- Over the weekend Japan's ruling party had chosen a new leader, one who favours government spending and low rates
- The party leader effectively becomes prime minister, so that person's leanings become national policy
- More spending means a cheaper yen and bigger profits for exporters. So shares rose

- Machinery, heavy industry and property names rose hardest
- The market gave the move a name of its own, after the new leader
