I'm returning to Japan after 11 years (and 15 years before that) but have a limited time to visit friends & old favorites.
Arrive in NRT @ 1640 on a Sunday.
My goal is to go to a favorite haunt in Yokosuka called Genji.
It's right in the little "plaza" in front of Yokosuka-Chuo station (presume it's still there) with a large aka-chochin out front. Tiny place. Good food.
So I'm figuring:
1640-1800 - customs/immigration
1800-1830 - NRT express to Tokyo
1830-1930 - Keihin Kyuko express (still called that?) to Yokosuka Chuo
1930-2130 - Genji
2130-2230 - back to Tokyo to overnight to catch Shinkansen/Express to
Hakodate the next morning - I realize I could fly but would like to see the "new" shinkansen metal and also transit the Seikan tunnel that was not completed before I left Japan originally in the 70's.
So questions:
* is this possible?
* where can I conveniently dump my luggage in Tokyo so I don't need to
lug it to yokosuka
* how can I get a phone# for Genji to see if 1) they still exist 2) they
are open sunday nite

Tks.

Why not? You've got until midnight to catch the last train back. Tokyo station would be the obvious place to dump your bags.

And as for Genji, I think you're in luck:

Keikyu (Keihin Electric Express Railway Company) trains run to Yokosuka Chuo Station.

Keikyu's main station in Tokyo is Shinagawa Station. Note that Keikyu Express 急行 trains do not stop at Yokosuka Chuo, but all others (limited express, local, rapid etc) do.

If possible take a NEX (Narita Express) to Shinagawa Station instead of Tokyo Station. If you take a NEX to Tokyo, transfer to any JR line down to Shinagawa Station and transfer to Keikyu there.

Off topic, Yokosuka Chuo station is breifly mentioned in this music video about Keikyu lol http://www.youtube.com/watch?v=-JVJZTRpYxg

So things have changed on that line. When I lived there (30 years ago), there was:
- kaisoku tokyu (green kanji - fastest)
- can't remember the name (red kanji)
- kakueki teisha (black)

Anyway, is there a place to leave luggage in shinagawa?

It wouldn't add that much time (depending on where your hotel is) to check into your hotel and dump your luggage in your room. Keikyu expresses will still be running in both directions.

There probably are lockers in Shinagawa station but they are most likely outside the turnstiles. The way the transfer normally works to/from Keikyu, you stay inside the ticketed area of JR to transfer, paying the Keikyu fare at a ticket window adjacent to the turnstiles connecting the two rail lines.

Note that the Narita Express takes an hour, not 30 minutes, to Tokyo station, and a bit longer to Shinagawa.

If you are heading to Hakodate by train, be sure to enquire about the Seikan Tunnel Tour. It was quite a few years ago when I did this, so hopefully JR still offers it. There are a few trains each day that stop at one of the emergency platforms deep in the tunnel, letting off passengers who have signed up for the tour. As I recall it was about Y2,500 extra for this two hour experience.

The friendly JR staff who work in the tunnel take you into the service tunnel which runs parallel to the main tunnels to show you how they keep the place maintained & etc. There are a number of exhibits and photos of the tunnel construction, and I thought the best part was when they showed us the emergency exit tunnel. It has a cogwheel train which ascends at a sharp vertical angle up to the surface. Seeing the path of this train up, up, up was quite an eerie feeling, as you can get a feel for just how deep you are down in the bowels of the earth

Naturally, knowing Japanese is a plus, as there is no English guidance. Will you be traveling with anyone who can assist you there?
