If you’re comparing Komatsu mini excavator price options in 2026, you already know these machines hold their value well, and for good reason. Komatsu builds compact excavators that consistently rank among the most reliable in the category, backed by strong dealer networks and solid resale demand worldwide.

But pricing varies significantly depending on the model, year, hours, and whether you’re buying new or used. A brand-new PC30MR-5 and a well-maintained used PC55MR-5 sit in very different price brackets, and knowing those ranges matters before you commit. At Japan Machinery Trader, we source used Komatsu mini excavators directly from Japanese rental fleets and auctions, machines that typically carry lower hours and less wear than what you’ll find in most markets.

Below, we break down current 2026 pricing for five specific Komatsu mini excavator models, covering both new and used market values so you can budget with real numbers.

1. Japan Machinery Trader

Japan Machinery Trader sources used Komatsu mini excavators directly from Japanese rental companies and auction channels, giving you access to machines with documented operating histories and lower-than-average working hours. When you request pricing, you receive a quote based on real inspection data rather than vague dealer estimates.

How Japan Machinery Trader prices Komatsu mini excavators

Pricing reflects three core factors: the model and operating hours, physical condition as verified during a professional on-site inspection, and current Japanese auction market values at the time of sourcing. Rental fleet machines carry lower hours because they run on strict maintenance schedules and rotate between jobs, which keeps wear more predictable. This sourcing approach is a key reason the komatsu mini excavator price you find through Japan Machinery Trader competes well against dealer pricing in most international markets.

Machines from Japanese rental fleets consistently show lower hours and more predictable wear patterns than equipment sourced from private sellers or general mixed auctions.

The table below shows indicative 2026 price ranges in Japanese Yen for the Komatsu mini excavator models covered in this article. These figures reflect used, export-ready machines in good working condition sourced from Japan. Operating hours, attachments, and specific configuration all affect the final number, so treat these as realistic planning benchmarks rather than fixed prices.

What an export-ready quote includes

When Japan Machinery Trader sends you a final quote, it covers more than just the machine price. Your quote includes a full inspection report, export documentation, customs paperwork, and shipping coordination to your destination port. You won’t need a separate freight forwarder or help navigating Japanese export regulations independently. That bundled structure means the figure you see is the one you plan your budget around, with no unexpected costs appearing after you commit to a purchase.

2. Komatsu PC10UU-5

The PC10UU-5 sits at the compact end of the Komatsu mini excavator price spectrum, weighing around 1,000 kg and built for work in tight, access-restricted spaces. Its small footprint makes it a practical choice when larger machines simply cannot fit on site.

Typical 2026 price range for PC10UU-5

Used PC10UU-5 units sourced from Japan in 2026 typically land between ¥500,000 and ¥900,000, depending on operating hours and overall condition. New units carry a significantly higher price, making used Japanese rental stock the preferred route for cost-focused buyers who still want a well-maintained machine.

What moves PC10UU-5 pricing most

Operating hours are the single biggest pricing driver for this model. Machines under 1,000 hours command a premium, while units approaching 2,500 hours drop toward the lower end of the range. Attachment packages such as hydraulic breakers or extra buckets can also push the final price upward.

Rental fleet PC10UU-5 units frequently come in well under 1,500 hours, placing them in a strong value tier without reaching new-machine costs.

Where PC10UU-5 fits best on the jobsite

This machine performs best in indoor demolition, urban landscaping, and narrow trench work. Its short tail swing radius keeps it productive and safe in areas where site boundaries leave little margin for error.

What to check before buying a used PC10UU-5

Inspect the boom and arm cylinders carefully for seal leaks, and check the rubber tracks and undercarriage rollers for excessive wear. Always request a full inspection report before you commit to any purchase.

3. Komatsu PC20MR-5

The PC20MR-5 steps up to around 2,000 kg operating weight, offering more digging reach and hydraulic output than a micro-class machine. Buyers choose this model when they need more capability than the PC10UU-5 delivers but still want a compact footprint for access-restricted sites.

Typical 2026 price range for PC20MR-5

Used PC20MR-5 units from Japanese rental stock in 2026 typically fall between ¥900,000 and ¥1,500,000, depending on operating hours and overall condition. Machines with lower working hours and clean service histories sit at the top of that range, while higher-hour units with worn components pull toward the lower end.

Japanese rental fleet PC20MR-5 units regularly come in under 2,000 hours, making them a strong entry point when you’re comparing komatsu mini excavator price options across markets.

What moves PC20MR-5 pricing most

Operating hours and undercarriage condition create the largest price gaps between available units. Machines that include hydraulic attachments or additional bucket sets can add ¥100,000 or more above the base figure, so factor attachment packages into your total budget from the start.

• Hours under 1,500: sits in the strongest value tier
• Hydraulic breaker included: adds a meaningful premium
• Clean track and roller condition: holds resale price well

Where PC20MR-5 fits best on the jobsite

This model handles utility trenching, light foundation excavation, and grading in tight urban environments where larger machines won’t fit. Its short tail swing radius keeps operations safe and productive when you’re working close to walls, fences, or parked vehicles.

A secondary strength is load-and-dump work on small residential projects where truck access is limited and cycle times need to stay short.

What to check before buying a used PC20MR-5

Inspect the swing bearing and slew ring carefully for any play or grinding noise during full rotation. These components are expensive to replace and often show wear before other systems do.

Also examine the boom and arm cylinder seals for leaks and check pin and bushing clearances throughout the linkage before you commit to any purchase.

4. Komatsu PC30MR-5

The PC30MR-5 weighs around 3,000 kg and delivers more digging force and reach than the PC20MR-5, making it a better choice for deeper utility work and foundation excavation. It still fits through standard site access gates, so you keep the access flexibility that compact machines are known for.

Typical 2026 price range for PC30MR-5

Used PC30MR-5 units from Japanese rental fleets in 2026 typically fall between ¥1,200,000 and ¥2,000,000 depending on hours and condition. Japanese rental stock consistently undercuts new equipment pricing when you’re comparing komatsu mini excavator price options at this weight class.

Rental fleet PC30MR-5 units commonly come in under 2,000 hours, giving you strong remaining service life at a competitive entry price.

What moves PC30MR-5 pricing most

Operating hours and undercarriage wear create the largest price gaps between available units. Machines fitted with hydraulic attachments or quick coupler systems add a notable premium above the base machine price.

• Hours under 1,500: top value tier
• Breaker or tilt bucket included: adds ¥150,000 or more
• Clean track and roller condition: supports stronger resale value

Where PC30MR-5 fits best on the jobsite

This model handles deep utility trenching, foundation excavation, and drainage grading effectively. Its zero tail swing configuration keeps productivity high in narrow corridors where full-size machines cannot safely operate.

You’ll also find it useful on mid-size residential projects where both access constraints and dig depth push lighter compact machines past their limits.

What to check before buying a used PC30MR-5

Inspect the final drives and travel motors for oil leaks before committing to a purchase. Check boom cylinder rod surfaces for scoring or pitting, as repairs carry meaningful cost at this weight class.

Also request a full inspection report covering the swing bearing and pin-and-bushing clearances throughout the boom and arm linkage.

5. Komatsu PC55MR-5

The PC55MR-5 sits at the top of the compact class, weighing around 5,500 kg and delivering digging performance that rivals many full-size machines. Buyers choose this model when they need maximum output from equipment that still fits on access-restricted urban sites.

Typical 2026 price range for PC55MR-5

Used PC55MR-5 units sourced from Japanese rental fleets in 2026 typically fall between ¥2,000,000 and ¥3,500,000, depending on operating hours and overall condition. This komatsu mini excavator price range makes it a compelling alternative to new equipment at this weight class.

Japanese rental fleet PC55MR-5 units regularly come in under 3,000 hours, giving you strong remaining service life well below new-unit cost.

What moves PC55MR-5 pricing most

Operating hours and undercarriage condition drive the largest price differences between available units at this class. Machines equipped with hydraulic attachment packages or auxiliary hydraulic lines can add ¥200,000 or more above the base machine price.

• Hours under 2,000: top value tier
• Quick coupler and breaker included: meaningful premium
• Clean track and roller condition: supports strong resale value

Where PC55MR-5 fits best on the jobsite

This model excels at deep trench work, large utility excavation, and heavy site preparation in environments where full-size machines cannot fit. Its zero tail swing configuration keeps operations safe and productive in narrow urban corridors.

A secondary strength is bulk material handling and loading on mid-size construction projects where both cycle speed and digging reach determine daily output.

What to check before buying a used PC55MR-5

Inspect the final drives and travel motors closely for oil leaks or abnormal noise during travel. Scoring or pitting on boom cylinder rod surfaces carries real repair cost at this weight class, so examine them carefully before you commit.

Always request a complete inspection report covering the swing bearing and pin-and-bushing clearances throughout the full boom and arm linkage.
