The Sora Tabi Nikki (曾良旅日記; 'Travel Diary of Sora') was the memorandum of Kawai Sora in 1689 and 1691 when he accompanied Matsuo Bashō on the journeys recounted in Oku no Hosomichi, for which it has become an important study tool. By the time it was re-discovered in 1943, the presence of this diary had been doubted.
The diary The existence of this diary had been known and it was re-discovered and published by Yasusaburo Yamamoto in 1943. It was designated an Important Cultural Property of Japan on June 15, 1978. The diary was 11 cm in length, 16.5 cm in width and 2 cm in thickness; the book cover was indigo and the volume contained 100 sheets of paper, including 4 white sheets. There were 11 sheets of paper pasted. For convenience, it has been divided into parts: Summary of Divine Names of Engishiki, Memorandum of Utamakura, Diary of Genroku 2nd year, Diary of Genroku 4th year, Memorandum of Haiku and Others. Inside the diary, there were no such divisions. The diary was called also Sora Nikki (Sora Diary) and Zuiko Nikki (Diary of Sora accompanying Basho). In the diary, there were no emotional sentences such as seen in Oku no Hosomichi. The names of lands visited and the distances between places were recorded precisely. Donald Keene compared this diary to the diary of François-René de Chateaubriand, namely exactly recording the data of the trip by Julian who accompanied his master. The recording of time in the middle of Edo era in this diary is noted as most exact one. It was shown in Earthly Branches and the time was shown in three divisions. He wrote that while they worshiped at shrines or prayed before shrines, they only visited or saw temples, indicating that he was an earnest Shintoist.
Engishiki Shinmeicho (List of kami) Engishiki: This was a list of kami by Sora, who studied Shinto under Yoshikawa Koretari (1616–1695) in preparation for their travels. It occupies the beginning of the diary, up to the halfway point of the 12th sheet of paper. Utamakura memorandum In preparation for the trip, he wrote an utamakura memorandum based on the Ruiji Meisho Wakashū and Narayama Shūyō. It consumes 8 sheets, starting on the back of the 12th sheet. Findings in the trip were added between the lines. One sheet of paper was pasted. This is also called the "Meishō Memorandum". 1689 diary

Between these two events, Sora recorded everything in the journey, including the real dates, weather, schedule, and stays in inns. This has become an important document for the study of Oku no Hosomichi. On September 3, Sora rejoined Basho at Ogaki, and the two returned to Fukagawa on November 13. Sora recorded details of the trip. 1691 diary Sora started on March 4, 1691 and arrived at Nagashima on July 25. This diary is also called the Kinki Area Journey Diary.

Kumano, Wakaura, Suma, Akashi. He recorded the shrines and temples and Utamakura. He visited Basho who was staying at Sagaraku Kakisha, and recorded Basho and his disciples who were editing Sarumino. Haikai Kakidome Haikai Kakidome recorded the hokku (starting verse of a renku) and haikus of Basho and Sora during their journey and the haiku meetings during their journey.

Zatsuroku (trivia) On the Japanese archery, anecdotes on Teishitsu which Sora recorded at Yamanaka Spa, names and addresses of persons Sora and Basho met on their journeys, old haikus; these were jotted down.
History prior to rediscovery The original book had been present together with a copied manuscript of Oku no Hosomichi called Sora Hon in the same box made of paulownia wood. This book was in the hand of Sugiyama Sanpū who was a close friend of Sora when Sora died in Iki Island, now Nagasaki Prefecture. Shikōbō Hakushū, who was a brother-in-law of Sansha, a son of Sugiyama Sanpū, wrote that Sanpū possessed this book. This book was sent to Takano Family where Sora was born. When the Takano Family ended, this book was under the control of Kasai Family, who was the family of the mother of Sora. Kasai Shūtoku, of the Kasai Family, was married with the daughter of one elder sister of Sora. He respected Sora. He edited a book Yukimaruke concerning Sora from various documents of Sora. Later the book went to Kubojima Wakōdo. Chikurinsha Atsujin of Sendai wrote Wakōdo had originally retained the Diary of Sora.Roinsha Chikusai wrote in his book the map of Sendai in Sora's diary and a line of July 20, 1689 were transcribed at the Wakodo's house. According to a Journal of History of Suwa in 1967, the diary of Sora was illegally taken away from the Kasai Family. Namely Wakōdo defrauded the Kasai Family of Sora's diary. Wakōdo bought 8 items of Kasai Family including the diary at 58 ryō Tael but paid only 10 ryō. Wakōdo was punished by the Takashima han, but the diary was not returned. On the original box, there was a formal letter of transfer of the original Okuno Hosomichi and Sora's diary by the name of Wakōdo. Later Matsudaira Shimanokami, one of the daimyō, bought the box. Honma Keishi attested to it. On the Sora's diary, fragments of documents were occasionally seen. For instance, Yawatei Ukō wrote the summary of the Diary from April 21 at Shirakawa to May 9 at Matsushima in Aokage Shū. Asukaen Issō wrote the summary from the start to May 17 at Obanazawa.
