The words for tea are actually fascinating aren't they! - across asia it is a version of 'cha' (i.e. 'chai' in india), and then in europe it ranges from te´ to the´ to tea, with the occasional cha thrown in for good measure.
Tea in japanese is (o-)cha too. In the 16. Century the whole world (europe excluded) was seperated in a spanish and a portugues part. Japan and everything eastwards became potugues terrain.
In Japan the word for bread is also pan.
