Note 6 — Chapter XII · EXILE AT SUMA
Arthur Waley translation
The distance is about 60 miles. It could, says Moto-ori, in no circumstances have been covered in one day. He therefore concludes that the travellers spent a night at Naniwa (the modern Ōsaka) on the way. A much more probable solution is that Murasaki was herself rather vague about the time which such a journey would take.
