道の駅舞ロードIC千代田トイレにおいて利用実態調査をもとにリノベーションを計画し，工事後に計画内容の適性ついてアンケート調査の結果を比較して検証した．工事後は良い印象の回答数が増加するとともに，より多種の形容詞を用いて回答され，多様な利用の可能性も観察された．便房内の装飾を検討・制作するワークショップにおいては，参加者がワークショップで実施した何によって満足を得たのかが明らかになり，実施内容に対して一程度の習熟がえられていることがわかった．

The renovation was planned based on the survey of actual usage at Michinoeki Mai Road IC Chiyoda. After completion of construction, the appropriateness of the renovation plan was verified by a questionnaire survey. Compared with before the renovation, the number of responses that showed a good impression after the renovation increased by 25%, and the possibility of various uses was observed. At the workshop phase of decorations in the toilet booth, most of the participants were satisfied with the work. In addition a text mining of the reasons for satisfaction shows that they were satisfied and understood the intent of the work, which suggests that the workshop was of appropriate content and difficulty.
