+
+## Model description
+
+This is a Japanese RoBERTa large model pretrained on Japanese Wikipedia and the Japanese portion of CC-100 with the maximum sequence length of 512.
+
+## How to use
+
+You can use this model for masked language modeling as follows:
+```python
+from transformers import AutoTokenizer, AutoModelForMaskedLM
+tokenizer = AutoTokenizer.from_pretrained("nlp-waseda/roberta-large-japanese-seq512-with-auto-jumanpp")
+model = AutoModelForMaskedLM.from_pretrained("nlp-waseda/roberta-large-japanese-seq512-with-auto-jumanpp")
+
+sentence = '早稲田大学で自然言語処理を[MASK]する。'
+encoding = tokenizer(sentence, return_tensors='pt')
+...
+```
+
+You can fine-tune this model on downstream tasks.
+
+## Tokenization
+
+`BertJapaneseTokenizer` now supports automatic tokenization for [Juman++](https://github.com/ku-nlp/jumanpp). However, if your dataset is large, you may take a long time since `BertJapaneseTokenizer` still does not supoort fast tokenization. You can still do the Juman++ tokenization by your self and use the old model [nlp-waseda/roberta-large-japanese](https://huggingface.co/nlp-waseda/roberta-large-japanese).
+
+Juman++ 2.0.0-rc3 was used for pretraining. Each word is tokenized into tokens by [sentencepiece](https://github.com/google/sentencepiece).
+
+## Vocabulary
+
+The vocabulary consists of 32000 tokens including words ([JumanDIC](https://github.com/ku-nlp/JumanDIC)) and subwords induced by the unigram language model of [sentencepiece](https://github.com/google/sentencepiece).
+
+## Training procedure
+
+This model was trained on Japanese Wikipedia (as of 20210920) and the Japanese portion of CC-100 from the checkpoint of [nlp-waseda/roberta-large-japanese](https://huggingface.co/nlp-waseda/roberta-large-japanese). It took a week using eight NVIDIA A100 GPUs.
+
+The following hyperparameters were used during pretraining:
+- learning_rate: 6e-5
+- distributed_type: multi-GPU
+- num_devices: 8
+- total_train_batch_size: 4120 (max_seq_length=128), 4032 (max_seq_length=512)
+- max_seq_length: 512
+- optimizer: Adam with betas=(0.9,0.98) and epsilon=1e-6
+- lr_scheduler_type: linear
+- training_steps: 670000 (max_seq_length=128) + 70000 (max_seq_length=512)
+- warmup_steps: 10000
+- mixed_precision_training: Native AMP
