- Housing is not covered which is worrying us. We donft know how much or what is good normal for afanily of four? Currently we live in a small town house. and ready to downsize. We are ok with that. We are not sure about the cost (rent, electricity, water, heat, gas, .... or other fees). Have a look for houses here so you can get an idea.
https://www.homes.co.jp/ Note that renting initially is very expensive as you often need to pay nearly 6 months upfront: 2 months rent, thank you money, agency, deposit...
Utilities etc I donft remember as specially expensive. At least not compared to EU.
- Do we need a car to move aroundvisit places or people/friends? Or public transportation is good and reliable enough? Japanese public transport is the definition of reliability. Sometimes when the train by error leaves 20 seconds too early the rail company deeply apologizes.
https://www.google.co.uk/amp/s/www.bbc.com/news/amp/world-asia-4200983...Most Japanese in big cities donft have cars. You mentioned Osaka, public transport plus a bicycle to get around in your neighborhood will be all you need. For trips you can rent a car easily.
- Safty. How safe itfs for non Japanese to life there? How local interact with foreigners? very safe. Apparently safer than Canada:
https://www.numbeo.com/crime/compare_countries_result.jsp?country1=Jap.... But yes, you can get unlucky and become a crime victim in Japan.
The locals are nice but reserved towards foreigners. Very generally speaking.
- Kids are in grades 5 and 10. How to make an easy transition for them? As you might know teenagers are not easy. they will go to international school right??? Tuition paid by your husbands company, right? As others mentioned above this is the breaking point. It would not sound feasible to put them into a Japanese school at this age with no Japanese knowledge.
- Grocery cost to cook at home. Any cheap markets/farmers market/small chains which are cheaper than big names?fruits are quite expensive but generally Japan is not more expensive than EU for food (sorry canft compare with Canada). Going out for lunch can be very cheap (under 1000 yen) and for dinner you can also find cheap places.
- Learning Japanese, is it easy? Costlyjapanese for an English native speaker is among the hardest languages to learn:
https://www.effectivelanguagelearning.com/wp-content/w3tc/pgcache//lan...Now that said, Japanese grammar initially is really easy. You can start speaking simple Japanese really quickly. Not as with German or Russian if you donft have enough grammar you canft really speak properly. But learning Japanese fluently probably needs at least 2 years of full dedication. Plus/minus depending on your capabilities and dedication.
Costly, well there are free courses offered at some municipal institutions but the quality is so-so. Or you can enroll full time into a school. Really depends on how much and how well you want to learn it.
It seems that you donft know a lot about Japan. Maybe before relocating the entire family you should come over for a vacation/ reconnessaince?
