When I arrived in Tokyo I saw some stamp booklets that allowed you to collect different Pokémon Stamps at different stations. To start with I didn’t think I would visit enough but after the first day, I decided it wouldn’t be too difficult and I would have had 6 if I’d started straight away and 3 planned for the rest of the day. As I was a bit late to the game, I decided to make some deliberate stops on en-route home to get the 6 stamps so I didn’t need to think about it later.
It took a few days to be in the right place to claim the prize but I made sure to find the Goal Station in Tokyo station and get the Pokémon ticket holder!
