KOCHI CITY, Japan — This isolated southern prefecture has no bullet trains or teams in the top professional baseball leagues. Its highways stop well short of the coasts. Only one company here is listed among the 1,700 blue chips on the Tokyo stock exchange.
But Kochi prefecture, a mountainous outpost for aging fruit and vegetable farmers, ranks among the most politically powerful places in Japan.
Kochi and other rural regions are granted disproportionate power under a national electoral system that analysts describe as antiquated and that Japan’s Supreme Court says is “in a state of unconstitutionality.” Under the system, rural areas are allotted more representatives in parliament than they ought to be based on their share of the national population. As a result, voters in rural areas such as Kochi carry more than twice the weight of those in Tokyo or Sapporo.
The imbalance is decades old, but it is intensifying as ever more people drain from the countryside into cities. It also leaves Japan with an increasingly problematic mismatch — a rigid and conservative political system for a country seeking ways to reform. The power of older, largely change-resistant rural voters acts as a head wind as Prime Minister Shinzo Abe ponders ways to revive Japan’s economy and clear its enormous government debt.
Rural and urban areas have little agreement on what’s best for Japan, a key fissure in a country that overwhelmingly supports a single party — the Liberal Democrats. The Liberal Democratic Party’s grip on power figures only to strengthen after July elections for the upper house of parliament, but the LDP’s lawmakers from rural and urban areas often fight for conflicting issues.
The priorities of those in Kochi are “completely different” from those in an urban area, said Yuji Yamamoto, an eight-term Diet member who represents a district of Kochi prefecture in the lower house.
Those in rural areas say the government should protect the agriculture industry and social security spending, two key sources of their livelihood. But some economists argue that Japan’s agriculture industry — a patchwork of small plots that produce high-quality but pricey goods — should be overhauled as part of a free-trade agreement that knocks down astronomical tariffs. The economists also say that Japan — whose population is aging more rapidly than any in the world — must slash pensions to keep pace.
“This over-representation of the elderly makes returning to a sustainable fiscal path very difficult,” Robert Feldman, Morgan Stanley’s chief economist for Japan, wrote in an April research report.
The disparity between rural and urban voters stems from the mass migration that began nearly seven decades ago and is going strong. After World War II, nearly two-thirds of Japanese people lived in the countryside. Today, by some measures, the figure is less than one-fifth. Japan’s voting system has gone through reforms, but the outlay of parliament seats hasn’t kept up with the population shift.
