LA is a good place to stay for good. However, it is also hard to give up a home in Tokyo. Moving to a home in LA from Tokyo relocation can be a daunting experience. It's one thing to mentally prepare for a new environment, and another thing to actually go through with the actual moving. Finding a new home is going to take monumental effort because of the obvious logistical issues. Even with posted ads on the Internet, it's still going to take a lot of time and effort to find a good place to live in. The Internet is just a tool, after all.
Fortunately, there are businesses with the primary purpose of helping people from far away to find an appropriate home. And by 'appropriate', meaning looking for a house with the right floor area and room requirements for the family. Same goes true for their customers who are living alone and are looking for a simple studio apartment. These businesses also take the neighborhood into account.
Even better news is that they provide extra services that are usually considered as extra value added service. Simple things like picking up their clients from the airport and accompanying them to the different locations of their options for new homes help a lot. It eases their worries about the unfamiliarity of their new locale and helps them adapt a lot faster.
