In the Introduction to his charming Tales of Old Japan, Mr. Mitford wrote in 1871:
'The books which have been written of late years about Japan have either been compiled from official records, or have contained the sketchy impressions of passing travellers. Of the inner life of the Japanese the world at large knows but little: their religion, their superstitions, their ways of thought, the hidden springs by which they move - all these are as yet mysteries.'
