I'll soon receive a substantial amount of cash from a share sale, and I'll need to pay taxes after submitting my kakutei shinkoku in March next year. Since I will need this cash in a few months, I cannot invest the entire amount in stock ETFs like I normally would with my savings.
However, I also don't want to leave such a large sum in a current account, as it feels like a missed opportunity. Could someone advise me on safe short-term financial instruments in Japan, such as government bonds with a 6-month maturity, where I can place the funds? If the rates of those instruments are too low, is it possible to buy foreign bonds from Japan easily?
Thank you very much for your help.
