Who writes this

An engineer and writer based in Tokyo, Japan. By day, building software (web, automation, AI tooling); on the side, running indie SaaS products and embedding generative AI into operational workflows. Always insists on hands-on testing before forming an opinion — first-hand experience over secondhand reporting.

• Gadget, wearable, AR/VR device deep-dives and long-term use
• AI tooling for developers, with a focus on Claude / Anthropic ecosystem
• EVs, autonomous driving, robotics — the future of mobility
• Indie hacking, freelancing, and the economics of small teams
• Where science and culture intersect

Verification and primary sources over headline chasing. Benchmarks, measurements and concrete numbers wherever possible — and a definite buy/skip verdict at the end. Sponsored or sample reviews are always disclosed.
