點由新宿去靖國神社?

樓上的朋友寫的完全正確. 用中文來表示:
從新宿出發 乘 都營地下鉄 (Toei Chikatetsu) 新宿線 (Shinjuku Line), 四個站, 九段下 (Kudan-shi-ta)下車.
出站後依路牌而行, 10分鐘左右便到達 靖國神社. 附近的名勝還有: 皇居御苑, 武道館, 千島淵

It's very easy. You do not need to change trains.

From Shinjuku you take the Toei Shinjuku Line (green) and leave at the fourth stop at Kudanshita.

From Kudanshita Station you have to walk towards the west for about 10 to 15 mins. You may visit the adjacent Budokan as well whilst you are on the way to Yasukunijinja.
