Interestingly, Japan finally realized that cell phones and other electronic equipment have no effect on the airplane equipment while the plane is parked.

国交省が独立行政法人に委託した調査で、航空機が止まっている間は機器に支障がないと確認できたため、今後 は離陸前の搭乗してからドアが閉まるまでと、着陸後にドアが開いてから降りるまでの使用を認める。ドアが閉 まっている間はこれまでと同じく携帯電話は電源を切り、パソコンなどは通信しないよう求める。
Rough translation below:
In a survey commissioned by an independent administrative agency by the Ministry of Land, Infrastructure, Transport and Tourism, it was confirmed that [use of cell phones and email] are not detrimental to the plane equipment while the airplane is parked. Because of this, usage of cell phones will be allowed while passengers are boarding until the plane doors are closed, as well as after the plane doors open after landing. However, when the plane doors are closed, in the same way as it is now, cell phones should be turned off and transmitting functions of computers should not be used.
