The table is in order of championship odds. 'Standing' is the place in the official league table.
The Japan Series is contested by the champions of the Central and Pacific Leagues, which makes the championship a single race across both leagues. There is always exactly one champion, so the 12 clubs' odds add up to roughly 100% (displayed values are rounded to one decimal place, so the sum can drift slightly from 100%). One table rather than two lets that single, 100%-in-total race be compared directly.

Compared with the Japan Series odds, the values are the same or lower.
A displayed 100% or 0% is the result of rounding to one decimal place and does not necessarily mean mathematical certainty or elimination.
