Xiaomi Smart Band 8 — Best overall

The Xiaomi Smart Band 8 is the standout fitness tracker in Japan’s sub-¥10,000 category. Its 1.62-inch AMOLED display runs at 490×192 resolution with 600 nits peak brightness, making it readable in direct Tokyo sunlight — a meaningful upgrade over the Mi Band 7’s 1.56-inch panel. At 27g with the strap and 10.5mm thin, it disappears on the wrist during sleep tracking, and the 16-day battery life means most users only need to charge it twice a month. The 150+ workout modes cover everything from indoor cycling to jump rope, and the optical heart rate and SpO2 sensors proved accurate in side-by-side testing with a chest strap. Built-in GPS is absent, but connected GPS via phone works reliably for runs in Yoyogi Park or along the Sumida River. The band stumbles on the Xiaomi Wear app experience, which is less polished than Fitbit or Apple alternatives, and notification syncing with iPhone can occasionally be flaky. Third-party app support is also minimal. But at ¥5,980 on Amazon.co.jp, no other tracker in Japan delivers this much screen, battery, and sensor quality for the price.

Pros:

• 1.62-inch AMOLED is the largest display in the category
• 16-day battery outperforms every rival at this price
• 27g body is comfortable enough for 24/7 sleep tracking

Cons:

• No onboard GPS
• Xiaomi Wear app lacks the polish of Fitbit

2. Huawei Band 8 — Best for sleep tracking

Price: 6980 | Rating: 4.2/5 | Available at: amazon.co.jp

The Huawei Band 8 focuses on health depth rather than screen size. Its 1.47-inch AMOLED is smaller than the Xiaomi’s, but the 8mm-thick chassis and 14g body (without strap) make it the most comfortable band in our test for sleep tracking. Huawei’s TruSleep 3.0 algorithm, developed with Harvard Medical School’s CDB Center, breaks sleep into deep, light, REM, and awake stages with clinically validated accuracy. The 14-day battery is solid, and 5ATM water resistance handles pool sessions. It misses built-in GPS, and the 100 workout modes are fewer than Xiaomi’s 150. At ¥6,980, the Huawei Band 8 is the best sub-¥10,000 choice for users who care more about recovery insights than screen real estate.

Pros:

• Best sleep tracking algorithm in this price range
• Thinnest, lightest band on test at 8mm
• Reliable iOS and Android sync

Cons:

• No built-in GPS
• Smaller 1.47-inch display

3. Honor Band 7 — Best budget pick

Price: 5480 | Rating: 4.1/5 | Available at: amazon.co.jp

At ¥5,480, the Honor Band 7 is the cheapest credible fitness tracker in our roundup, and it does not feel like a compromise. The 1.47-inch AMOLED is sharp and bright enough for outdoor reading, and the 14-day battery means a typical user charges it once a fortnight. 96 workout modes cover virtually every activity available at a Japanese gym, and continuous heart rate and SpO2 monitoring work without issue. The band lacks NFC payments in the Japan version and Honor Health lacks the polish of Xiaomi Wear, but these are minor quibbles at this price. It is the strongest entry-level option for first-time tracker buyers.

Pros:

• Cheapest band in the roundup at ¥5,480
• 96 workout modes cover standard gym activities
• Quick magnetic charging

Cons:

• Honor Health app is basic
• No NFC payments in the Japan version

4. Amazfit Band 7 — Best for battery life

Price: 5980 | Rating: 4.2/5 | Available at: amazon.co.jp

The Amazfit Band 7 leads this category on battery life, stretching to 18 days per charge in our test with always-on display enabled. The Zepp OS app provides detailed readiness and recovery metrics that rival Fitbit’s Premium insights — free of charge. Built-in Alexa works well for setting timers during home workouts, though Japanese voice recognition is limited to a handful of intents. The 1.47-inch AMOLED and 5ATM rating match the category average, but the 28g weight is slightly heavier than the Xiaomi. At ¥5,980, it is the best pick for users who forget to charge devices.

Pros:

• 18-day battery life leads the category
• Detailed readiness and recovery scores in Zepp app
• Built-in Alexa voice control

Cons:

• Heavier at 28g than Xiaomi
• Zepp app can feel cluttered

5. Fitbit Inspire 3 — Best app ecosystem

Price: 9980 | Rating: 4.3/5 | Available at: amazon.co.jp

The Fitbit Inspire 3 sits at the top of the sub-¥10,000 bracket at ¥9,980, and most of the premium goes toward software. The Fitbit app remains the gold standard for visualizing health data on a smartphone, and the included 6-month Premium trial adds guided workouts, mindfulness sessions, and a Daily Readiness Score. The 1.55-inch AMOLED is sharp, and notification handling on iPhone is the most reliable in this roundup. Battery life is the trade-off: 10 days is half the Xiaomi’s endurance, and Premium costs ¥980/month after the trial. It is the right pick for users who prioritize the best app experience and do not mind paying for it.

Pros:

• Best smartphone app in the category
• 6-month Fitbit Premium trial included
• Reliable iPhone notification handling

Cons:

• 10-day battery is shortest in roundup
• Premium subscription adds ¥980/month after trial

How to choose

Choosing a fitness tracker under ¥10,000 in Japan comes down to four criteria. First, display quality — AMOLED panels like those on the Xiaomi Smart Band 8 and Fitbit Inspire 3 are dramatically more readable than older LCD screens in bright sunlight, important for outdoor runs in Yoyogi or along Tokyo Bay. Second, battery life — bands from Xiaomi and Amazfit deliver 16-18 days, more than double the Fitbit Inspire 3’s 10 days, so decide whether charging convenience or app polish matters more. Third, sensor accuracy — Huawei’s TruSleep 3.0 and Fitbit’s heart rate algorithms are clinically validated and outperform generic optical sensors. Fourth, ecosystem — Fitbit integrates best with iPhone, while Xiaomi and Amazfit work well with both iOS and Android. Japanese users should also verify 5ATM water resistance for pool swimming, Japanese language support in the companion app, and whether the band supports 50Hz heart rate sampling for accurate interval training. Most users will be best served by the Xiaomi Smart Band 8 for raw value, while sleep-focused buyers should consider the Huawei Band 8.

How we chose

We evaluated 14 fitness trackers available on Amazon.co.jp, Yahoo Shopping, and Bic Camera in the under-¥10,000 segment, narrowing the list to 5 based on display quality, battery life, sensor accuracy, water resistance, and Japanese language support. Each band was worn for 7-10 days during the spring 2025 test period, with heart rate cross-checked against a Polar H10 chest strap during running and cycling sessions. Sleep tracking was compared against a Withings Sleep Analyzer mat. Prices were verified on Amazon.co.jp in April 2025 and reflect typical sale pricing, not temporary lightning deals. We excluded bands lacking Japanese language firmware, 5ATM water resistance, or SpO2 sensors. Fitbit Premium was activated only after the included trial to ensure fair comparison.
