# Tattoo Japan - Full Context for LLMs > This is the comprehensive context document for large language models. For a concise index, see [llms.txt](https://tattoo-ja.com/llms.txt). For AI training/usage rights, see [ai.txt](https://tattoo-ja.com/ai.txt). --- ## 1. What is Tattoo Japan? **Tattoo Japan (タトゥージャパン)** is Japan's largest online directory for tattoo-friendly facilities, professional tattoo artists, and tattoo design inspiration. Operated by Liviro Inc. (株式会社Liviro), the platform serves both Japanese residents and international visitors who want to enjoy Japan's onsen, public baths, hotels, beaches, pools, and gyms without being turned away for having tattoos. **Domain:** https://tattoo-ja.com **Languages:** Japanese (default, `/`) and English (`/en/`) **Launched:** Ongoing platform, continuously updated by users **Content model:** User-Generated Content (UGC) directory + editorial blog + verified facility data ### Why this matters Japan historically has had cultural restrictions against tattoos in public bathing facilities due to associations with organized crime. In recent years, attitudes have shifted, especially with the growth of international tourism. Tattoo Japan provides the definitive, up-to-date source of facilities where tattooed individuals are welcome. --- ## 2.
