Many other beverages come in cans, especially coffee and alcoholic drinks. And many of these have resealable screw tops. So why is it so rare to find tea like this?
The official color system is, according to https://www.japanpost.jp/group/about/identity/:
Three questions about where this falls apart in practice.
Blue doesn't seem to exist on exteriors. I see Red, Orange, and Green on building facades. Blue is absent. My working hypothesis is that insurance is counter-serviced rather than institutionally branded on signage; Kampo doesn't need its own exterior identity because you access it through the same physical door as everything else. Is that right, or am i just missing blue buildings?
"JP NETWORK" in orange. Found a pristine, clearly recent-ish sign explicitly labeled "JP NETWORK" in solid orange. My understanding is the branding shifted around 2012 toward "JP POST" in red as the dominant identity. So is this a legacy sign from the 2007-2012 era that nobody got around to replacing, or does "JP Network" still carry a specific operational meaning for that branch type?
No green stripe, no ATM? If a building has a pure red or orange facade with no green element at all, can i reliably infer no Yucho ATM or banking window inside? Or do smaller branches (Kan'i offices especially) run banking services under a sign that doesn't signal it externally?
Basically trying to figure out how much signal the facade color actually carries versus how much it's just legacy chaos. Or if it's just a facade.
