I'm on my pilgrimage. Where's the merch?

I'm staying in Kabuchiko. Spotted the Daigo and Saejima vending machines which is great because I thought they were going to be removed by now.

Where in Tokyo can I get RGG merch? Is there any special Majima Gaiden events/merch out this week?

Edit: saw the posts about Famitsu and an-an. Will pick those up.
