yes, Jap ones always have the Taito metal plate affixed, unless someone took it off.  same with my congo, gilligans, rfm and a few others. sometimes u wish they hadnt affixed the dam metal plates.lol

All the Jap pins I bought off caveys' mate had the badges, other people I know have also bought pins off him and they all had the badges too.
I really like the Taito badges for some reason, prob becuase I associate Taito with space invaders and that time in my life when spacies came out had a big impact and lasting impression.
