Japanese Walking Method: Benefits, How to Start, and Walking Pace

What if a better workout didn’t mean walking farther, running faster, or spending more time at the gym?

Japan’s Interval Walking Training offers a surprisingly simple alternative: walk briskly for three minutes, slow down for three minutes, and repeat.

Known as Nihon Aruki, or the Japanese Walking Method, this approach has gained attention on social media for its practical, scienece-backed structure.

By alternating brisk walking with recovery periods, IWT offers an accessible way to improve cardiovascular fitness and endurance, while supporting weight management. With less impact than running, it provides a practical, sustainable alternative to more intense workouts.

In this article, you’ll learn how IWT works, how to get started, and how fast to walk during each interval.

What Is Interval Walking Training 

Interval Walking Training (IWT) is a walking exercise that involves walking at approximately 70% of your maximum physical capacity (slightly faster than your usual pace with a somewhat longer stride) for 30 minutes a day, four days a week. Specifically, you alternate 3 minutes of brisk walking followed by 3 minutes of slow walking. This simple routine may provide several benefits, including improved physical fitness and increased fat burning.

IWT is rooted in decades of research led by Professor Hiroshi Nose and his team at Shinshu University, who sought to understand how carefully controlled variations in walking intensity influence long-term health. 

The science behind IWT is remarkably simple. The brisk intervals raise the heart rate enough to stimulate cardiovascular and muscular adaptation, while the recovery intervals allow partial recuperation without bringing movement to a halt.

This creates a sustainable pattern that challenges the body without placing it under excessive strain, making the method suitable for older adults, beginners, and anyone seeking an effective, low-impact form of exercise.

How to Do Interval Walking Training

Here’s an illustration of the Japanese Walking Method for your quick reference:

The method is simple; alternate three minutes of brisk walking with three minutes of slow walking.

1. Warm up by walking slowly for a few minutes.

2. Walk briskly for 3 minutes. Walk faster than your normal pace, with slightly longer strides. You should feel a little out of breath but still be able to smile and speak.

3. Walk slowly for 3 minutes to recover.

4. Repeat the brisk and slow intervals 5 times.

5. Cool down with a few minutes of relaxed walking.

The recommended routine takes 30 minutes and can be performed four days per week. 

How Fast Should You Walk 

Aim for a brisk walking pace that feels like approximately 70% of your maximum physical capacity, which means walking at a pace that feels challenging but manageable. The report explains that brisk walking should feel slightly faster than your usual pace, with a somewhat wider stride. After about 5–10 minutes, you may begin to sweat lightly.

During the brisk intervals, your breathing and heart rate should increase, and speaking should become difficult, but you should still be able to say a few words. Maintain this pace for the full three minutes without jogging. The goal is to challenge yourself while remaining in control.

During recovery intervals, slow down to a comfortable pace until your breathing settles. The key is to alternate three minutes of challenging walking with three minutes of easy walking.

Benefits of Interval Walking Training

The main effects observed after five months of Interval Walking Training have been demonstrated through the “20% Rule of Interval Walking Training”:

1. Physical fitness improves by up to approximately 20%.

2. Lifestyle-related disease indicators improve by approximately 20%.

3. Annual medical expenses can be reduced by approximately 20%.

Here are the many benefits you can get if you try this training:

• Improves cardiovascular fitness: Brisk intervals raise your heart rate and help strengthen the heart.

• Supports weight management: Alternating walking intensities can increase energy expenditure.

• May improve blood pressure: Japanese studies have reported improvements in blood pressure.

• Builds leg strength: Regular interval walking can help improve lower-body strength.

• Supports metabolic health: May help improve indicators associated with lifestyle-related diseases.

• Promotes healthy aging: Helps maintain physical fitness and everyday mobility.

• Low-impact and accessible: Suitable for beginners, older adults, and people who prefer walking over running.

• Time-efficient: A structured 30-minute routine can be easier to maintain than longer workouts.

Japanese Walking Method Tips

Although Interval Walking Training (IWT) is simple, a few practical habits can help you get the most from each session.

• Stay consistent: Aim to walk three to five times a week to build cardiovascular fitness and endurance.

• Use proper form: Keep your shoulders relaxed, your head up, and your core lightly engaged. Maintain a natural stride and swing your arms comfortably.

• Choose the right pace: Brisk intervals should feel challenging but sustainable. Avoid walking too slowly or pushing yourself so hard that you need to jog.

• Follow the full interval cycle: Complete three minutes of brisk walking followed by three minutes of slow walking. Avoid shortening or skipping recovery intervals.

• Track your intervals: Use a timer, smartwatch, or interval-training app to maintain the correct pace and timing.

• Wear supportive shoes: Comfortable footwear can help reduce fatigue and discomfort.

• Stay hydrated: Drink enough water before and after your workout.

• Warm up first: Begin each session with a brief period of easy walking.

• Listen to your body: Increase your pace, intervals, or training days gradually rather than pushing yourself too hard.

• Avoid inconsistent training: Regular sessions are more effective than occasional, high-effort workouts.

Japanese Walking Method vs. 10,000 Steps

The 10,000-step approach emphasizes daily activity, while IWT focuses on walking intensity. Although leisurely walking supports overall health, alternating three minutes of brisk walking with three minutes of slow walking may improve fitness and metabolic health in less time. 

The two methods can also work together: use IWT for structured exercise while allowing daily steps to accumulate naturally.

Japanese Walking Method vs. HIIT

Both IWT and HIIT alternate periods of effort and recovery, but they differ in intensity. HIIT involves near-maximal bursts of exercise, while IWT uses controlled, challenging walking intervals. IWT is more accessible and low-impact, making it suitable for beginners and older adults.

HIIT may be better for maximizing athletic performance, while IWT focuses on sustainable, everyday fitness.

Frequently Asked Questions (FAQ) 

How soon will I see results?

Some beginners notice better stamina and breathing within two to three weeks. Other benefits may take longer and depend on your fitness level and lifestyle.

Can I make the intervals longer than three minutes?

Yes. Start with the classic three-minute brisk and three-minute recovery format, then gradually increase the intervals as your fitness improves.

Is it safe for older adults?

Generally, yes. IWT is a low-impact exercise method originally studied in older adults. Consult a healthcare professional if you have a heart condition, balance problems, or another medical condition.

Should I do interval walking every day?

Not necessarily. Three to four sessions per week are usually sufficient. Use the days between sessions for light activity and recovery.

Can I do IWT on a treadmill?

Yes. A treadmill can help you maintain a consistent pace. Adjust the speed for each interval or use its interval program.

What if I can’t walk briskly for three minutes?

Start with one- or two-minute brisk intervals and gradually build up to three minutes. The goal is to challenge yourself without becoming exhausted.

Make Walking a Lifelong Habit

The Japanese Walking Method proves that improving your health doesn’t have to be complicated or time-consuming. With just three minutes of brisk walking followed by three minutes of easy recovery, you can build endurance, support cardiovascular health, and develop a sustainable exercise routine.

Start at your own pace, progress gradually, and focus on consistency rather than intensity. Over time, IWT can become a simple daily habit that supports your health and well-being for years to come.
