We spoke with Mr. Satoshi Ota, CEO of Office Mook Co., Ltd., which provides management direction consulting—including web and system development—for food and beverage companies, advertising agencies, newspapers, and more, about why they introduced Repsona and how it’s working for them.

What kind of work do you use Repsona for?

Mr. Ota:
Office Mook Co., Ltd. mainly provides system development and web direction services, along with marketing and promotional support.

In addition to development and production, we receive many IT-related consultations and requests—such as distributing online ads, listing advertisements, and managing social media campaigns—which we handle in collaboration with external partner companies.

Since there are many players involved both inside and outside the company, we use Repsona to manage tasks and monitor project progress across all stakeholders.

What challenges did you face before using Repsona?

Mr. Ota:
I’ve always liked task management tools, so I’ve tried many of them—but often ended up abandoning them.

I used Asana quite a while ago but stopped using it soon after. I also tried Trello, but since the Gantt Chart (Timeline) required a plugin, it didn’t quite fit my ideal workflow.
I experimented with managing projects on GitHub, but it’s really geared toward engineers—making it hard for non-engineering members like directors to use effectively.
I also used Backlog and Redmine, but since our projects aren’t large-scale system developments, those tools felt a bit too heavy and not quite the right fit.

Functionally “just right.”

Why did you choose Repsona?

Mr. Ota:
Repsona feels functionally just right. Once you create a space, you can immediately start using the Gantt chart (Timeline) and easily switch to the Kanban view. The ability to quickly create parent-child relationships between tasks is also a huge plus.

While dedicated project management tools are convenient, they often require team members to go through a steep learning curve. Many freemium tools also restrict key features—like Gantt charts—to paid plans.

Repsona, on the other hand, offers full functionality at a low cost, so I upgraded to the paid plan right away.
It also runs very smoothly and feels lightweight—which is extremely important. And I have to say, the dark mode is fantastic. I’m very satisfied overall—it’s simple, efficient, and pleasant to use.

Tasks can also be checked in Kanban view.

Dark mode looks great and is comfortable to use.

What do you expect from Repsona in the future?

Mr. Ota:
I’m very satisfied, so there’s nothing I urgently want at the moment. But if I were to make one suggestion, I think it would be even more convenient if Repsona could integrate with other systems via an API.

It would be exciting to see Repsona’s ecosystem expand through open API connections.
