Mede

Mede positions itself as a value option, combining dual-network access (both Rakuten and KDDI) to maximize coverage and speed across Japan. They also throw in SmartDelay flight lounge access for a small premium, and their 180-day 50GB plan ranks among the best value per gigabyte available.

Budget travelers and frequent flyers find Mede appealing, especially the lounge perk that can justify the eSIM spend alone on a long-haul trip. The dual-network backup means if one carrier hits congestion in your location, you'll often have a second option without switching plans.
