Inclusion Criteria:

• Patients from whom written consent to study participation has been obtained, either from the patient personally or from the patient's legal guardian

• Patients with neurological signs equivalent to between 4 and 22, inclusive, on the NIHSS

Exclusion Criteria:

• Patients with disability equivalent to an mRS score of 2 or more from before onset
• Patients being treated with antibiotics for an infection at registration
• Patients who have received or are planning to receive treatment for their primary disease with a prohibited concomitant medication (e.g., a thrombolytic drug) or with a prohibited concomitant therapy (e.g., intravascular therapy)
• Patients for whom the (sub)investigator judges the efficacy endpoints (e.g., NIHSS, mRS, BI) that have been selected for this study can not be measured appropriately, such as patients who are not expected to achieve improvement of 4 or more on the NIHSS because of nerve symptoms that have been present since before the onset of cerebral infarction, Alzheimer's dementia patients, or Parkinson's disease patients
• Patients with severe consciousness disturbances (Japan coma scale ≥ 100)
• Patients with clear concurrent peripheral vascular disease or peripheral neuropathy for whom the (sub)investigator judges the neurological tests could not be performed properly
• Patients with severe renal impairment (e.g., patients with eGFR < 30)
• Patients with severe hepatic impairment (e.g., ALT, AST, or gamma-GTP > 2.5 X ULN)
• Patients with platelet count < 100,000/mm3
• Patients diagnosed by MRI on admission with a disease other than stroke (e.g., intracranial bleeding, subarachnoid bleeding, arteriovenous malformations, Moyamoya disease, brain tumor) or with cerebral aneurysm with a maximum diameter > 7 mm
• Patients with prior or current drug abuse or alcohol dependence
• Patients with prior (or current) malignant tumor within 5 years before stroke onset
• Patients with a past history of hypersensitivity to edaravone drug products
• Patients with concurrent heart disease severe enough to warrant admission and treatment (e.g., acute myocardial infarction, cardiac failure) and with problems with their overall condition judged by the (sub)investigator to be unsuitable for study participation
• Patients for whom MRI tests cannot be performed
• Male or female patients who do not consent to practice contraception from the date of consent until the day after the administration of the last dose of study drug
