I for one dont understand the protesters. To be honest there is nothing they can gain from going there, only incur extra losses for paying for travel (say london to Japan costs a bit)
It's not like the company is public and they have shares in it, it's private. Instead of wasting their time up there they should review their legal options.
Probably all or most of their savings are there, and they got desperate. Not rational but easy to understand. I would have paid a lawyer intead of spending with trips.
