When moving out, notify the landlord as soon as the moving-out date is decided. Usually, people ask the movers do the actual moving-out tasks. Make sure to cancel utilities such as electricity and gas. Clean the room; do not leave the garbage behind.

You need to notify the landlord of terminating the lease contract within the period stipulated in the contract (usually one or two months in advance).

There are many movers in Japan. Besides professional movers, cargo distributors also offer moving-out services. The rate varies according to the cargo volume, distance, and service contents. For example, you might ask the movers to do everything from packing to loading and unloading, or ask only a part of the entire process. You may be advised to have estimates from several movers and confirm the rate and service contents in order to choose the mover that meets your need. Estimates can be compared by using the Internet and other means.
There is also an option of not using the mover, by renting a car from a friend or lease company.

Make sure to notify the company at least two or three days prior to moving out.
