Direct answer: GetCodingTools now shows Japanese tool titles and subgroup labels when the UI locale is Japanese, and blog/news articles can publish English, Chinese, and Japanese blocks in the same markdown file.
Developer tools are often used under time pressure. Falling back to English for tool names while the rest of the chrome is Japanese creates avoidable friction—especially for JSON, webhook, and SQL utilities where the label itself is part of the mental model. The tool-copy layer now includes jaToolCopy and subgroupLabelsJa, and helpers resolve Japanese when locale === "ja".
On the content side, blog and news loaders accept locale: ja markers alongside English and Chinese. Existing guides are being backfilled so Japanese readers get the same operational detail, not a stub. Dates stay as YYYY-MM-DD for stable sorting.
Switch the language control to 日本語 to see localized tool names on the catalog and matching article bodies on Blog and News. Questions or wording fixes: sapsap@qq.com.
