Our tour guide, Ada, was very accommodating and gracious despite being a few minutes late during meet-up. She also made sure that I did not miss out on any activities by asking if I wanted to go to a specific place or try doing an onsen bath. She also explained clearly why we are not able to go to Mt Aso and suggested an alternative instead. Apart from that, the combination of places that we went to were really amazing! My faves were the Kamishikimi shrine and Kurokawa onsen. I really wish we had more time at the shrine though - the vibe of that place was just magical ❤️Overall, the tour the was very worth it for its price. Highy recommend!!

The route from Tokyo to Nagano, Hakuba, Kamikochi, and Takayama had internet access throughout. I was able to make Line calls and use Google Maps for directions for all 7 days. Compared to my partner who used roaming, the usage, price, and quality of the eSIM were superior in every aspect.

The Mobile Data works very well in Hakodate, Otaru and Sapporo. Even during attending King Gnu’s concert in Makomanai Sekisui Heim Ice Arena, the connection is still very stable. This makes me feel enjoyed and happy for the whole trip. Definitey will choose this plan for my next Japan trip.

Very convenient and easy to set up! Used it for 7 days in Tokyo and the signal was reliable for maps, social media, and messaging. Worked immediately after landing. Much easier than using pocket WiFi. Recommended!

Absolutely loved using this eSIM! It is completely hassle-free, budget-friendly, and way more convenient than traditional SIM cards or renting a pocket Wi-Fi. The data speeds were excellent, and the activation instructions were clear and straightforward. I will definitely be using this for all my future travels!
