Navigating politics is never easy, but it used to be a lot simpler within the confines of Nagatacho — Japan’s political center.

For the better part of the last 70 years, when the Liberal Democratic Party picked its party president, the LDP-controlled parliament would hold a vote to make that person the prime minister. When the party’s dominance started to wane in the 1990s, the LDP formed a coalition, and the same process applied.

But when Komeito decided to break from its 26-year coalition with the LDP last week, things became ever more complicated. Now, what exists is a negotiator’s nightmare as Japan’s top politicians have about a week to figure out their party’s and their country’s future.
