Our Message

“From being a country known for longevity, to a country known worldwide for long, healthy lives.”

I hope this email finds you in good health.
We thank you for your continued support.

Our mission at MRSO Inc. is to increase the amount of healthy hours (healthy life expectancy) in an individual’s life.

In Japan, the average lifespan for males is 80.21 years and for females 86.61 years. However, the healthy lifespan for males is only 71.19 years and for females 74.21 years. *Based on the Ministry of Health, Labor and Welfare’s Data for 2013.

The Japanese are well-known for their longevity. However, within their lifetimes, there is a 9-12 year period during which their lifestyles are severely limited. Through our activities, we aim to extend healthy lifespans by 8 years, creating a society where people can live long, rich lives.

For that purpose, we are working hard to develop preventative medical healthcare, including checkups, proper exercise, nutrition and mental care. Using the power of IT, we can provide you with information relating to medical services, helping you to choose a suitable facility and make a reservation.

We want to thank the various users, medical facilities and related organizations for their support, which has allowed us to grow and make progress towards our very significant goal of extending healthy life expectancy.

MRSO Inc. would like to explore new possibilities in the medical and IT fields. We will do our best to create a future filled with hope, by changing Japan from being a country known for longevity, to a country known worldwide for long, healthy lives.
