Claude Sonnet 5 ships the 16th Japanese-language page of Wellbeing Compass: a secular mindfulness introduction covering MBSR (Kabat-Zinn), Vipassana, body scan, and movement-based relaxation practices (yoga, qi gong, tai chi), with links to guided tools and evidence-based resources. The page is localized across all 11 WC languages with hreflang alternates and rich structured data. This follows rapid-fire Japanese expansion today — 15 pages in a single day, from thought-records and CBT-I sleep diaries to ACT values-clarification and now mindfulness. All pages carry the Japan crisis banner with TELL, いのちの電話, and よりそいホットライン lifelines.
