01 From the Edo to Meiji Periods: Mitsui Paved the Way for Settling the Land

The Shimosa Plateau, now home to Kashiwa-no-ha, was a famous horse-breeding area from early times. Throughout the Edo era (1603 to 1867), the horse paddocks were directly under the control of the Tokugawa Shogunate. Kashiwa-no-ha once belonged to a paddock named Koganemaki.

Upon the Meiji Restoration, the government abolished Koganemaki and promoted settlement and agriculture there. The central figure in that endeavor was Mitsui Hachiroemon Takayoshi the eighth head of the Mitsui clan. He became president of a land reclamation company and supported the area by building schools and shrines and undertaking other development. Chiba Prefecture thereafter named each reclaimed property according to when groups settled, adding numerical suffixes to location names. Kashiwa City still retains some of that nomenclature, examples being Toyoshiki to convey being “fourth” and Toyofuta to indicate “12th”.

Takayoshi Mitsui

The eighth head of the Mitsui clan worked after the Edo era on reforms to the domestic economy, which had encountered financial difficulties after the Tempo period (1830 to 1844). He overcame great political difficulties during the transition to the Meiji Restoration to launch Mitsui Bank and Mitsui & Co., which became foundations for the Mitsui financial clique. He also exerted himself in public businesses, leading cultivation at Koganemaki.

02 Showa Era: A New Page in History for Mitsui Fudosan and Kashiwa-no-ha

After the Korean War erupted, the United States Air Force built a communications base on 188 hectares, around where the current campus of The University of Tokyo, Chiba University and Chiba Prefecture's Kashiwa-no-ha Park are located. In 1961, Mitsui Fudosan opened Kashiwa Golf Club. The Japanese economy was booming at the time. For 40 years until the club closed in 2001, numerous golfers loved this prestigious facility. In 1979, when the United States Air Force returned the entire property, the area made a fresh start as a new town.

03 Heisei Era: New Towns Launched after Land Readjustment

In 2001, Kashiwa City began a Land Readjustment Project based on an urban planning project at the 273-hectare Kashiwa-no-ha area. In 2005, the Tsukuba Express began operating and Kashiwa-no-ha Campus Station was built. The convenient access ushered in a new period for Kashiwa-no-ha.
