advertisements train stations/on train

hi!

Do you know if there might be any place where posters from train stations or adverts from inside the trains are sold in Tokyo?

For example the E5,E6,E7 Shinkansen poster which is everywhere atm.

Kindly Regards, Lisa

Both are NOT sales products.

hi,

yes I know.

But maybe there are any densha-otaku-stores which might sell them.

If they're not sales products, they're not going to be sold anywhere. Take a picture, or ask a station manager if they would mind letting you know when they take it down, and if you can have it.

They are not for sale so I suppose station staffs won't give you the poster even though it has expired. I think they return posters to ads suppliers.
Those people who want the poster normally take photos of it.
Some popular idol posters such as "Arashi", "AKB48" and "J-soul brothers" are taken and stolen quickly but it's a criminal case and shameful behavior. And, some of those posters are sold at idol shops.
