UK MiFIR professionals/ECPs-only/No EEA or UK PRIIPs KID: Manufacturer target market (UK MiFIR product governance) is eligible counterparties and professional clients only (all distribution channels). No EEA or UK PRIIPs key information document (KID) has been prepared as the Securities are not available to retail investors in the EEA or in the United Kingdom, respectively.

Settlement Period: The closing will occur on April 20, 2023, which will be more than two Tokyo business days after the date of this pricing term sheet. Rule 15c6-1 under the Securities Exchange Act of 1934 generally requires that securities trades in the secondary market settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the second business day before the delivery of the notes will be required, by virtue of the fact that the Securities initially will settle in T+4, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes prior to the second business day before the delivery of the notes should consult their own advisors.
