It is the year 1988. Yamabuki is an eight-year-old little boy growing up in a traditional family where every family member has problems and secrets they try to hide from each other. The father runs a failing construction company and has an intimate relationship with another woman. The mother is struggling with severe depression, as she cannot cope with the death of her youngest child. The grandfather, who used to be a construction engineer, hopes to start building an amusement park, but to no avail. The grandmother runs a small store where she sells items of forged origin. The sister is fed up with the lies of her predecessors and is looking for a way to run away from home. In the midst of all this chaos, Yamabuki has started to find solace in patting an imaginary dog.

本作品在宫泽贤治一生9次进京中，着眼于其中成为转折点的4次：与父亲的对峙，对妹妹的爱，信仰与农民运动，还有宫泽贤治在心中描绘的伊哈托布（理想乡）。在摇摇晃晃的夜行列车上，目的地是岩手还是东京，抑或是群星闪耀的宇宙尽头？

詩人にして童話作家、宗教家で音楽家、科学者で農業技師、土壌改良家で造園技師、教師で社会運動家。しなやかで堅固な信念を持ち、夭逝した宮沢賢治。短い生涯でトランク一杯に挫折と希望を詰め込んで、岩手から東京に上京すること九回。そのうち転機となった四回の上京を、あの世に旅立つ亡霊たちや自ら描いた童話の世界の住人と共に、夜汽車に揺られてダダスコダ、ダダスコダ。行きつく先は岩手か東京か、星々が煌めく宇宙の果てか…。
「世界がぜんたい幸福にならないうちは、個人の幸福はありえない」
そう信じた宮沢賢治が夢見たイーハトーボは果てしなく遠かった。
（2019年2月5日～24日 紀伊國屋ホール）

A recently widowed writer whose wife died in a bus crash comes to terms with his grief—or lack of it—in caring for the children of a working man who also lost his wife in the same accident.

Death-row inmate Sudo sends a letter to magazine reporter Fujii. In his letter, he states that a man named Kimura, also known as "teacher," committed numerous murders for insurance money. While checking out the story, based on Sudo's tip, Fuji becomes convinced that the letter is correct. But, a lot of time has passed from the incidents and Sudo's testimony isn't clear. Due to the persistance of Sudo, who is a former yakuza, and Fuji, the police begin to move.
