When I heard from my director about this project. The client said that they will make a facility with a pool and an onsen, and then, they want a logo mark which is cool thing. At that time, these things were provided from my director.
First of all, I got some hint from keywords which are an onsen and colors, such as Akita prefecture, waterfalls, Blue and Green from picture and of course Onsen. then, I suggested 3 type of logo which are a modern version, a calm version, and a typical Onsen version. I prepared some mockups which are Glass Door Logo Mockup and Indoor Signage Mockup for easy to image real store. then, the client and directer satisfied my suggestion.
