Japan Hotel Foreign Guest Passport Registration with OCR

The Requirement

Under Japan’s hotel business rules, accommodations generally record the nationality and passport number of foreign guests without a Japanese address and keep a copy of the passport. Front desks copy passport details by hand during busy check-in windows, and paper copies are hard to search when authorities ask for records.

Capture Once, Confirm, Then Report

Photograph the passport at check-in, extract nationality, passport number, and name into the guest register, and keep the image under your retention policy. The passport OCR API returns structured JSON, so the same record can feed your forms, reports, and audit trail. Confirm current obligations with your local public health center and prefecture.

Workflow Applications

Server-Side Integration

Send the passport image from your backend and keep only the fields your process needs.

import base64
import os
import requests

with open("passport.jpg", "rb") as image_file:
    image = base64.b64encode(image_file.read()).decode("ascii")

response = requests.post(
    "https://api.structocr.com/v1/passport",
    headers={"x-api-key": os.environ["STRUCTOCR_API_KEY"]},
    json={"img": image},
    timeout=30,
)

if response.ok:
    data = response.json()["data"]
    print("nationality:", data.get("nationality"))
    print("passport_number:", data.get("passport_number"))
    print("surname:", data.get("surname"))
    print("given_names:", data.get("given_names"))
else:
    print("Retake or review:", response.json().get("error"))

  "success": true,
  "data": {
    "nationality": "SAMPLE",
    "passport_number": "SAMPLE",
