Sorry to hear about it all, but no one was hurt, and life goes on for everyone. Do not let it stress you to much, your boss should be working with the homeowners insurance, and money and tools should be waiting when you return hopefully. You may be empty handed on your flight to Japan, but then your hands will be full of loving family.
@bashadow thank you. Yes, the insurance will hopefully cover our tools, but I doubt they will re-imburse us for the work done. I don't know though having never been through something like this.
Yes, you are right my heart will be full upon seeing my family.
