    Market context

    Key market insights, trends, news and related events to help you understand the bigger picture.

    Tokyo, Japan — Kanto region, Asia-Pacific

    Why it matters

    Japan's GX (Green Transformation) programme targets carbon neutrality by 2050 and treats thermal power as a bridge technology that must itself decarbonise, driving demand for hydrogen and ammonia co-firing, CCUS, high-efficiency gas turbines and biomass conversion. ZERO-E THERMAL EXPO runs inside RX Japan's World Smart Energy Week at Tokyo Big Sight — one of Asia's largest energy gatherings — giving exhibitors and visitors direct access to Japanese utilities, EPCs, trading houses and government buyers in the world's fourth-largest electricity market.

    Industry trends

    Key trends shaping this market and its wider industry.

    01

    Hydrogen and ammonia co-firing in existing thermal fleets

    Japanese utilities and OEMs are piloting 20–50% ammonia co-firing and large-frame hydrogen gas turbines as near-term routes to cut emissions from existing coal and LNG plants without full replacement.

    02

    CCUS as a retrofit path for coal and gas

    Carbon capture, utilisation and storage retrofits for thermal plants are moving from demonstration to feasibility studies, supported by government-backed storage hub programmes in Asia-Pacific.

    03

    Nuclear restarts reshaping the thermal mix

    As reactors restart in Japan, thermal capacity is increasingly positioned as flexible balancing and backup generation, shifting demand toward fast-start, high-efficiency units and digital dispatch tools.

    04

    Digitalisation and AI for plant operations and maintenance

    Predictive maintenance, digital twins and remote monitoring are being deployed to extend the life and improve the flexibility of ageing thermal assets as they cycle more frequently.

    05

    Biomass and waste-to-energy co-firing

    Biomass co-firing and municipal waste-to-energy remain commercially viable low-carbon thermal options, particularly in Japan and Southeast Asia where fuel supply chains are being scaled.

    Thermal power and energy transition event circuit

    Start 6–9 months ahead for exhibiting (stand selection and freight), and 2–3 months ahead for visiting.

    ZERO-E THERMAL EXPO sits within a global circuit of power-generation and energy-transition events. Tokyo serves the Asian spring cycle, while Europe and the US host the major autumn and winter peer shows — useful for multi-region exhibiting plans and for benchmarking audience and pricing.

    Q1 (January–March)

    Asian cycle peaks with World Smart Energy Week and ZERO-E THERMAL EXPO in Tokyo; book stand space and hotels early because of cherry-blossom season demand.

    Q2–Q3 (April–September)

    Europe and technical-association cycle — Enlit Europe and CIGRE Session in Paris; abstract and stand deadlines typically fall 4–6 months before the event.

    Q4 (October–December)

    US and Asian autumn cycle — POWERGEN International and Enlit Asia; exhibitor contracts are usually issued 3–4 months out.

    Peer events identified from public industry event calendars and organiser websites; verify current dates, venues and pricing directly with each organiser before committing budget.

    Visa & entry documents

    Check the latest visa requirements and entry guidelines before travelling.

    Visa not required
    ATA Carnet: accepted

    Most European, North American and several Asia-Pacific nationalities can enter Japan visa-free for up to 90 days for business-meeting purposes. Register your arrival details on Visit Japan Web before departure to speed up immigration and customs.

    Japan admits goods temporarily under ATA Carnet (exhibition materials, professional equipment and commercial samples). Confirm the carnet is validated for Japan with your national chamber before shipping to Tokyo Big Sight.

    Weather

    March in Tokyo is early spring: daytime highs average around 13–14 °C (55–57 °F) with overnight lows near 5–6 °C (41–43 °F), and roughly 110–130 mm of rain spread over about 10–12 days. Pack layers and a compact umbrella; cherry-blossom season starts in late March, so hotel rates rise and rooms sell out early.

    Plan for the climate

    Check temperatures and pack accordingly

    Venue connectivity

    Confirm mobile roaming or local SIM options for business visitors to Japan.

    Ride-hailing

    Taxis

    Public transit

    Car rentals

    Cultural notes

    Useful information to help you have a smooth and respectful visit.

    Tipping

    Tipping is not customary and service charges are normally included. A polite thank-you is expected instead — leaving cash can cause confusion in taxis, restaurants and hotels.

    Business cards and punctuality

    Exchange meishi with both hands and a slight bow, and take a moment to read the card before putting it away. Arrive a few minutes early for booth appointments and meetings; punctuality signals respect.

    Cash, IC cards and train etiquette

    Suica/PASMO IC cards work on trains, buses and many shops, but smaller restaurants and some taxis remain cash-only — carry some yen. Keep phones on silent in trains, avoid eating while walking, and expect orderly queues at stations and venue entrances.

    Plan your trip

    Planning

    Best day to visit: Day 2 — Thursday 25 March 2027

    Opening day draws the largest crowds and the formal opening activity, while day three typically shortens as stands pack down. Day two combines a full conference programme with calmer aisles, so exhibitor teams have time for substantive technical and commercial conversations. If you are actively sourcing equipment, extend into the morning of day three to revisit shortlisted stands and close meetings.
