Going to Japan soon!

Hi everyone! I’m planning a trip to Tokyo soon and I’m definitely going to be spending a day in Akihabara to check out the card shops. I'm actually new to the hobby, so I'm still learning which sets are which. I'm hoping to pick up a few sealed boxes while I'm there to start my own collection and maybe a few extras to trade or pass on to others here in the community. What are the most hyped or must-have Japanese sets right now? I want to make sure I’m looking for things that are actually popular.

Thanks in advance for the help!"
