Shochuu omimai are summer greetings, and is a culture in Japan where postcards asking about summer and health are usually sent to family/friends.
Summer greetings! How is everyone? I’m spending a hot, but fun summer. Please make wonderful summer memories with your family and friends! See you!
Summer greetings! Is everyone healthy? Everyone OK? I will try not to let the summer wear me down~ Recently, I’ve purposely let myself get exhausted by the summer~ ^^ Right now, I’m enjoying it healthily! Everyone, please eat and laugh a lot, and enjoy the summer~
Always keep the faith!
