What British gifts should I get for my Japanese colleagues? (First time meeting them)

Hi everyone,

In a few weeks I'm moving to Japan for 8 months to work in a lab. It'll be the first time I meet everyone, so I want to make a good impression. I was thinking of bringing gifts but I don't know what. I'm from England and don't know what they'd enjoy from here. Any ideas, from trinkets to food, would be appreciated.
