Have to leave for family emergency

Am flying out tomorrow. Any tips on what I need to do?

Am self employed and own my house so thankfully no employer or landlord, but on the other hand – have to do everything myself.

Pack

– Passport

– Residency card

– stuff for taxes? Other paperwork?

– should I bring my hanko or ship it to my lawyer?

1. Cancel the milk delivery
2. Put some money in local bank to handle automatic debits
3. turn off the main water supply at meter
4. Turn off gas at cooker
5. Rubbish?

Anything else I’m forgetting?

Edit: not sure how long. It’s a serious unexpected medical emergency.

Edit 2. Thank you so much for this advice. I’ll reply later but I am reading everything and running around frantically implementing!
