contacted them and say will change for me. until now also havent change zzz 

I was hoping to take the chance to change my arrival flight too

Originally:

mar 12 : KUL -> NRT
mar 21 : NGY -> KUL

Would like to change to

mar 22 : KUL -> NRT
mar 31 : OSK -> KUL

Hopefully it can be changed with minimal penalty..

it's better for you to get the Yamazaki at airports since it is tax free.

Yes.
You have to make reservation first at website // Call using hotel phone.
More expensive due to tax. Better buy at Airport Tax Free Shop.

If going Japan then forget about halal. If you really follow halal rulez so much then you can't even taste any sushi also. One thing you cna do was make sure your food no this word "豚"
Great Tour.  1 Hour duration
Free 1 glass of 12 Years Yamazaki & 25 years Hakushu & one small packed of peanuts.
Before leaving can taste one more 18 Years Yamazaki
All tasting are free.  But no refill

duty free
yamazaki distiller reserve 5500 JPY
yamazaki 12 around 6000 JPY
yamazaki 18 around 15000 JPY

Cheap also cannot bring many. Alcohol are not allow hand carried anymore But to Check in luggage. Inside luggage will
Limitation also cannot more than 5 Liters. and Alcohol cannot more than 24%

For those Transit in Japan:
Japan does not use or accept the ICAO tamper-evident duty-free bag, so travelers changing planes in Japan for other international destinations should wait to purchase any liquid, aerosol or gel duty-free items in excess of 3.4 ounces (100ml) after arriving in Japan. Passengers who have liquid duty-free items in containers larger than 3.4 ounces will not be allowed to take them through the checkpoint during the security re-check process in Japan.

Summary: 
Please don't buy any duty free alcohol or Perfume from your country if you need to do transit in Japan.
 

For those have Alcohol outside from Airport Duty Free. Such as from Factory Distiller.
No liquid more than 100ml can pass Japan Custom under hand Carried luggage. You have to drink it on spot or throw it away.
Check in Luggage can up to 5 Liters alcohol.  But once u reach Malaysia. Malaysia Custom only allow 1 liters.....ur 4 Liters of Alcohol will be tax Kaw kaw kaw kaw kaw.

For those Buy at Japan Airport Duty Free after Security Check
Less than 24% - No limitation
More than 24% to 70% - Maximum 5 Liters

But Malaysia Custom only allow you 1 Liters.    Pandai pandai la...Even Yamazaki in Japan Airport Duty Free shop is cheap but also cannot buy more than 1 Bottle......

why would you wanna get the alcohol after you land in japan?
just get it when u are returning to malaysia

If you buy at Airport Duty Free shop. You allow hand carry up to  5 Liters Per head.

Do the homework find the answer.

You can enjoy those hotel luxury onsen facility without overnight. But you must know the opening Hour.  Mostly open at noon only.
Morning and night are exclusive for hotel guest only.

if you can get it cheap in Japan, it is worth it. Rrp in Malaysia is not worth it.
Also, Yamazaki shot to fame when they were awarded for being a top whiskey.

i remember drinking it last time before they won it. that time still young. Dont know how to enjoy.Recently buy to drink and try. I feel it may be good for a 12, but for that price... a bit hesitant.

Honestly, if you can get a macallan 15 for yamazaki 12 price. macallan 15 is still a better drink to enjoy.

hahaha, go to distillery and drink FOC! two shots.
