Hoshino travels frequently and has participated in writers' caravans with authors from Taiwan, India, and elsewhere. In 2006, his critique of Ichiro Suzuki's remarks at the World Baseball Classic were considered controversial by some, and so have some of his other writings related to Japanese nationalism, the emperor, sexuality, bullying, and Japanese society. Also in 2006, the literary journal Bungei dedicated a special issue to Hoshino and his work. He teaches creative writing at Waseda, his alma mater. In January 2007, he was nominated again for the Akutagawa Prize, this time for Shokubutsu shindanshitsu .* In 2011, Hoshino won the Kenzaburō Ōe Prize for his novel Ore Ore, which explores the meaning of identity in the postmodern world. The title takes its name from the first-person Japanese pronounore. Early in the novel, the narrator engages in a kind of scam known in Japan as a ore-ore sagi, in which he calls up an older person, pretends to be a relative, and tries to get the person on the other end of the phone line to send money. In the novel, the narrator finds himself unwittingly pulled into the life of the person whose identity he has fraudulently assumed, at the same time that someone else assumes his identity. This starts a chain-reaction of identity-stealing that extends to the edges of society, creating an increasingly surreal and dangerous world in which no one is exactly who they seem. The novel has been translated as ME by Charles De Wolf for Akashic Books. In 2014 Hoshino won the Yomiuri Prize for , a novel based on One Thousand and One Nights that shifts narrative voice to misdirect the reader. In 2018 he won the Tanizaki Prize for.
