Hello @qishengluo, please file a Feedback Assistance report with:

• A few example images with Japanese text that the API was struggling with.
• A sample code to feed the images to the API that recreate the failure.

func visionOCR() {
        // IMG_1885.PNG
        guard let path = Bundle.main.path(forResource: "IMG_1885", ofType: "PNG") else {
            print("Failed to find image")
            return
        }
        
        guard let image = UIImage(contentsOfFile: path)?.cgImage else {
            print("Failed to load image")
            return
        }
        
        
        let reqHandler = VNImageRequestHandler(cgImage: image)
        let textReq = VNRecognizeTextRequest { req, err in
            guard let results = req.results else { return }
            for o in results {
                let o = o as? VNRecognizedTextObservation
                print(o?.topCandidates(1).first?.string ?? "")
            }
        }

        textReq.recognitionLanguages = ["ja-JP"]
        textReq.automaticallyDetectsLanguage = true
        textReq.usesLanguageCorrection = true
        try? reqHandler.perform([textReq])
    }

The above code and images work fine on iOS 17, but do not work on iOS 18 beta
