The last city that whould be on your road trip must be Tokyo. If you want to save some money you can take a night bus to go to Tokyo. And you can be lucky to see Mount Fuji during your ride.
#8 Shinjuku & Harajuku
Wander in the streets of Shinjuku before strolling in Harajuku (be careful there is a lot of people during Golden week because it’s a national holiday in Japan). It’s a fantastic neighbourhood, you can by cute clothes, cosplay accesories and if you walk a little you will arrive to the host/hostess neighbourhood. The Takeshita street or coplayer street is really near Harajuku.
You can’t go to Tokyo without going to the famous Akihabara neighbourhood. Lost yourself in manga shops, anime, games and….maid café. While you are here why not try a maids café (like the “Queens court”). A maid café is really a special experience, if you choose a themed café (most speak english) be careful of the price for entrance/drinks/photos (it can be really expensive). It’s a unique experience.
Take the elevator to the stars. Take a walk towards the Skytree (different from the Tokyo tower) but the Skytree is perfect. Check beforehand the festival periods and be there when they shoot fireworks near the river. Enjoy a 360° city view by day and by night.
#11 Asakusa temple (Senso-ji)
In Asakusa aea you will find the Senso-ji temple which is the oldest buddhist temple in Tokyo. There is often festivals near the temple and you can find traditional, handcraft objects near the temple and the shrine.
#12 Mount Fuji (富士山)
The last things I recommend you to do if you have the time and if the weather allow you to do will be to climb the Mount Fuji ! Be careful of the season and the holidays (some facilities can be closed).
