+# OpenBrush Ukiyo-e
+
+Japanese Ukiyo-e woodblock prints from OpenBrush-75K — the only non-Western style in the parent dataset, separated here for trainers who want a dedicated Japanese woodblock corpus without downloading 75K Western paintings to filter.
+
+> **Curated subset of [jaddai/openbrush-75k](https://huggingface.co/datasets/jaddai/openbrush-75k).** Same MIT license, same caption schema, same VLM (Qwen3-VL-30B-A3B). This subset exists so you don't have to download 75,313 images to get to the 1,167 you actually want.
+
+## Why this subset
+
+Edo and Meiji-era Japanese woodblock prints. Distinctive flat color, outlined forms, asymmetric composition, and traditional Japanese subject matter (landscapes, kabuki actors, beauties, scenes from daily life).
+
+**Filter equivalent on parent:** `style == "Ukiyo-e"`
+
+## Statistics
+
+- **Total images:** 1,167
+- **Source:** OpenBrush-75K v1.1 (filtered)
+- **License:** MIT
+- **Caption schema:** v2 structured (TAGS / SUBJECT / ACTION / SETTING / MOOD / STYLE / LIGHTING / COLOR / COMPOSITION)
+
+
+## Caption schema
+
+Same as the parent. Each row has `caption_full` plus 9 individual fields:
+
+```
+**TAGS:** comma-separated standardized descriptive tags
+**SUBJECT:** Description of the main subject
+**ACTION:** Movement, gesture, what is happening
+**SETTING:** Environment and context
+**MOOD:** Emotional tone and atmosphere
+**STYLE:** Artistic technique and stylistic analysis
+**LIGHTING:** Direction, quality, temperature
+**COLOR:** Palette and color relationships
+**COMPOSITION:** Framing, balance, focal points
+```
+
+## Schema
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `id` | string | Unique identifier |
+| `image` | Image | The artwork (PNG bytes) |
+| `width` | int | Image width in pixels |
+| `height` | int | Image height in pixels |
+| `artist` | string | Artist name |
+| `style` | string | Art movement/style |
+| `genre` | string | Genre |
+| `tags` | list[string] | Standardized descriptive tags |
+| `subject`, `action`, `setting`, `mood`, `style_description`, `lighting`, `color`, `composition` | string | Per-aspect caption fields |
+| `caption_full` | string | Full structured caption |
+| `source_file` | string | Original filename |
+
+## Loading
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("jaddai/openbrush-ukiyo-e")
+print(len(dataset["train"]))  # 1,167
+
+example = dataset["train"][0]
+print(example["caption_full"])
+```
+
+## Relationship to the parent dataset
+
+This is a filtered slice of [jaddai/openbrush-75k](https://huggingface.co/datasets/jaddai/openbrush-75k) v1.1. All images, captions, and metadata are identical to those in the parent — no recaptioning or modification.
+
+If you want the **complete** OpenBrush corpus (75,313 paintings), use the parent. If you want **just this slice**, use this subset to save bandwidth and disk.
