Looking for a gift idea

Hello! I'm looking for a gift idea for my boyfriend who's been living and working in Tokyo. It's been okay for him there but it's just a few things that make it a little rough like the daily commute to his job, especially in the summer, whew... and also those earthquakes too... I hope someone who understands what it's like can help me find something that would make his daily life a bit better.
Thank you so much for reading!!
