There are basically 3 types of seats for a normal ticket.

Type 1: Arena <seat section> Block <seat no.> Seats
Kanji/Katakana: アリーナ<seat section> ブロック <seat no>番台

Type 2: Elevated Level 1 Seats (North or South) <seat section> Row <seat no.> Seats
Kanji/Katakana:　1階南(South) or 1階北(North) <seat section> 列<seat no>番台

Type 3: Elevated Level 2 Seats (North or South) Row <seat no.>
Kanji/Katakana:　2階南(South) or 2階北(North) <seat section> 列<seat no.>番台


If you are watching auctions bids, some Japanese will like to censor the seats number section on the ticket photos. I do not understands why they does this. Probably they are sly traders. But usually in the bid description you can spot the full description of the tickets (Just look out for the Kanji/Katakana words i had listed).

It's best that you try to remember these few kanji words by heart as when you go to the concert venue you have to find these seats anyway.
