ハチ公像設置100周年を記念し、参加者自身がハチ公となって渋谷の街を歩き、点在する飼い主を探す都市型ARG（代替現実ゲーム）。渋谷ハチ公前広場を舞台に実施した。
問い：「待つ」「探す」という行為を、ハチ公を通じて再考する。
ハチ公像設置100年史を調査し、ハチ公の眼差しから撮られた写真のみを収集して、ハチ公像から見た渋谷の都市変遷を読み解いた。「待つ」「探す」行動がSNS時代にどう変容しているかを考察し、参加者自身がハチ公の立場になり、主人を探す体験を設計した。
参加者はしっぽ型キーホルダーを受け取ってハチ公になり、渋谷の街中に点在するヒントをたどりながら飼い主を探す。発見すると報酬カードを獲得し、ハチ公が待ち続ける中で見てきた渋谷の風景を追体験する。
しっぽ型キーホルダー、QRカード、街歩き用MAP、立て看板など、参加体験を支える配布物も設計・制作。渋谷区・所轄警察署・SCT実行委員会と折衝し、道路使用許可の取得から配布物の運用ルール設計まで行った。

Held at Hachiko Square and other locations in Shibuya, October 2025 – February 2026, as part of DIG SHIBUYA 2026. Co-planned with YUKI MORITA.
To mark the 100th anniversary of the Hachiko statue, this urban ARG (alternate reality game) invites participants to become Hachiko themselves and walk the streets of Shibuya in search of owners scattered across the city. It was staged at Hachiko Square in Shibuya.
Question: How can the acts of "waiting" and "searching" be reconsidered through Hachiko?
The artist researched the 100-year history of the Hachiko statue, collecting only photographs taken from Hachiko's point of view to trace how Shibuya has changed as seen from the statue. Considering how waiting and searching have changed in the age of social media, the experience was designed so that participants take Hachiko's place and search for their master.
Participants receive a tail-shaped key chain and become Hachiko, following clues scattered around Shibuya to find the owner. Those who find them receive a reward card and relive the Shibuya scenery that Hachiko saw while waiting.
Handouts supporting the experience were also designed and produced, including the tail key chains, QR cards, a walking map and signboards. The project involved negotiations with Shibuya City, the local police and the SCT executive committee, from obtaining road-use permits to designing rules for the handouts.
