His father was from Kagoshima Prefecture and was a government employee who moved to Tokyo when he entered university, and his mother was a liberal-minded person.

After graduating from Koshigaya Kita High School,[3] Furuichi entered the Faculty of Environment and Information Studies at Keio University in 2003.

Furuichi said he studied abroad to escape from job hunting and went to Norway with a vague image of a country with high welfare and happiness.

[8] A contributor to various literary magazines, Furuichi critiqued the arbitrariness of institutionalized job-seeking practices that university students are expected to engage in, demonstrating the severe dilemmas of "most-popular employer" rankings (which seem to predict future company performance only very poorly; see Shincho 9/2012).

[8] Furuichi’s books since 2012 include Nobody Can Teach War (Kodansha, 2015), That’s Why Japan is Off Track (Shinchosha, 2014) and Making Nursery Schools Compulsory (Shogakukan, 2015).

"[11][12] In many of the programs in which Furuichi appears, the host first asks him to comment on a hot news topic, and when he makes a controversial statement, a heated debate often ensues.
