暑中お見舞い申し上げます
(shochuu omimai moushi agemasu)
In Japan, it is customary to send season's greetings to family and friends during the summer. They are meant to wish loved ones safety and good health during the hottest time of the year. We hope that you stay healthy and find relaxation this summer and that you take the time to rejoice in all of the beauty and warmth that this season bestows on us.
