Bandaid tape to cover tattoo

Hi,
Since I have a small tattoo on my shoulder I want to cover it up with some kind of skin coloured bandaid tape.

I forgot to buy back home so now I need to look for some here in Japan. Where can I find such?

It should be waterproof at least since I will be in a bath...

You can find them at any Matsumoto Kiyoshi drug store or any pharmacy.

Alrright. But what are they called in Japanese? Since I only know basic words, waterproof and so is not in my knowledge.

Say 'Big Band-aid, please! '. All Japanese people know what Bandaid is.

Alright, but are all bandaids waterproof?

The packaging will usually have a drop of water or something similar to denote waterproof, but usually band-aids are waterproof.

You can show your tattoo to the clerk and say you "kavaa shitai (want to cover)" it, and that you need a "bando-eido (bandaid)" that is "woo-taa-pu-ruufu (waterproof)".

Anyway, say all these words in Queen's English (British-style) and they would understand. But Band-Aid brand packages are basically the same all over the world.

Of course. Thought it would be a bit complicated sorry.

Just wondering, by band aid, I'd rather have one of these kinds

Than one of these

In fact I tried a waterproof band aid I bought from home last time but the thin part (where the glue is) made the tattoo visible anyway... hence the question.

Just show the photo then! Have it printed out at your hotel if you're not carrying a smartphone. Those tapes are commonly available at drug stores.

Once you have the plaster, are you OK with sticking it on?

Plaster...?
