+The default MeCab-based Korean tokenizer requires:
+
+- [mecab-ko](https://bitbucket.org/eunjeon/mecab-ko/src/master/README.md)
+- [mecab-ko-dic](https://bitbucket.org/eunjeon/mecab-ko-dic)
+- [natto-py](https://github.com/buruzaemon/natto-py)
+
+For some Korean datasets and tasks, the
+[rule-based tokenizer](/usage/linguistic-features#tokenization) is better-suited
+than MeCab. To configure a Korean pipeline with the rule-based tokenizer:
+
+> #### Rule-based tokenizer
+>
+> ```python
+> config = {"nlp": {"tokenizer": {"@tokenizers": "spacy.Tokenizer.v1"}}}
+> nlp = spacy.blank("ko", config=config)
+> ```
+
+```ini
+### config.cfg
+[nlp]
+lang = "ko"
+tokenizer = {"@tokenizers" = "spacy.Tokenizer.v1"}
+```
+
+<Infobox>
+
+The [Korean trained pipelines](/models/ko) use the rule-based tokenizer, so no
+additional dependencies are required.
