YomiToku is a proprietary document analysis engine specialized for Japanese. This Lite edition runs a lightweight recognition model for higher throughput and lower cost per page, with slightly lower accuracy than the standard edition. It is a good fit for high volume batch processing and cost sensitive workloads. It integrates AI OCR plus layout and table parsing models, accurately structuring vertical text, multi column documents, and complex business forms. It supports a wide range of use cases, including generating data for RAG / search, creating searchable PDFs, and extracting information from table data. We provide **yomitoku-client** as a client SDK to help you use this product more conveniently.For more details, please refer to the link below: https://github.com/MLism-Inc/yomitoku-client For long-term or large-scale use, this product is also available through private offers.Please contact our support team for pricing information.

This is the Lite edition of YomiToku. It runs a lightweight recognition model that delivers significantly higher throughput and a lower cost per page than the standard edition, with slightly lower recognition accuracy. It is designed for high volume batch processing and cost sensitive workloads, such as digitizing large document archives, building RAG / search indexes from bulk data, and continuous ingestion pipelines. Layout analysis, table structure recognition, and the response format are identical to the standard edition, so you can move between the two editions without changing your integration. If your workload prioritizes maximum recognition accuracy over throughput, we recommend the standard edition instead.

Highlights
Each model is specifically trained for Japanese document images, supporting the recognition of over 7,000 Japanese characters, including vertical text and other layout structures unique to Japanese documents. (It also supports English documents.)
Equipped with four AI models trained on Japanese datasets: text detection, text recognition, layout analysis, and table structure recognition. All models are independently trained and optimized for Japanese documents, delivering high-precision inference.
By leveraging layout analysis, table structure parsing, and reading order estimation, it extracts information while preserving the semantic structure of the document layout.
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You pay by the hour for the compute instance that runs document analysis in your own AWS account. The ten dimensions pair five instance types with two processing modes. Three instance types use GPU acceleration, and two use general-purpose CPU compute. Each instance runs in either batch mode, for processing large volumes of documents, or real-time mode, for on-demand requests. Pick the instance size that fits your workload and the mode that matches how you send documents. Charges accrue per host hour that the instance runs. This billing covers software use; the AWS instance is billed separately.
Top-of-mind questions for buyers
What does one host hour cover, and does the AWS instance cost come on top?
One host hour is one hour that a single deployed SageMaker endpoint instance runs. The listing meters this software use per running hour. The underlying AWS compute charge for that instance is billed separately by AWS. Both appear on your AWS invoice.
How does batch mode differ from real-time mode when it comes to cost?
Both modes bill per host hour on the same instance types. Real-time mode keeps an endpoint running to answer on-demand requests, so hours accrue while it stays up. Batch mode processes large document sets in scheduled runs, so hours accrue during those jobs. Choose the mode matching how you send documents.
Am I charged when the endpoint is idle or stopped?
Charges accrue per host hour that the instance runs. A real-time endpoint left running keeps accruing hours even without active requests. If you shut the endpoint down, software host-hour charges stop. Underlying AWS storage or other resources may still bill separately.

An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Deploy the model on Amazon SageMaker AI using the following options:
Real-time inference
Deploy the model as an API endpoint for your applications. When you send data to the endpoint, SageMaker processes it and returns results by API response. The endpoint runs continuously until you delete it. You're billed for software and SageMaker infrastructure costs while the endpoint runs. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Deploy models for real-time inference .
Batch transform
Deploy the model to process batches of data stored in Amazon Simple Storage Service (Amazon S3). SageMaker runs the job, processes your data, and returns results to Amazon S3. When complete, SageMaker stops the model. You're billed for software and SageMaker infrastructure costs only during the batch job. Duration depends on your model, instance type, and dataset size. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Batch transform for inference with Amazon SageMaker AI .
