When I was preparing for my trip to Japan, the most surprising question wasn’t the route or even accommodations, but connectivity. It seems like a small thing, but without internet it’s easy to get lost there—especially on the subway or when searching for restaurants. I spent a lot of time comparing options and realized that choosing between Pocket Wi-Fi or eSIM really impacts comfort. I found a good explanation in the article Pocket Wi-Fi or eSIM in Japan . Everything is laid out clearly, without unnecessary advertising, in a human-readable manner. In the end, I chose eSIM and haven’t regretted it for a second.
