In my case, there is a before and an after my first trip to Japan, it is certain that Japan will not leave you indifferent. It is a culture, a philosophy that is truly unique, based on collective spirit, discipline and in opposition to self-centeredness.
Everything is so organized and rigorous that you can even follow the metro station by station on your smartphone (compared to France, we are really light years away). Another extremely memorable thing (and still in total opposition to France) is cleanliness, not a single garbage in the streets and yet we could eat on the floor.
A truly magical, welcoming and unique country. In addition to the Sakura season you can also go there in autumn when the parks are bright yellow and red ;)
I wish you could go there :)
