Japanese Walking: The 3-Minute Interval Walking Method Explained

Quick answer: Japanese walking (interval walking training, or IWT) means alternating 3 minutes of fast walking with 3 minutes of slow walking, for 5 rounds (30 minutes), at least 4 days a week. Researchers at Shinshu University in Japan developed it. In their studies, middle-aged and older adults who did interval walking improved aerobic fitness, thigh strength and blood pressure more than people who walked at a steady, moderate pace.

Key takeaways

• The protocol: 3 min fast + 3 min slow × 5 rounds = 30 minutes, 4+ days a week.
• Fast means "somewhat hard": about 6–7 out of 10 effort, where you can only speak in short phrases.
• Slow means easy recovery: about 3–4 out of 10.
• It's trending: one analysis of Google search data found interest in Japanese walking up nearly 3,000% year over year.
• Pair it with strength training twice a week for a complete routine.

What is Japanese walking?

Japanese walking is the popular name for interval walking training (IWT), developed by Professor Hiroshi Nose, Dr. Shizue Masuki and colleagues at Shinshu University in Matsumoto, Japan. Instead of walking at one steady pace, you alternate between brisk and easy walking. The fast intervals push your heart and leg muscles harder than normal walking, and the slow intervals let you recover so you can keep going for the full 30 minutes.

It went viral in 2025–2026. PureGym's analysis of Google search trends ranked it the fastest-rising fitness trend, with interest up nearly 3,000% year over year.

How to do Japanese walking: step by step

1. Warm up with 3–5 minutes of easy walking.
2. Walk fast for 3 minutes. Aim for about 70% of your maximum effort: breathing hard, able to say a few words but not hold a conversation.
3. Walk slowly for 3 minutes. About 40% effort: relaxed, conversational pace.
4. Repeat 5 times, for 30 minutes total.
5. Cool down and stretch your calves, hamstrings and hip flexors.
6. Do it at least 4 days a week.

How fast is "fast"? Use the talk test

Interval	Effort (0–10)	Talk test	Feels like
Fast (3 min)	6–7	Short phrases only	Late for a train
Slow (3 min)	3–4	Full conversation	Strolling with a friend

Speed is personal. A brisk pace for one person may be a jog for another. Go by effort, not by a number on a watch.

What does the research say?

In the original Shinshu University studies, middle-aged and older adults who did interval walking for about five months improved their peak aerobic capacity and thigh muscle strength and lowered their blood pressure more than a group that walked continuously at moderate intensity. Thousands of people in Matsumoto have since taken part in community interval walking programs.

The idea matches broader exercise science: intensity matters. Short bouts of harder effort challenge your cardiovascular system and leg muscles more than the same time at an easy pace.

Japanese walking vs 10,000 steps vs regular walking

	Japanese walking (IWT)	10,000 steps	Steady walking
Time	30 min, 4+ days/week	Spread through the day	Usually 30–60 min
Intensity	Alternates hard and easy	Mostly easy	Moderate
Main benefit	Fitness, leg strength, blood pressure	Daily movement, less sitting	General health
Best for	Time-efficient fitness gains	Desk workers	Beginners, recovery

They aren't mutually exclusive. You can do Japanese walking 4 days a week and still aim for more steps on the other days.

Can you do Japanese walking indoors?

Yes, especially in winter. Use a treadmill or walking pad and change speed (or incline) every 3 minutes. Put your treadmill on a large exercise mat to protect the floor and reduce vibration and noise. If you don't have a treadmill, walking briskly around a large space works, though it's harder to keep a fast pace.

Make it a complete routine: add strength twice a week

US Physical Activity Guidelines recommend at least 150 minutes of moderate aerobic activity and muscle-strengthening activity on 2 or more days a week. Japanese walking covers much of the cardio. Add two short strength sessions for the rest:

Day	Plan
Mon	Japanese walking (30 min)
Tue	Strength: squats, push-ups, rows, glute bridges (25 min)
Wed	Japanese walking
Thu	Rest or stretching
Fri	Japanese walking
Sat	Strength + Japanese walking
Sun	Rest or an easy walk

Safety tips

• Start with 3 rounds (18 minutes) if 5 feels like too much, then build up.
• Wear supportive walking shoes.
• If you have a heart condition, high blood pressure or joint problems, check with your doctor before starting a new exercise program.

FAQ

What is Japanese walking?

Japanese walking is interval walking training: 3 minutes of fast walking followed by 3 minutes of slow walking, repeated 5 times (30 minutes), at least 4 days a week. It was developed by researchers at Shinshu University in Japan.

Is Japanese walking better than 10,000 steps?

For fitness gains, interval walking is more time-efficient because the fast intervals raise intensity. Studies found it improved aerobic capacity, leg strength and blood pressure more than steady walking. Daily step counts are still valuable for reducing sitting time.

How fast should you walk in Japanese walking?

During the fast intervals, aim for about 70% of maximum effort, around 6–7 out of 10, where you can only speak in short phrases. Slow intervals should feel easy and conversational.

Can you lose weight with Japanese walking?

It burns more energy than a slow stroll and helps build fitness. Combined with strength training and a balanced diet, it can support weight management.

Can you do Japanese walking on a treadmill?

Yes. Alternate between a fast and an easy speed (or incline) every 3 minutes for 5 rounds.
