What are they actually like? Are they just flat black coffee, milk added, sweet or raw? I associate cans with carbonated beverages, but I'm assuming it's not carbonated coffee?
They actually have some of that brand's offerings at my local supermarket, but not being much of a coffee drinker - and not knowing what to expect - I haven't felt the need to try one yet...
Totally missed this...they are mostly flat/still and all pretty sugary, even the low sugar optins. Most have milk (the milks from Hokkaido or koiwai farm for example are clearly branded) or powdered milk (you can often taste the caramlised flavour of the powdered milk). Most brands have heaps of different roasts, blends, sugar amount, milk ratio, etc. The can design is also pretty important! The shape, size, texture, colours, and so on can get very complex.
Wat are they actually like though? Like a delicious caffeine filled drink that may or may not be coffee! Most brands also make various soups in a can and hot chocolates.
The Boss (a Suntory product) cans in Australia are ok, but I think they taste very different to what is made in Japan.
Here's one of their adds
A guy I work with drinks cold brew and tonic water.
Soda water and espresso shot used to be called a Boston boiler.
Nitro cold brew is awesome.
Putting a hot can in you jacket pocket for that first icy chairlift on a snowy day feels fantastic.
