During our trip to Okinawa, we found that using an iPhone was convenient, had a stable signal, fast network speed, and was reasonably priced. Before activation, you need to connect to the airport's free Wi-Fi to successfully register your SIM card.
The exchange process is very convenient and simple. There are many train services, and even unreserved seats are available both ways. It only takes about ten minutes to reach Kokura. I highly recommend it if you are going to Kokura or Moji Port.
