3. When's the most popular time for expats to move to Tokyo?

For the most part, expat relocations to and from Japan occur at a consistent rate over much of the year.

However, families with school-age children do tend to move the most during the summer school break (June – August), so that the children can start attending their new schools from the beginning of the school year, in September.

Expat moves to Tokyo generally tend to slow down a bit in October, pick up some in November, then grind to an almost total halt in the latter half of December and first few weeks of January, for the holiday season.
