Climate
Spring (March to May) is a very pleasant time to travel to Japan, as the flowers in bloom provide a stunning landscape, and the climate is mild, but it is also the peak tourist season; there are often many people visiting the places of interest. Summer (June to August) is fairly hot and humid in most regions, but it is still possible to visit the country, particularly in mountainous areas. Autumn (September to November) is mild, with beautiful colours that add to the charm of the landscape, but it is also rainy. Winter (December to February) is dry and often sunny, so it's a great time to take photos and admire the scenery without too many tourists. It's cold in most parts of the country (with snow in some areas), which is ideal for making the most of the famous 'Onsens', which will bring you a little warmth!
Language
Japanese people don't all speak English very well, especially outside the big cities, so writing down some useful phrases can be very handy.
Time Difference
From March to October, the time difference is CET +7, and from October to March it is CET +8.
Onsens
If you want to try out the Onsens (traditional baths), it is customary to go in completely naked (men and women are separated). Those with tattoos are not always accepted in Onsens.
Pocket Wi-Fi
Free Wi-Fi is not available everywhere in Japan. Ideally, you should travel with a small 'Pocket Wi-fi' dongle so that you have a fast connection wherever you are during your stay. This makes it much easier to check useful information or get in touch with friends and family. You can collect the box from the hotel on the first day and return it in the envelope provided at the Post Office.
Tips
It is not necessary or customary to leave tips in restaurants, for guides, drivers, etc. If you want to thank your hosts, a gift is preferable.
Driving
In Japan, cars drive on the left and the steering wheel is on the right. Gearboxes are automatic. The Japanese drive quite calmly and are very respectful of the highway code. The motorways are well maintained. To drive in Japan, you need your driving licence and a Japanese translation of it.
