I have joined the society, and today I received the certificate. That's great! I think there are 86 members in my country and I am the 87th (today, the number of member in Japan shows 89 so that the other two people have joined the society after me).
I am enjoying the activity of the members, e.g. on Facebook or Flickr, etc. I also have an account on Flickr, so if you are interested in, could you please visit my Flickr page and have a look at some photos from Fukushima, where has been contaminated by low level of nuclear materials from the disastrous nuclear plant, Japan. You can search me by my account name of "hiromario".
I hope that I could see you at some meeting in UK or other country in future.
