Together with his father, Junzo SHibata, Shibata Takenaka and his younger brother Nagamochi Kohjiro distinguished themselves in academics and in martial arts.

In 1858 Shibata became chief of staff in the gaikoku bugyo (foreign affairs department).

Nagamochi Kohjiro was transferred to work in Nagasaki Bugyohsho (Nagasaki Magistrate's office) to help Shibata with his work.

His first visit to Europe was in 1862 as one of the principal members of the First Japanese Embassy to Europe .
His nephew Nagamochi Goroji accompanied Shibata to Europe as his retainer.

During the 1862 mission, Shibata Sadataro Takenaka was chief of staff and first secretary. 
In fact, Shibata was one of the heads of the mission and participated directly in the negotiations, but he did not express himself, he was there as an observer, he listened and took notes. On his return to Japan, he was to report on the progress of the mission and the behaviors of the negotiators. In fact, he was the key person for intelligence gathering in Europe. The newspapers of the time nicknamed him "the shadow".

In 1863, he became gaikoku bugyo (commissioner of foreign affairs). His first assignment was to go to Hakodate to negotiate with a Russian consul general Iosif Antonovich Goskevich regarding the opening of Japanese ports.

In 1865, Shibata Mission was dispatched to Europe. Shibata stationing in Paris for a year, requested that both the United Kingdom and France send a military mission for training in Western warfare on behalf of the Tokugawa shogunate. The UK declined, but the French accepted. This led to the first French military mission to Japan from 1867 to 1868, which Shibata organized.

He became in charge of the opening of the Port of Kobe, and had piers, residential areas for foreigners, and Tokugawa-do (Tokugawa Road) constructed.

In 1868, he declared the Port of Kobe open to the world in front of foreign delegations.

After the Meiji Restoration, he declined the offer from the Meiji Government to work for them.
After his retirement, whenever the Meiji Government requested his advice, he answered them sincerely.

Ancestral background 
The ancestor of the Shibatas was an Igamono Shinobisamurai, Shibata Suwo.

In 1582 by the request of Hattori Hanzo, Shibata Suwo with his relative Nagamochi Tokuzo escorted Tokugawa Ieyasu in the Shinkun Iga Passing after Honnoji Incident and both were officially taken in to serve the Tokugawas. They moved to Edo in 1590 following Tokugawa Ieyasu. They became Iga Dohshin Hiroshikiban (Igamono police to serve in the shogun's private quarters in Edo Castle while engaging in shinobi missions from time to time).

Under the 10th shogun, Shibata Jinshiro was transferred to work in the shogunate's Gakumonsho (shogunate university).  Under the 11th shogun, Shibata Junzo became Metsuke.

After the Iga Passing Incident in 1592, the Shibatas and the Nagamochis kept tight-knit as one clan. By the Bakumatsu period they also formed strong relations with the Oniwaban families through marriages.
