About Tokyo Gadget — Author & Editorial Policy

Who this site is for

Tokyo Gadget is a Japan-specific guide for English speakers living in Japan. The products we cover are sold on Japan’s Amazon (amazon.co.jp) and Rakuten, and our advice assumes Japanese conditions — PSE certification, Japan’s 100V mains, domestic warranty, and local shipping. If you’re outside Japan, availability, plugs, voltage, and pricing may differ.

Author

• Operator & author: Yusuke
• Background: based outside Japan (in Thailand), using chargers and power banks daily for commuting, work, and travel. With long experience living abroad, I have hands-on familiarity with international charging conditions (voltage, plugs, carry-on rules).
• Gear I actually own and use (examples): multi-port GaN chargers, a cable-integrated power bank, a durable USB-C cable, a USB-C hub, a USB power strip, and more. Products I own and use are marked “Owner uses this,” with honest impressions and weak points.

I don’t list unverifiable qualifications or credentials. Experience-based statements are my own impressions.

Editorial policy

• How we choose products: public specs, supported standards (USB PD / Qi2, etc.), safety certification (PSE, etc.), review trends, and fit for the use case. Owned items add real-use impressions.
• Spec vs measured: we clearly separate manufacturer figures from what we’ve actually verified. We never present unmeasured values as measured.
• Both pros and cons: we write the drawbacks and cautions, not just the upsides.
• Editorial independence: we work to keep affiliate revenue from influencing rankings or conclusions. Compensation doesn’t change our assessment.
• Provided products: if a maker provides a product, we state so near that item.
• Corrections & updates: we fix errors promptly and show an updated date for significant changes. Prices, stock, and review counts change—check each product page before buying.
• Verification status: hands-on articles are marked “hands-on tested,” and public-spec comparisons “spec comparison.”

We aim for accuracy but can’t guarantee it’s current or complete. Please make purchase and usage decisions at your own responsibility after checking the latest details on each product page.
