Thanks for the link.

I remember the expression on a Norwegian colleague's face when I tried to get him to refer to Tokyo's underground railway network as "the subway" and not "the metro".

He thought I was being a dreadful pedant to insist that Tokyo's underground railway network is not known as the "metro" and "Tokyo Metro" is the corporate identity of one company that runs some subway lines.

Well... I am a dreadful pedant... but I was only trying to help.

I do think it was a mistake for "Eidan" to change its name to "Tokyo Metro".

I thought this would be perfect for me if it worked on the Toei lines. To get from Narita to my hotel, it's easier if I take the Skyliner and have to only transfer once. I'm staying at Asia Center and the closest station to it is Aoyama Itchome, so the O-Edo line (Toei) would be really convenient for me to get around.

Even though having use of only Tokyo Metro lines it seems you can still get to anywhere, I don't want to waste time if it's not necessary.

I'm guessing there's no Keisei Skyliner + SUICA bundle, so my options would be to:
1) Skyliner + Metro Pass, and live without the Toei lines
2) N'EX + SUICA, and have a slightly less convenient time getting to my hotel (one more transfer, or walk from Akasaka Mitsuke)
3) Forget the package deals and buy Skyliner and SUICA separately

I suggest getting the NEX Suica package - get the NEX to Tokyo, get the Marunouchi line Westbound to Kokkai-gijidomae, change to the Chiyoda line and go Westbound to Nogizaka station.

For convenience with the other package, avoid making a transfer from the Skyliner at Ueno (the walk takes around 10 minutes). Go to Nishi-Nippori instead and get the Chiyoda line directly to Nogizaka.

Asia Center is the same distance from Nogizaka as Aoyama Itchome

The transfers at Kokkai-gijidomae can be pretty long too and include stairs without escalators, in case you have bags.

Skyliner does not stop at Nishi-Nippori.

I suggest

(1) Take the Skyliner to Keisei Ueno.
Walk from Keisei Ueno to Ginza Line
Take Ginza Line to Aoyama Itchome

(2) Take the N'EX to Tokyo Station
Walk to Marunouchi Line subway
Take Marunouchi Line subway to Akasaka Mitsuke
Change at Akasaka Mitsuke to Ginza Line
Take Ginza Line to Aoyama Itchome

My choice as well. It is only about a block and can be done underground if you want to avoid the hawkers and scalpers on the street.

So you guys think a Metro Pass will be sufficient? I don't know how much of a hassle transfers are, but if I don't need to use the Oedo line then I'll stick with just using Tokyo Metro. If I need to use JR lines I'll just pay for it (was planning on going to Kichijoji and Yokohama).

It depends where you're planning to go. I don't think that it's a good idea to force yourself to avoid certain lines, merely to save a few pennies on fares.

Even if I had a Metro pass, I'd probably still buy a SUICA on the first occasion that I wanted to ride a non-Metro train.
You can get a refund on the SUICA at the end of the trip. In the worst case, you may lose ¥210 (JR's charge for refunding unused credit). If you're smart, you'll find a way to run the stored credit down to zero before asking for a refund on the deposit (no charge for that). To me, the added convenience is worth it.

Yeah, a SUICA seems more convenient. If that's the case, I might as well take the N'EX from NRT and live with the extra transfer, then I don't have to bother with the Metro Pass at all. Maybe I can walk from Akasaka Mitsuke... anyone know how long that is to Asia Center?

It's on the map I posted if you just zoom out a bit. About 3 times the distance of getting to your hotel from Aoyama Itchome.

There are hawkers and scalpers on the street? Maybe I have been to China too much because except in Roppongi (where they are really obnoxious), I hardly ever notice them in Japan, unless I need some kleenex!

Those genuine Rolex watches for $20.00 are a great deal, as are the phone cards that are somehow already expired.

Buy Suica or Pasmo, which are good on virtually all underground and overground rail lines in the Tokyo-Yokohama-Chiba area.

They are not passes, but they are debit cards, like London's Oyster Card, that calculate your fares and transfers for you.

You don't save any money, but on the last trip, I liked being able to transfer between JR and the subway simply by swiping my Pasmo card, instead of the old routine of digging out a different card or stopping at the ticket machine.

SUICA are more typically described as stored value cards.
