Golden Week in Japan (In titles, prepositions do not take capital letters)

This week is Golden Week, one of Japan's three busiest holiday seasons, the other two being New Year and Obon.
Many Japanese people will do domestic and international travel. (This makes sense but it might be better to say 'Many Japanese people will travel within the country and internationally')
Trains, airports and sightseeing spots get very crowded during Golden Week.

Well done! What celebrations are there in Golden Week? :)
