Certain rules have been introduced with regard to the commercial industry (especially retail of daily products). Among others, mandatory closing of stores has been introduced and is effective as of March 15, 2015. Stores, unless being exempt from such rules (e.g. shopping mall, cinema, restaurant, pharmacy, stores at or around railway station, etc.), can be opened on trading days (i.e. from Monday to Saturday except public holiday, but including working days defined by the law) between 6.00 and 22.00 and must be closed on Sundays and public holidays. However, opening (i) on Sundays of the Advent period from 6.00 to 22.00; (ii) on December 24 and December 31 from 6.00 to 12.00; and (iii) on one Sunday appointed upon discretion from 6.00 to 22.00 is permitted; but cases under (i) and (iii) are permitted subject to prior reporting obligation to the commercial authority. As a result of this rule, in case such stores are operated under a lease agreement, the new opening hours may affect the rent payable for the lease of stores on the entire market and lessees might assert claim for rent reduction against their lessor. Also, it seems probable that market value of certain locations will increase due to the fact that they are not subject to the above rules (e.g. at or around railway station).
