I found some information on the Battle of Terabe in 1558. In A.L. Sadler's book, The Maker of Modern Japan, the lord of Terabe was Suzuki Shigeteru (Sadler, p.51). However, Owada Tetsuo's Okehazama no Tatakai, the lord of Terabe was Suzuki Hyuga no Kami, Shigetoki (Owada, pp. 104-105). Owada rarely fumbles so I presume the name was Shigetoki.
This was Tokugawa Ieyasu's first baptism of fire and it was successful. I did manage to add the information in the 2nd edition to the Okehazama book as well. The battle started when the lord of Terabe switched sides and became an ally for the Oda.
Terabe is located in Aichi Prefecture. Toyota-shi, Terabe-cho.
As for the Battle of Terabe, it was many of the endless conflicts that led to the Battle of Okehazama in 1560.
