Ideal for those who prefer minimal interference and value their personal time, Modern Living Futakotamagawa requires a security deposit in addition to the rent and common service fee upon moving in. The security deposit is equal to one month's rent, but for a 1-month contract it is set at 30,000 yen and will be refunded after moving out. The ongoing monthly costs are the rent and common service fee, which are prorated if you move in mid-month. The common service fee covers utilities, internet, common area cleaning, use of the washer and dryer, maintenance fees, bicycle parking, and neighborhood association dues.
