Notice the price in Japan, which is an island and so all in/out-bound traffic has to go through undersea cables. Similar story for South Korea, which for all purposes is also basically an island. It's actually not even entirely uncommon for people to not have dedicated home internet and just get unlimited, unmetered, mobile service and tether when at home or use a wireless puck -- like bandwidth heavy users of streaming video. The last time we were in those areas, our AirBnBs also didn't have home internet/Wifi. The hosts just provided a puck that we were allowed to take with us wherever we went and just tether to it while in a backpack. Even though we have Google Fi, it saved a ton on mobile data and offered full 4g data speeds literally every place we went.
