Welcome @Spyder to the forum, and welcome back to the collecting hobby, very lovely to have you onboard. This place is a really great resource and knowledge base for all things Pokemon card collecting. I hope we can get to know you a lot more as the days go on.
If you are looking for Japanese promos, the two threads above should get you started. I hope this can really take you back to what collecting was in your childhood and you will probably find something interesting to pick up.
Hope you have a great time here and will see you around.
