⚡ WHO THIS IS FOR
• Japanese expats living in Europe, the UK, the Middle East, China, or any 220-240V country who want to keep using their Japanese rice cooker, audio amp, electric kettle, or vacuum.
• Audio collectors running vintage or current Japanese-domestic amplifiers, CD players, or hi-fi components in countries with 230V wall power.
• Travelers and short-term residents bringing a Japanese hair dryer, electric razor, or kitchen appliance to a 220-240V destination.
• Anyone who wants to use a Japan-spec electronic on European/Middle Eastern/Chinese power without buying a separately-spec'd international model.

⚠ BEFORE YOU BUY — PLEASE CHECK
• Step-DOWN transformer (220-240V → 100V). This unit drops European/Middle Eastern/Chinese 220-240V down to Japanese 100V. It does NOT step UP — if you need to run a 220V appliance on Japanese 100V power, you need a different model.
• Total load must not exceed 300 W (VA). Add up the wattage of all devices plugged in at once. Common safe-zone examples: rice cooker (200-300W), audio amplifier (50-150W), table lamp (10-60W), electric razor (20W). Avoid: hair dryer (1200W+), microwave (1000W+), iron (1000W+).
• Frequency is NOT converted. The transformer passes the input frequency through unchanged (50 Hz in, 50 Hz out / 60 Hz in, 60 Hz out). Most modern Japanese electronics handle both frequencies, but motor-based appliances designed strictly for 60 Hz (some old fans, vintage clocks, certain microwave ovens) may run slightly slower on 50 Hz power.
• Type C plug — fits most of Europe and a few other regions. The attached cord ends in a Type C (Europlug) two-pin plug, fitting standard outlets in continental Europe, the Middle East, and many other 230V regions. For UK Type G (3-pin) outlets you will need a separate plug adapter. Australia / New Zealand use Type I and also need an adapter.
• Heavy and not battery-powered. 2.25 kg of copper, steel, and metal housing. This is a stationary transformer for use at a fixed location, not a travel pocket adapter. Plan to leave it at your destination address.
• Japanese-language instruction manual. Operation is plug-in and use — there is nothing complex to operate. The label printed on the unit shows specifications in English.
Why this one
🇯🇵
Made in Japan
Manufactured in Japan by TGK (Tokyo General Kogyo), a Japanese transformer specialist that has been continuously producing power transformers since 1949 — over 75 years of accumulated craft.
🛡️
Built-in thermal protector
An internal thermostat cuts power if the unit gets too hot — protecting both the transformer and your connected appliances from overload damage. A safety feature missing from many bargain travel transformers.
⚡
300 VA capacity
Enough headroom for most Japanese kitchen appliances (rice cookers, electric kettles), audio components, lighting, and small electronics. Two Japanese Type A outlets let you run two devices simultaneously.
🌍
Wide input range
Accepts 220V to 240V input — works correctly across Europe (230V), the Middle East, China (220V), and most other 230V regions. The factory tap is set to 230V for the broadest compatibility.
🔌
Plug-and-play simplicity
No switches, no settings, no display. Plug the cord into a 230V wall outlet, plug your Japanese device into the Type A socket, turn it on. Reliable, transparent, and predictable — the way good engineering should be.
🏠
A practical solution that lasts
Single-phase, single-winding construction with a metal housing. Solid copper windings on a quality core — this is the kind of transformer you set up once at a desk or kitchen counter and forget about for years.
