[The JapaneseJ are so crafty in their hearts that nobody can understand them. Whence it is said that they have three hearts: a false one in their mouths for all the world to see, another within their breasts only for their friends, and the third in the depths of their hearts, reserved for themselves alone and never manifested to anybody. As a result all order decays here for everyone acts merely according to the present moment and speaks according to the circumstances and occasion. But they do not use this double dealing to cheat people in business matters, as do the Chinese in their transactions and thieving, for in this respect the Japanese are most exact; but they reserve their treachery for affairs of diplomacy and war in order not to be deceived themselves. And in particular when they wish to kill a person by treachery (a strategem often employed to avoid many deaths), they put on a great pretence by entertaining him with every sign of love and joy-and then in the middle of it all, off comes his head.
[The] first bad quality [of the Japanese} is that they are much addicted to sensual vices and sins, a thing which has always been true of pagans. The men do not pay much attention to what their wives do in this respect because they trust them exceedingly, but both husbands and relatives may kill an adulterous wife and her partner at will. But even worse is their great dissipation in the sin that does not bear mentioning This is regarded so lightly that both the boys and the men who consort with them brag and talk about it openly without trying to cover the matter up. This is because the bonzes [Mahayana Buddhist monk] teach that not only is it not a sin but that it is even something quite natural and virtuous and as such the bonzes to a certain extent reserve this practice for themselves. They are forbidden under grave penalties by ancient laws and customs to have the use of women and so they find a remedy for their disorderly appetites by preaching this pernicious doctrine to the blind pagans. They are certainly past masters in this teaching and so they are worse and more openly involved in it than other people. But their great influence over the people, coupled with the customs handed down by their forefathers, completely blinds the Japanese, who consequently do not realise how abominable and wicked is this sin, as reason itself plainly shows. ...
They also have rites and ceremonies so different from those of all the other nations that it seems they deliberately try to be unlike any other people. The things which they do in this respect are beyond imagining and it may truly be said that Japan is a world the reverse of Europe; everything is so different and opposite that they are like us in practically nothing. So great is the difference in their food, clothing, honours, ceremonies, language, management of the household, in their way of negotiating, sitting, building, curing the wounded and sick, teaching and bringing up children, and in everything else, that it can be neither described nor understood. . . .
Although [the Japanese] make use of pitch, neither going up nor down, their natural and artificial music is so dissonant and harsh to our ears that it is quite a trial to listen to it for a quarter of an hour; but to please the Japanese we are obliged to listen to it for many hours. They themselves like it so much that they do not think there is anything to equal it in the wide world, and although our music is melodious, it is regarded by them with repugnance. They put on many plays and dramas about various wholesome and joyful things during their festivals, but they are always accompanied by this music.
