Traveler's Column: "Why Cell Phones and the Internet are Essential in Japan" as I actually felt it
What I realized most during my first trip to Japan in a long time,Importance of cell phones and internet accessIt was.
Not many people in Japan speak English yet, and there are many areas where signs and information displays are not written in English.
Smartphones are especially reliable when on the move.
For example, changing trains and shinkansen trains, checking timetables, and finding places to visit can almost always be completed with an application. In large cities such as Tokyo and Osaka, the transportation network is complex, and without the Internet, it is not possible to move around smoothly.
Furthermore, while the cashless society in Japan is growing, a little caution should be exercised. While touch payments with credit cards and smartwatches are convenient, we also hear news of unauthorized use.
In fact, when we tried to make touch payments for credit cards, there were several cases where we could not make touch payments, saying "For credit card payments, please insert your card. This was due to a series of fraudulent touch payments.
Safety.Real credit card and PINand be sure to check your receipts and statements at the time of use.
Also, although it may seem surprising, it is not uncommon for buses, local trains, and small stores in rural areas to still only accept cash. Fine restaurants and hotels generally accept cards, though,Always have cash on hand for small transfers and shoppingIt is safe to do so.
(Supplemental) Major convenience stores have ATMs that accept foreign credit cards.
