Living on a densely populated island slightly smaller than the American state of Montana certainly has its challenges when it comes to living space. Fortunately Japanese society is diligently organized in such a way as to have a unique process when it comes to moving. As many Japanese people do not own a car, nor the time to move their possessions to a new location, a moving service is of the utmost importance.
For many working as salary-men the company will determine when it is time to move as well as where they must move if they want to keep their job. Japanese business culture is one of unquestioning dedication, so much like American military, they will move without question to their new location. Many companies will not give them much time to move, or require it to be on their own time, which leaves them in a hard place. The solution is hiring a moving service. Services such as Moving 123 will come to your house, label everything, pack everything, move everything, and unpack everything in your new location for a negotiable price. The service can cost anywhere from US $1500 to $5000+ depending on the terms of the contract. Generally, from my experience, Americans tend only to hire a moving service if they are going across country and even then will often pack and unpack everything themselves. However, in Japan it is almost expected that you hire a service to do everything for you. Services are preferred because Japanese housing is challenging to move objects in and out in a certain amount of time. With a specialized system in place it is seen as more efficient to hire a service.
What did we do? After living in Japan for a combined 12+ years we have accumulated a lot of stuff, even after living minimalistically by throwing things out constantly. We looked at a few different services and could not justify the high moving costs given that the end of March is the busiest time of the year for moving. We were able to find an independent contractor through a friend to do it for a fraction of the price with us doing most of the work. It took about a week to pack up 50 boxes, and two days of driving back and forth to unload everything. It then took another week to unpack and organize everything. Quite a project! I could only image what it would be like if we had to maintain salary-man hours, so I could understand why they would want to pay more to deal with the entire hassle of moving!
