I want to buy Chunichi Dragons tickets.
In the first photo, 内野ＳＳ１塁側 means the seats are near first base?

Please look at the link below.

In the second photos, there are multiple seat numbers listed.
Those two are next to each other, correct?
I need two sets next to each other.

８ゲート １４通路 Ｒ２０列 126番
８ゲート １４通路 Ｒ２０列 127番

In the US, I was able to look at a map and pick my seats.
Is that not possible here?
I want to buy my friend REALLY good seats for his birthday.
But I can't tell if the seats are good without looking at a map.

Input that seat number, then click 検索(kensaku =search) button, very easy.

内野(nai-ya) is infield, position number 1 to 6 is so.

Position number 7 to 9 is 外野(gai-ya) = outfield.

That game date has already entered the rainy season(called 梅雨 tsuyu),
and depending on the standing of DeNA, the number of fans may be not so much.
Immediately after payday may also have an impact.

And usually we use "Dragons" than Chunichi, not only in local.

DeNA is called DeNA now,
but many old fans are still using home studium city name "Yokohama".
Also "CENTRAL LEAGUE" is shoten "Ce(セ=Se) LEAGUE",
"PACIFIC LEAGUE" is "Pa(パ) LEAGUE" usual.
