>>509392743Japan used to have a bunch of companies in Nigeria because it had oil, they thought it was going to be the next Qatar. The government made deals with them to send students to study in Japan in the 90s, then they overstayed their visas and never left. Then the Japan bubble popped and Nigeria ran out of oil.
There are still remnants of that time, like they sell Pocari Sweat mineral water in Nigeria because they have some supply line set up from that time.
