Our Mission is to create a world where medical services can be accessed with technology anywhere, anytime.


The five work values embraced by Medmain.

Memain Images

Think deeply
and strategically.

We discover and implement the most substantive method to achieve goals by taking a multifaceted and panoramic viewpoint.

Memain Images

Opt for a path that has
a greater impact.

As it is said that humans make 9,000 decisions per day, we provide greater efficacy and value to these daily decisions, and achieve goals by selecting that which has the greatest impact.

Memain Images

Moving ahead
while maintaining
high quality and speed.

We do not produce unpolished, low-quality output, and we avoid reductions in speed resulting from getting bogged down in non-essential details. We proceed with a balance between sufficiently high quality and satisfactory speed.

Memain Images

Have an open
and respectful mind.

We strive for open communication and are ready to accept diverse opinions. We create a friendly environment in which everyone can work comfortably with respect for the opinions, work and personalities of other members.

Memain Images

Treasure positivity
and creativity.

At all times, we foster a spirit of autonomy as well as behaviors that engage others, and we respect innovative ideas.
