NGK Ceramic Technology and Pokémon Electricity Technology for
a Brighter World

An evening garden party. Enticed by the lights that brightly illuminate the family enjoying itself around the dinner table, the electric Pokémon Pikachu appears. It runs around excitedly beneath the brilliant light. This bright world is made possible by ceramic technology that sustains electricity.


Supporting many tons of transmission lines while weathering blizzards and other environmental factors, insulators are vital for stable power supply, and part of NGK’s roots in ceramics.

NAS Batteries

NGK achieved the world’s first practical application of megawatt-level electricity storage systems. Boasting high capacity, long duration and high energy density, NAS is effective in stabilizing renewables, among other uses. NAS and the NAS logo are trademarks of NGK INSULATORS, LTD., registered in the U.S. and other countries.

Ceramics for Purifying Automotive Exhaust

Ceramics essential for cleaning car exhaust fumes. NGK maintains the air we breathe through Gasoline and Diesel Particulate Filters that remove particulate matter, and Honeyceram, a honeycomb-structured ceramic with walls just 0.05mm thick.

NOx Sensors

The world’s first car-mounted sensor capable of precisely measuring NOx concentration in real-time.

NGK Ceramic Technology and Pokémon Technology for an Evolving
Motorized Society,
Protecting our Beautiful World

Technology for an Evolving Motorized Society, Protecting our Beautiful World The fire-flying Pokémon Charizard appears to entertain a young girl stuck in traffic on a weekend drive. It soars majestically through the air like a circus performer.This beautiful sky is made possible by ceramic technology that keeps our air clean.

NGK Ceramic Technology and Pokémon Technology for a growing
Information Society,
enabling Convenient Lifestyles

A young woman begins living alone in the big city after leaving home. In her room, the electric Pokémon Magnemite looks on as she makes a video call to her parents. Eager to join in the conversation, it leaps into the phone and teleports. This convenient lifestyle is made possible by ceramic technology that sustains our information society.

Ceramics for Semiconductor Manufacturing Equipment

Hi-performance heaters for processing silicon wafers are made possible by ceramics with superior corrosion resistance, thermal conductivity, insulation and uniform machining. These ceramics are essential for manufacturing the semiconductors used in electronic devices.

Wafers for electronic devices

NGK develops substrate materials for key components that improve the performance and functions of electronic devices, including GaN (Gallium Nitride) wafers for next-generation power semiconductors, and bonded wafers for SAW filters which raise the quality of smartphone calls.

Beryllium Copper

Utilizing the superior properties of copper, these alloys combine an outstanding spring performance and high strength rivaling special steel.

Optical Package

Ceramic electronic components instrumental in the field of optical data communication, which sustains our information society.

Subnano-ceramic Membranes

A ‘molecular sieve’ that uses tiny pores of less than a nanometer to separate only specific gases from mixtures. Contributes to protecting the Earth’s environment by cutting CO2 emissions far more than conventional methods.

Chip-type Ceramic Secondary
Batteries – EnerCera

An ultra-thin battery that can be built into ultra-compact sensors or next-generation credit cards, helping to bring greater convenience to lifestyles of the future.

NGK Ceramic Technology and Pokémon Creating and
Protecting Our Future

NGK Insulators has continued to refine ceramic technology since its founding in 1919. Even as times change, this technology has supported lifestyles while upholding the harmony between people and the natural environment. In order to build a more abundant future while ensuring we leave a worthy legacy, NGK offers the world a wide range of unrivaled and unique products embodying the potential of ceramic.


Type : Electric

Whenever Pikachu comes across something new, it blasts it with a jolt of electricity. If you come across a blackened berry, it's evidence that this Pokémon mistook the intensity of its charge.


Type : Ghost-Fairy

Its actual appearance is unknown. A scholar who saw what was under its rag was overwhelmed by terror and died from the shock.


Type : Fire-Flying

Charizard flies around the sky in search of powerful opponents. It breathes fire of such great heat that it melts anything. However, it never turns its fiery breath on any opponent weaker than itself.


Type : Normal

Snorlax's typical day consists of nothing more than eating and sleeping. It is such a docile Pokémon that there are children who use its expansive belly as a place to play.


Type : Electric-Steel

Magnemite attaches itself to power lines to feed on electricity. If your house has a power outage, check your circuit breakers. You may find a large number of this Pokémon clinging to the breaker box.


Type : Water

Squirtle's shell is not merely used for protection. The shell's rounded shape and the grooves on its surface help minimize resistance in water, enabling this Pokémon to swim at high speeds.


Type : Water-Ice

People have driven Lapras almost to the point of extinction. In the evenings, this Pokémon is said to sing plaintively as it seeks what few others of its kind still remain.
