weakness of restrictive effect on rental house market by Land Lease Law. Cost analysis is more effectiv`e to testify the effect of Land Lease Law on rental housing market.
