Starting a side business with yakuzen: the road from no experience to income

Yakuzen brings the wisdom of Chinese medicine into daily life. This old and new wisdom about food is now opening up possibilities as a side business.

Yakuzen is often thought to need special ingredients, but what makes vegetable yakuzen appealing is that you can practise it with everyday vegetables and fruit. Being able to propose eating matched to constitution, how someone feels and the season, using supermarket ingredients, means demand for people with the knowledge is rising.

What makes yakuzen appealing as a side business is putting your own health knowledge to work while being useful to people. Above all, you can start without special equipment or a large initial investment.

Even with no experience, the right knowledge and a little thought can turn into income.

Five side-business models for earning from what you know of yakuzen

There are many forms a yakuzen side business can take. Being able to choose to suit your skills and your taste is part of the appeal.

The first is running an online course. A course teaching the basics of yakuzen and seasonal recipes can be run from anywhere. Made into video content, it can be sold again and again once made.

Next comes recipe development and supervision. Working with restaurants and manufacturers to develop and supervise menus and recipes built on yakuzen earns income. Someone I know developed a yakuzen bread with a local bakery and it went down very well.

Yakuzen counselling is another popular form. It offers eating advice matched to a person's constitution and how they feel, and can be done online or in person. As people grow more health-conscious, demand for personalised advice about food is rising.

Running a yakuzen cookery class is another standard route. It can be run for small groups in your own kitchen or in a rented space. Setting a theme for each season also brings people back.

Last comes making yakuzen content. Publishing about yakuzen on a blog or social media and earning through advertising, affiliate links or e-book sales. It calls for publishing steadily, but the appeal is that you work at your own pace.

Which form do you think suits you?

From qualification to starting a yakuzen side business

If you want yakuzen as a side business, start with a qualification to build both knowledge and credibility.

There are in fact a great many yakuzen-related qualifications. Typical ones include Kokusai Yakuzenshi, Yakuzen Meister (Wakan Yakuzenshi) and Yakuzen Coordinator.

Correspondence courses are a popular route. A course such as the Yakuzen Meister training can be taken at home at your own pace, which fits alongside a main job. Fees start from around 40,000 yen and courses run about four months, though some finish in around two.

After qualifying, the trick is to start small. Offer yakuzen advice or a simple session free to friends and family. Build a track record and some confidence, then move gradually to paid services.

Publishing on social media works well too. Sharing yakuzen information and what you are doing on Instagram, note or Twitter creates points of contact with potential customers.

What it takes to make a yakuzen side business work

A few things matter in making yakuzen work as a side business.

First, standing out. Yakuzen is broad, so find the field and the angle that are yours. Narrowing your audience, to yakuzen for working women or yakuzen for parents of young children, makes the value clear.

Next, learning continuously. Knowledge of Chinese medicine and of nutrition has to be kept up to date. Bringing in the latest findings raises the value of what you offer.

Building a network matters too. Connections with specialists in the same field and in related areas of health create chances to work together and to be recommended. Try yakuzen seminars and communities on social media.

Making your track record visible should not be forgotten either. Gathering what customers say and cases that went well, and sharing them on social media and a blog, builds credibility. Do it with proper care for personal information, of course.

Finally, balance with your main job. As a side business, pacing it so it does not get in the way of the main job matters. Plan it within what you can keep up without strain.

What a yakuzen side business earns, in real numbers

You will want to know how much a yakuzen side business can earn. Here are the models and the figures.

For an online course, fees of around 3,000 to 10,000 yen a session are usual. Two sessions a month with five people each means 30,000 to 100,000 yen a month. Made into video content, it can go on selling.

For a yakuzen cookery class, around 5,000 to 10,000 yen a session is the going rate. With ten people a session, after ingredient costs you can expect around 20,000 to 40,000 yen from one session. Even once or twice a month makes a steady second income.

Recipe development and supervision varies greatly by project, but around 20,000 to 100,000 yen a job is usual. Higher-rate work that draws on real expertise, such as menu development for restaurants or recipe supervision for food manufacturers, is possible.

Making yakuzen content earns through advertising on a blog or social media, affiliate links and e-book sales. Income builds up over time; small at first, it can reach a steady tens of thousands of yen a month if you keep going.

As a side business, aiming at around 50,000 yen a month is realistic. Start at a pace you can keep up alongside your main job.

What to watch for, and the legal side

There are things to watch for, and legal points to consider, when starting yakuzen as a side business. Keep them firmly in mind to avoid trouble.

First, the line with medical practice. Yakuzen is advice about food, not a medical act. Avoid presenting it as treatment for illness or a substitute for medicine, and hold to the position of supporting health through food.

How you describe effects matters too. Definite claims such as curing a named illness, or working on a named condition, may fall foul of the Pharmaceuticals and Medical Devices Act. Keep to measured wording: that an ingredient warms the body, or that it has traditionally been said to do something.

How it sits with your main job matters as well. If you are an employee, check that your terms of employment do not prohibit side work. More companies allow it as of 2025, but checking first is essential.

Do not forget your tax return either. Side-business income over 200,000 yen a year requires a return. Some costs count as expenses, so keep your receipts.

Handling personal information deserves care too. Personal information obtained through counselling or an online course has to be managed properly, with a clear privacy policy.

Keep these in mind and you can start a yakuzen side business with confidence.

A real example, and what made it work

Let us look for what makes it work in the experience of people running a successful yakuzen side business.

Someone I know earned the Kokusai Yakuzenshi qualification and started by publishing seasonal yakuzen recipes on Instagram. Concentrating on quick, easy recipes using supermarket vegetables rather than special ingredients won her a following among busy homemakers.

After about six months of publishing steadily, a food manufacturer asked her to supervise a menu, the work was well received, and she now gets regular commissions. What made it work was publishing to a narrow audience, and keeping at it. Proposing easy yakuzen recipes anyone could follow, again and again, gradually built her following.

Finding an angle of your own that draws on your strengths, and going on providing value to an audience that needs it, is what leads to steady income.

Health and income together, through a yakuzen side business

A yakuzen side business deepens your own health knowledge, supports other people's health and earns income: three birds with one stone. Even with no experience, a clear step such as a qualification builds real knowledge and credibility. From there, online courses, cookery classes, counselling and recipe development all offer ways to earn.

The key is finding the expertise and the angle that are yours, and going on providing value. And keeping the legal points firmly in mind while moving at a pace you can sustain.
