(2) Many third-party roaming eSIMs tunnel data through Singapore or Hong Kong before reaching Japanese websites, adding 70–120ms of round-trip latency and occasionally triggering geo-blocks on Japanese streaming or restaurant booking portals (such as Tabelog or Radiko); (3) Nomad partners with IIJ (NTT Docomo MVNO) and KDDI, offering low-latency Japanese routing on its Regular Fixed-GB plans.","beforeYouFly":["Install your Japan eSIM profile on home Wi-Fi the day before your flight;
