Which is larger?
Japan has a mapped area of 370,075 km², compared with 356,164 km² for Germany. That makes Japan about 1.04× larger. Because both values come from the same map geometry and spherical calculation, the ratio is internally consistent.
Which has more people?
Japan has about 1.5× the population of Germany, using the latest World Bank values imported for each country. Population years are shown beside the figures because updates do not always arrive simultaneously.
