JIMTOF 2026 — the 33rd Japan International Machine Tool Fair — runs October 26–31, 2026 at Tokyo Big Sight, organised by the Japan Machine Tool Builders' Association (JMTBA) under the theme "When technology takes off, the possibilities are limitless." As one of the world's four anchor machine tool shows alongside EMO Hannover, IMTS Chicago, and CIMT Beijing, JIMTOF concentrates Asian-Pacific machine tool, cutting tool, and metrology procurement decisions into a single six-day window.
Event Overview and Schedule Change
The Japan Machine Tool Builders' Association (JMTBA) and Tokyo Big Sight Inc. co-organise JIMTOF on a biennial cycle as the central platform for machine tool procurement decisions in the Asia-Pacific region. The 33rd edition follows JIMTOF 2024, which drew 129,018 visitors and over 300 overseas exhibitors from 18 countries.
JIMTOF 2026 marks the first time the show begins on a Monday and runs Monday through Saturday, replacing the traditional Tuesday-to-Sunday cadence to better align with B2B buyer schedules. The schedule shift, announced in JMTBA's July 2025 press release, gives factory engineers and procurement teams a full work week of weekday access without sacrificing the Saturday window for technical-school and university visitor groups.
Confirmed Japanese Machine Tool Builders
Major Japanese machine tool builders publicly listed in JIMTOF 2026 pre-show coverage include Yamazaki Mazak, DMG MORI, Okuma, Amada, Makino, Brother, Citizen, JTEKT, Matsuura, Mitsui Seiki, Nakamura-Tome, Sodick, Tsugami, and Yasda. This concentration of domestic builders — most with R&D and final assembly within Japan — is unique to JIMTOF among the four anchor shows.
FANUC anchors the controls and automation side, with its CNC and robot product lines historically occupying one of the largest single-vendor footprints at JIMTOF. Visitors can typically see live integration between FANUC controls and partner machine tools across multiple stands rather than only at the FANUC stand itself.
Yamazaki Mazak, DMG MORI, and Okuma anchor the 5-axis machining centre category, where the show traditionally reveals new spindle, ATC, and pallet-automation configurations roughly 6–12 months ahead of equivalent Western product launches at IMTS or EMO. For shops weighing whether 5-axis adoption fits their part mix and capital plan, see the 5-axis machining adoption analysis.
Cutting Tool and Metrology Vendors
The cutting tool exhibitor list publicly referenced in pre-show trade coverage includes Sandvik Coromant, Iscar, TaeguTec, Mitsubishi Materials, OSG, Tungaloy, Kennametal, and Kyocera — a comparable concentration to MACH 2026's Machining & Tooling Knowledge Hub but with stronger Japanese-vendor representation. Sumitomo Electric Hardmetal, Nikken Kosakusho, and BIG DAISHOWA typically use JIMTOF as their primary domestic launch venue.
Mitutoyo, Hexagon, Zeiss, and Renishaw cover the metrology side, with Mitutoyo's home-market presence at JIMTOF historically larger than at IMTS or EMO. For shop-floor measurement buyers, JIMTOF is the venue where Japanese-domestic instrument lines (digital calipers, micrometers, indicators, surface roughness testers) are typically demonstrated alongside their CMM and optical measuring counterparts under one roof.
The HSK taper system standardised under DIN 69893 / ISO 12164 is the dominant high-speed interface across Japanese-built 5-axis spindles shown at JIMTOF, with HSK-A63 and HSK-A100 covering the bulk of aerospace and die/mould configurations on display. For the side-by-side specs against BT and CAT, see the BT vs CAT vs HSK comparison.
Key Technology Themes
Pre-show trade coverage from SEISANZAI Japan, Modern Machine Shop, and JMTBA's own briefings point to several themes likely to dominate JIMTOF 2026:
5-axis machining and Done-in-One workflows — Japanese builders are expected to push 5-axis machining centres with integrated probing, in-process inspection, and unmanned overnight operation as a single packaged offering rather than as separate options, reflecting the Japanese domestic shift toward labour-replacement automation in mid-size job shops.
Automation, cobots, and pallet systems — Robot loading, automated pallet pools, and cobot-tended cells are expected to dominate the floor at JIMTOF 2026, building on the "automation proposals reach maturity" theme that SEISANZAI Japan identified as the defining storyline of JIMTOF 2024. For the practical ROI picture behind cobot deployment in mid-size shops, see the cobot machine tending ROI reality analysis.
AI and digital-twin integration — Tool condition monitoring, AI-assisted toolpath generation, and digital-twin simulation tied to live machine data are expected to move from R&D demonstrators toward commercially-priced add-ons at JIMTOF 2026, particularly within the FANUC, Mazak (MAZATROL), and DMG MORI (CELOS) ecosystems.
EV motor and lamination machining — Stator-and-rotor lamination stamping and motor-shaft turning cells are expected to receive larger floor space at JIMTOF 2026 than at any prior edition, reflecting Japan's continued role as a primary supplier of EV motor production equipment to Asian, European, and North American carmakers.
Sustainability and energy-efficient machining — Reduced spindle power consumption, MQL (minimum quantity lubrication), and heat-recovery systems on machine envelopes are expected on multiple stands. For the broader factory-level efficiency picture, see the CNC machining optimization guide.
Visitor Planning
Tokyo Big Sight is split between East and West Halls connected by an enclosed bridge. Plan a half-day per hall — machine tools and large automation cells typically occupy the East Halls, with cutting tools, metrology, and component vendors in the West Halls. The Yurikamome and Rinkai lines both serve the venue; the Yurikamome stops at "Tokyo Big Sight" station within walking distance of the main entrance.
UK and US Shops: Attend or Follow Recap?
For shops based in the UK or US, JIMTOF sits in the same calendar year as MACH 2026 (April, Birmingham) and IMTS 2026 (September, Chicago) — a rare three-anchor-show year that compresses major procurement decisions into a six-month window. MACH 2026 in Birmingham and IMTS 2026 in Chicago cover most of the same vendor categories, which makes the JIMTOF travel question turn on which technologies a shop most needs to evaluate hands-on.
Western shops with significant exposure to Japanese-built machine tools, FANUC controls, or Japanese cutting-tool vendors typically gain more from attending JIMTOF in person than from MACH or IMTS, because the Japanese-domestic product roadmap surfaces here first. Shops without that exposure are usually well-served by following post-show recaps in Modern Machine Shop, SEISANZAI Japan, and Manufacturing Technology Insights, then routing follow-up questions to local distributors.
Asia-Pacific Shops: Depth Advantage
For shops in Japan, Korea, Taiwan, China, and Southeast Asia, JIMTOF offers deeper coverage of EV-motor, semiconductor-equipment, and precision-die machining than any Western show, reflecting the regional industrial base. The Additive Manufacturing Area, an officially-featured pavilion, draws Asia-Pacific metal-AM equipment vendors that rarely show with the same density at IMTS or EMO.
Asia-Pacific shops are also the primary audience for the Japanese-domestic cutting tool launches at JIMTOF, since OSG, Tungaloy, Sumitomo Electric, and Mitsubishi Materials use the show as their main pre-distributor briefing venue for new grades and geometries before regional rollout.
JIMTOF 2026: Asia-Pacific Anchor Show
JIMTOF 2026 runs October 26–31 at Tokyo Big Sight under JMTBA's organisation, concentrating Japanese machine tool builders, controls, cutting tools, and metrology in a single venue. The schedule shift to Monday–Saturday targets B2B buyers, while the technology mix — 5-axis Done-in-One, automation, AI, EV motor machining, and sustainability — reflects the dominant procurement themes across Asia-Pacific manufacturing.
