We’ve rounded up the handy tools our technical directors have made

We’ve rounded up the tools our technical directors, Umetsu and Okabe, have made so far.
Beyond introducing Chrome extensions you can use too, we also look back on tools developed within past projects — please take a look.

Handy tools everyone can use

Here’s a roundup of the Chrome extensions and other tools that TD Okabe has made and released. You can use them too, so we’d be glad if you put them to work.

■ Chrome extensions

1. crawl sitemap generator

A Chrome extension that makes it easy to generate a sitemap. It crawls the site you’re viewing and outputs a list of its pages. Paste the output into a spreadsheet or Excel, and you can build a sitemap quickly and easily.

2. Capture Assist

A tool to assist with capturing sites. Its auto-scroll, with customizable speed and easing, is handy. You can also choose to show or hide the cursor, so it’s very useful when capturing a site. We use it in video production, starting with the introduction videos we make when a site launches.

3. gyazooo

An extension that adds the following feature to the online screenshot service gyazo: it skips the page shown after you capture and displays the image URL directly. When sharing, sending the image URL directly — rather than the gyazo page URL — shortens the time to display and is appreciated.

4. Environment-info tool (https://env.mount.jp)

Environment info you can check just by opening the page.

A handy tool that lets you easily grasp the environment info of a client or team member. Instead of “tell me your OS/browser,” you can say “copy and paste the results from this URL” and comprehensively grasp the other person’s environment.

A roundup of tools developed in past projects

At our company, the TDs often develop dedicated tools needed for each project. We’ve looked back on the dedicated tools we’ve introduced in the past — please take a look.

1. Yamauchi No.10 Family Office (Dev: Umetsu)

A dedicated modeling tool and object-placement tool developed for building the Yamauchi No.10 Family Office site. On this project, we created 274 kinds of objects in total and laid them out on the stage using the object-placement tool.

▼ Modeling tool
We built objects by stacking pixels one by one while viewing each face, moving back and forth between screens showing the side, top, front, and 3D views. We then adjusted the pixels frame by frame on the finished objects to animate them.

▼ Object-placement tool
We placed the finished objects one by one. Considering the overall flow and the sense of scale of each object, we composed layouts for PC and SP separately.

2. PERFECT DAYS (Dev: Okabe)

For the PERFECT DAYS site, we made three dedicated tools — tools indispensable for expressing the film’s world view on the site.

▼ Typography tool
The strokes traced with the dedicated tool are saved as color information — red = start point, green = end point — and turned into a sprite sheet, recording the outline and stroke information of every character in a single image. With this tool, we achieved the effect of a novel’s characters being drawn in the correct stroke order and coming apart one stroke at a time.


▼ Mixer tool
We made a tool to set the linkage between text and sound, and finely tuned it together with musician Reo Sato. As a result, 117 ambient sounds are mixed in naturally according to your position in the novel you’re reading. (In some scenes, more than 10 tracks overlap.)


▼ Kerning tool
We developed a tool for kerning implemented pages directly in the browser. It operates with the same shortcuts as Adobe Illustrator and allows several people to work at once. On the PERFECT DAYS site, we finely adjusted not only headings and UI but the body text as well.
This tool has been useful in other projects too, and we used it to kern the AYANA BALI site.

3. AYANA BALI (Dev: Okabe)

For the AYANA BALI site, we developed tools to efficiently manage an enormous amount of content — over 800 pages across four languages.

▼ Spreadsheet CMS
We developed a CMS that generates pages from Google Sheets/Drive. All text and images can be managed in a spreadsheet, and on top of the familiar usability, it makes full use of the sheet’s native features — simultaneous multi-user editing, cell-level comments, edit history, and more.

A proprietary CMS that generates pages from a spreadsheet.


▼ Bulk image-replacement tool
To efficiently reflect the roughly 1,200 images used on the website into the CMS, we developed a Figma plugin. Where you’d normally replace every image one by one, this handy tool replaces them all at once with a single button. It’s been updated so it can be used generically on other projects, and has become a tool that sees heavy use in-house.

◉ Plugin features
Bulk-replace before/after retouched images by matching file names
Bulk-generate export frames from the design data
- Fixing the issue of frame sizes ending up as decimals by rounding to integers
- Adding extra margin for parallax
- Automatically setting the export scale according to where the image is used and the device

4. KUBOTA FUTURE CUBE (Dev: Okabe)

For the KUBOTA FUTURE CUBE site, we developed a dedicated tool to realize its distinctive 3D space.

▼ Cube-creation tool
A tool that lets you place finely parted-out illustrations in 3D space to build a cube. You can try the tool via the link below. Saving is disabled, so feel free to play around however you like.

*Operating from a PC is recommended.

◉ Controls
Basic cube shortcuts
- wheel → zoom
- drag → orbit the camera
- shift + drag → pan
- shift + 0 → reset camera
- shift + alt + drag → move horizontally and vertically
Shortcuts on the in-cube mesh-creation screen
- hold shift and select vertices → multi-select
- select an edge and cmd + click to add a vertex
- hold alt and click a vertex → delete

Wrap-up

This time, we rounded up the handy tools our technical directors have developed. Those wonderfully thoughtful, itch-scratching Chrome extensions are used by almost everyone in the office. There’s no set plan for future releases, but personally I’m hoping more efficiency-boosting tools get made. And the dedicated tools developed on past projects each offer a glimpse of the trial and error in our production process. I’m really looking forward to seeing what tools are born in future projects.

Our goal isn't to make things for our own sake — it's to solve problems. We'd love to hear what's on your mind.
