Yoritomo Watanabe

Please note: This article is about the Watanabe family Founder. For other uses of the term, please see Watanabe (disambiguation).
Watanabe served Yoritomo by building ships for the Mantis Clan. The ships were innovations over other kobune of the time and were considered a water tight box. Way of the Minor Clan, p. 15
== Sengokobune ==
At the end of the 11th century, Watanabe created the sengokobune, which overshadowed the kobune in size, speed, and reliability. Book of Water, p. 116 His design had an outward appearance close enough to the kobune, to circumvent the Imperial Decree that forbade ocean-going ships. Emerald Empire; Fourth Edition, p. 135
== Vassal family ==
After the ascension of the Mantis as a Great Clan he was named Yoritomo Watanabe, and he was the founder of the Watanabe family patroned by his Champion, Yoritomo Aramasu. Secrets of the Mantis, p. 29
== Demeanor ==
Watanabe was not a very good leader, just a fine shipbuilder. Aramasu chose several aides for Watan­abe to manage the family. Among them came the finest shipbuilders in the clan who swore fealty to the fledging family. 
== Death ==
Watanabe died two years after the founding of his family.
