Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

Choose the 1GB/7-day package for travel in Osaka, Kamikochi, and Takayama. It's useful for viewing maps, using Line, and has a good, uninterrupted signal. First-time users might find it difficult to understand; you may need to find additional usage information on YouTube.

Everything was great; there were no internet issues in Japan. Tokyo, Osaka, Nara, Kyoto—the internet was stable everywhere.

Rakuten Mobile was unusable in Thailand. It worked fine in Vietnam, my transit point. I quickly set up the eSIM using the hotel's Wi-Fi. After restarting, it worked immediately. It was back up and running in 3 minutes. Having no internet access while traveling is devastating; it completely destroys your vision. I was so relieved I could extend its lifespan for just a few hundred yen without having to go to a SIM shop.
