We chose Kagurazaka to start with. I am telling you why we took up it.
1)Scenic views because of hills.
Kagurazaka in Shinjuku ward boasts of scenic views. It has more than 60 Sakas(hills). As a result, you would feel many ups and downs in Kagurazaka while walking. Simultaneously, you find many temples and shrines as well as remains of a castle on the high ground there.
On the contrary, you will see the outer moat near Iidabashi
2)Traces of Geisha district and nice restaurants
Moreover, some parts of Kagurazaka were Kagai(Geisha district). You might feel the traces of Kagai while walking on the zigzag lane. Now, fancy restaurants and souvenir shops are along narrow lanes. As French language school, Athens Francais is in Kagurazaka, you might feel French influence as well. Stylish persons seem to visit here for dinner.
