Joetsu Shinkansen train schedule

Does anyone know what times the Joetsu Shinkansen train leaves from Tokyo toward Niigata. We cannot find it anywhere online. Are there multiple times it leaves each day and how does one get to the train from Narita airport. We are trying to plan a trip in December. Any links that work would be appreciated.

Thanks,
Allen

You can look it up here:

Enter "Tokyo" and "Niigata".

There are usually 1-2 trains per hour. They are named "Toki" or "Max Toki".

here is time table for JR Limited Express train and Shinkansen

Thanks for the information. Is it easy to get from Narita airport to where the Shenkansen leaves for Niigata?

Both terminals at Narita have their own railwaystation. Take the JR Narita Express to Tokyo station and there change to the shinkansen. There is a slightly cheaper ( around Yen 1000 ) way by Keisei railway to Keisei Ueno and from there walk to Ueno station, Ueno station is a stop of the shinkansen to the north, but this I do not recommend for a first time visitor. Change at Tokyo station is far more easy.

a quick look on Google confirm that the Joetsu starts at the Tokyo station (there is a station actually named Tokyo) and stops at Ueno station on its way . Tokyo station is reached by JR from Narita. It is a huge station and can be confusing.
To go from Narita to Ueno one can take the Keisei private railway co (not JR). its Ueno terminal is 5 minutes from JR Ueno, a smaller station than Tokyo station but busy enough as it is. Your choice!. With some patience one can get the various stations maps and lay out on google. As an aside, major airports in Japan and Europe are linked by frequent trains to their country long-distance trains.

Going via Ueno is slightly cheaper and can be slightly faster. But in my opinion, the transfer at Ueno Station is both, more time consuming and more confusing in terms of directions and ticket purchase than the transfer at Tokyo Station.

I would just take the Narita Express from Narita Airport to Tokyo Station and then transfer to the Joetsu Shinkansen there.
