In Japan, there are a lot of Personnel revisions in March.
We usually attend many farewell parties in March. However there are not so many parties in this year, due to the big earthquakes.
A person, who moves to another company, or another section, usually gives a small gift to the members of the same department, or the members of working with him.
It is one of Japanese ‘salaryman’ customs.
The small gifts are sometimes handkerchiefs, a pair of socks, cookies and so on.
In some cases, the members of his section give him a present.
In that case, the gift is a bouquet, tie, business bag or ballpoint pen with his name, and so on.
If he is an age-limit retirement man, a bouquet is a good souvenir, even though he is an old man.
I think those gifts are one of means to reveal their thanks!
