Putting Japanese at such a low complexity shows a lot about the author's criteria and bias. Japanese numerals are quite easy, but when it comes to actually counting things, it is quite complex. There are two series of numeral words that are used in different contexts, as well as dozens of counter words that pair with a variety of semantic categories. Many combinations or number + noun have quite irregular combinations, like "hatachi" (20 years of age) or "hatsuka" (20th day of the month).
