新江古田
Shin-Egota
(New Egota)

I’m going to give an oversimplified explanation of this etymology. There was a station called Ekoda Station. Later, a New Egota Station was created[i]. If Ekoda and Egota look different to you, then you’re normal. They are. This place name may warrant its own article, so I’ve added it to my to-do-list.
At any rate, the station is located near the border of Nakano Ward and Nerima Ward. It’s a residential area. No need to go there.

I wrote a whole article about this place that was very thorough. The history of this place name is pretty much a mystery, but there are a variety of theories. I suggest you click the link below if you’re interested in the etymology.
In the Sengoku Period, this area was controlled by the 豊嶋氏 Toshima-shi Toshima clan. In the Edo Period, this was all country – mostly farmland located well outside of the city limits. Today Nerima refers to one of the 23 Special Wards, so the name applies to an area much larger than the immediate station area. Supposedly, Nerima is the ward that can boast the most farmland. Woo-hoo.

As for the area modern area, I don’t know much. I’ve been to Nerima Ward before but never Nerima Station. My impression is that it’s a local shopping district with restaurants, small shops, and some department stores.

- The ruins of Shakujii Castle are in Nerima (but not at Nerima Station)
