Total value of exports by country to world (% of GDP), Japan, 1868 to 2014

Figure illustrates how dyadic and national estimates of the total value of exports by country to the rest of the world compare. Dyadic trade may not present a
comprehensive account of a nation's trade activities. Aggregating partner trade does not translate into national figures as trade flows to categories such as 'Other
trading partners', amongst others, may be excluded from bilateral trade figures.
