things that japanese hate ppl(tourist) do

i always wanted to ask ...this applies to other country as well
regarding the immigration slip
there will be a column regarding where u will be staying
so if one booked airbnb, what would u write on that column?

If what is written in Wikipedia is correct, then you shouldn't throw it away. Instead bring it back to the shrine or temple to dispose it.

From Wikipedia (https://en.wikipedia.org/wiki/Omamori):

Old amulets are usually returned to the same shrine or temple they were purchased at so they can be disposed of properly. It is most common for amulets to be returned on or slightly after New Year’s. This way the shrine/temple visitor has a fresh start for the New Year with a new omamori.

Throwing an amulet in the trash is also highly discouraged. Old omamori should not be placed in trash with other commonly discarded rubbish, but rather treated with respect. Usually they are burned. Burning the old amulet is meant to be a sign of respect to the deity that helped out the person throughout the year.

For those interested in the IIJmio 1GB for 1 month simcard, JTB sells it at their KL and Shah Alam branches. Currently its RM122 based on current exchange rate.
The guy told me to activate it here in Malaysia with wifi connection, then can use it immediately once you touch down in Japan.
I usually fill in the address, sometimes simplified address like which area the unit will be at.
If I am staying in multiple places during my trip and there's a hotel, I'll just put the hotel name and location.

Otherwise, full addresses is fine.
I didn't even know the omamori is for a years usage.
I still have one hanging in my car.
