During my last trip to Japan, I decided to use the Japanese portable Wi-Fi from Mobal , and honestly, it made life a lot easier. Before, I was constantly running around looking for free Wi-Fi, but with this one, I just took out the device, turned it on, and I was good to go. I especially liked that it didn't drop even in places where the network is usually weak: underground passages, small villages, and the narrow streets of Kyoto. I'm happy with my choice.
