Swertia japonica was cultivated for two years in various seeding densities (0.25, 0.50, 0.75, 1.00 and 1.25 g/m^2). For the first year of cultivation, the number of the plant was positively correlated with the seeding densities. For the second year it was also positively correlated with the seeding densities up to 1.00 g/m^2. The number of branches, the number of flowers, and fresh and dry weight of the plants however decreased with the increase of seeding density. Yields of the plants were about the same when they were seeded at seeding densities of 0.50-1.25 g/m^2. No significant difference in the total content of bitter components (amaroswerin and amarogentin) was observed among the plants cultivated at the seeding densities of this range. The optimum seeding density for the cultivation of S. japonica is, therefore, suggested to be about 0.50 g/m^2.
