I traveled to Tokyo on a business trip a few months ago and had a little free time between meetings. Before leaving, I read Tax-Free Shopping in Japan : The Complete Guide because I wanted to understand how the process worked and avoid confusion at the stores. The guide was actually very useful and saved me some time. I also decided to use a Mobal eSIM during my stay. Having reliable internet made it easy to check directions, communicate with colleagues, and quickly look up information whenever I needed it.
