Sumo Spring Schedule

The list for the spring schedule was released today.

(http://www.sumo.or.jp/eng/jungyo/schedule/index.html)

But I do not know how to get to these locations:

1. Fujisawa (Kanagawa Prefecture)
2. Iruma (Saitama Prefecture)
3. Hadano (Kanagawa Prefecture)

Also, are these events free of charge?

But I do not know how to get to these locations

It obviously depends on where you are coming from.

The closest station to the Fujisawa stadium is Shonandai Station along the Odakyu Enoshima Line.

The closest station to the Iruma stadium is Irumashi Station along the Seibu Ikebukuro Line.

And the closest stations to Hadano are Hadano and Shibusawa Stations along the Odakyu Odawara Line.

Also, are these events free of charge?

No, the price depends on the type of seat and on the event. They tend to be popular and might already be sold out.

The following website let's you look up train routes:

Also, how do I know when each event begins?
The exact location from the station is also unknown.

Is this a good place to get sumo wrestler's autographs?
