When the rent of a building becomes unreasonable due to the increase or decrease in tax and other defrayment concerning land or buildings, the rise or fall of land or building prices or changes in other economic conditions, or in comparison to the rents on similar buildings in the vicinity, notwithstanding the terms and conditions of the contract, the parties may demand increase or decrease of the amount of the building rent in the future; provided, however, when there is a special agreement providing that the building rent will not be increased for a certain period of time, the special agreement prevails.
建物の借賃が、土地若しくは建物に対する租税その他の負担の増減により、土地若しくは建物の価格の上昇若しくは低下その他の経済事情の変動により、又は近傍同種の建物の借賃に比較して不相当となったときは、契約の条件にかかわらず、当事者は、将来に向かって建物の借賃の額の増減を請求することができる。ただし、一定の期間建物の借賃を増額しない旨の特約がある場合には、その定めに従う。
If no agreement is reached between the parties concerning an increase in the amount of the building rent, until the judicial decision finding that the increased amount is valid becomes final and binding, it is sufficient for the party that has received the demand to pay the building rent in an amount that is found to be reasonable; provided, however, that when that judicial decision becomes final and binding, if the amount that has already been paid is insufficient, the amount of the shortfall must be paid with the addition of interest on late payments at the rate of ten percent per year.
建物の借賃の増額について当事者間に協議が調わないときは、その請求を受けた者は、増額を正当とする裁判が確定するまでは、相当と認める額の建物の借賃を支払うことをもって足りる。ただし、その裁判が確定した場合において、既に支払った額に不足があるときは、その不足額に年一割の割合による支払期後の利息を付してこれを支払わなければならない。
