You are right, I didn't really realize that it's a few bucks extra if bought from Klook.
Looks like I will be grabbing my ICOCA/HARUKA from the airport using cash then 

Yes! You can get both as a new package - https://www.westjr.co.jp/global/en/ticket/icoca-haruka/
I don't think you can get it from the machine because they need to check your passport and make sure you're a foreigner.

First page bottom right corner. If you stay at an established hotel, try ask them.

With your super pack schedule, no way you can visit fruit bus stop.
It was inside Konagai Town which is 1 hour away from Nagasaki City.

Nagasaki only 3 places to visit....oh man....your homework are not done well.

I didn't visit Konagai before. So I ask my travel kaki from Japan and he did go.
He conclusion was:
If you go by public transport are waste of time.
You had to take normal train to Konagai Station and walk 15 minute to reach 1st strawberry bus stop Location https://goo.gl/maps/aFa3z6Q5LFZBkNby9
Next bus stop are far away, beyond reach by walking. Due to small town, bus are not frequent. Waiting at Strawberry bus stop taking bus to next fruit bus stop might take 30 - 60 minute of waiting time.

He suggestion was, If you got 3 -4 hrs to waste for this nonsense, you are good to go   

I didn't know there was such an attraction!    But yeah after googling there's about 14 types of fruit stops, so if you want to maximise ur fruity coverage don't use the buses. Better to rent car and hop from stop to stop otherwise ur waiting time will probably be longer than ur excitement.

Also Nagasaki has much more than just the A Bomb stuff but I guess not everything suits everyone's cup of matcha tea.

TBH honest i a bit regret visiting the atomic bomb museum. i got mixed feeling inside. not sure want to pity them or what. it was due to my late grandma who survived the WW2 japan invasion period in malaysia and keep telling me how suffering the family during that time.

The million dollar view is Mount Inasa ah?

Don't you get rebate on purchases if you are a visitor to Japan?

Reach at late evening can enjoy both sunset & the city night view. The sunset by the sea also quite nice d. I see a lot ppl do timelapse sun went down there.

Why don't you take the cable car and go up the mountain instead? 

Anyone here used Wiyo pocket wifi at Hiroshima and Tochigi area before? Or maybe anyone have any other recommendation? So far this is the cheapest I can find, which is RM11/day. I used it last year for Osaka, Kyoto, Kobe, Tokyo, seems okay.

There is klook event on 28th and 29th Sept, need to rsvp (free) via klook

u need to attend the event to get it
same like the previous B1F1 voucher
need to get it from the event and redeem it online

lucky u got guaranteed ticket for sagano rail train

Because Malaysia custom are not doing thier job.
Law is there but no one really do it strictly.
Still remember few year ago, When GST starting?....It got a law stated everything u brought more than RM500 above will be tax 6%, but anyone kena before?

If you're not in a rush, you can just go to the JR counter at Kansai airport and buy the ICOCA card and Haruka ticket when you arrive. You can also opt to buy the Kansai One Pass instead of the ICOCA card (works the same but comes with some added discount benefits). You can get specially designed cards only from the counter which you can keep as a souvenir.

KOP are Fancy ICOCA...just like limited edition thing for foreigners....which Japanese always good at.
Boring card make it become fancy and selling you at higher price.
