Earlier this year while in Japan, I bought a historical fiction novel, Tenyuu wa Nobunaga ni ari (Heavenly Blessings are in Hands of Nobunaga) by Iwamuro Shinobu. The novel series is in three volumes. I have the first two and currently reading the second volume regarding to the Battle of Okehazama. The second volume goes into great depth into the meeting between Nobunaga and Dosan, Battle of Muraki, Kiyosu, assassination of Nobuyuki, Battle of Nagaragawa, Nobunaga's trip to Kyoto, unification of Owari, and Okehazama. I am extremely enjoying reading the novel so far. Highly recommend it for a spring or summer reading.
Tenka no tame!
