Brief answer: A hukou can supplement relationship proof, but a notarized kinship certificate from a notary office is usually still required to meet Japanese tax office formal requirements.
Detailed explanation
Chinese hukou records household head and relationships among applicant and parents—important supplementary material. However, Japanese tax offices typically require formal notarized proof. Apply for kinship notarization at a notary office, using the hukou as supporting basis. Submitting uncertified hukou copies alone has low approval likelihood. If birth medical certificate and hukou are consistent, notarize both together. Local tax office requirements vary slightly. Which materials are accepted is determined by the tax office.
