Rakumani

Japan travel guides that get the numbers right

We run 楽マニ (Rakumani), a Japanese comparison site that tracks mobile plans, credit card rewards and cashless payments every month. These English guides apply the same fact-checking discipline to the questions visitors from Singapore, Vietnam, China and beyond ask most: how to get online, and how to pay.
