A laundry system (1) includes a home terminal device (3) and laundry apparatus (4). The terminal device includes a first short-range communication device (8), a long-range communication device (7), and a terminal device controller (9) transmitting information about laundry and information about a laundry constraint to a server (2) connected to an Internet (5), thereby obtaining an operation control program for the laundry apparatus. The terminal device controller transfers the obtained operation control program via the first short-range communication device to the laundry apparatus and receives via the first short-range communication device information about an operating state of the laundry apparatus. The laundry apparatus includes a second short-range communication device (15), a laundry apparatus controller (17), and a laundry unit (16). The laundry apparatus controller receives the operation control program via the second short-range communication device from the terminal device to control the laundry unit and transfers the information about the operating state of the laundry apparatus via the second short-range communication device to the terminal device.
