JR pass cover it. Just sit at non-reserved seat n u will be fine. I once rush toward the train entered reserved seat n sat there w/o knowing it. The conductor is nice enough to tell me to go car no. of non-reserved  car.

Edit: super express thunderbird is the one I sat

yes, you can use suica for any metro or railway in Japan

Some restaurant accept suica as well but beware that very limited vending machine accept suica in kansai are limited to pitapa card. Otherwise tokyo area is great place for suica. Certain temple accept em too.

Since two years back (or last year, cant remember), they have harmonized all the cards in Japan, and you can use your Suica in most of the railways, even in Kansai. I cannot speak for all lines in Kansai but I have been there a few time this year for business and no issue with my Suica.

It should be icoca card. Pitapa is a postpaid card which is unlikely available for foreign tourist, you will pretty much have no hassle in going through the trains and subway since most ic cards are compatible with each other. There might be some inconvenience in shopping using the cards though like it has mentioned above

Used it in my last trip. Coverage is good, except Arashiyama suffer a bit signal degradation, but considerable since its mountainous area. Other than that, unlimited full speed, which i can do anything. Done a speed test which the speed is always between 5 mbps to 30 mbps depends on the location.

You can directly return the device and claim back the deposit at the counter of KLIA2, unless you are doing flight transfering directly to Johor once you reach KLIA2.

A dilemma. I'll be in Japan for one week, and another week in HK, then only I'll head home. In HK, I can buy and use a prepaid SIM worth less than $40 for 1GB lasting for a month; definite choice. In Japan, if I'm to get the WiFi rental from Malaysia, I'll ahve to pay for the 2 weeks duration even though I'm only using it in Japan for a week because I'm only returning the device 2 weeks later. If I'm getting the WiFi rental from Japan, instead, I'll be paying twice the amount of money offered locally in KL. Any suggestions how I may turn around with this?

Buffa when are you going? I bought the yokoso sim as well. However I contacted the SG company instead since they offer the 91 day card. and shipping was 5 SGD

Sounds great.. but I'm goin on the 7th till 20th.. hopefully the weather doesn't change too much and it's not too cold.. i still wanna see the autumn leaves 😓

but my wife want to go kyoto badly  .  thinking to do 4 days tokyo and 3 days kyoto. but my concern is the travelling from tokyo to kyoto vice versa.

Did loads of research on the cheapest way to get internet in Japan. Previously I rent portable routers but then I stumbled upon this:

Will be using it with a handphone that I'll be bringing along.

Pros:
- Super cheap, RM92 only after 15% discount. That equates to RM6.13/day if you use for 15 days
- 3.5GB with max 500mb/day, sufficient if you don't plan to stream a lot of videos. Usually back in Malaysia my normal usage is 1GB/week if I stream a lot of video
- No extra surcharge for router insurance, no risk of loss/damage of router
- No need to deal with picking up and posting back the router

Cons?
- You'll need a compatible smartphone
- If you use tethering on your smartphone to be shared with your party, your phone will lose battery faster
