①When the right of the superficiary is extinguished, the superficiary may restore the land to its original state and remove structures and trees or bamboo on the same; provided, however, that if the owner of the land gives notice that the owner will purchase the same by offering to pay an amount equivalent to the market value, the superficiary may not refuse that offer without reasonable grounds.

②If there are customs that differ from the provisions of the preceding paragraph, those customs prevail.
