Hmm i search around for that and it says only cover until wakayama station though?    or it covers all the way down south?

I think this Japan tour will be my once and last time. Should I explore Kansai too? What is the minimum budget? I will extend my budget.

Yeah, I will plan what needs to do on that day, gotta find what is near to airport besides Rinku. I will send off my friend to KIX in the morning, so I will store my luggage in airport before heading out on my own.

cash is still king in japan
i bring mostly cash

as for the rate, if u have changed yen like 5 months ago, that rate vs BP rate is like sky and earth

For instant bento sets, you can easily get them at any Family Mart, Lawson, 7i /7Eleven convenience stores, and many shopping malls like AEON have supermarket section that sells them. Prices & choices available may vary from each of them around 400~550 yen, but AFAIK only those in supermarkets have late nite discounts and this can be a battlezone. I saw someone quickly grabbing a bento set marked down 40% before i could reach it. Haha.

As for diapers, your asking if Japan cheaper than here, I don't think so. Good thing is, you have hand carry baggage to Japan so use it to carry diaper supplies and run them down so you can return with carry on baggage of goodies.

Look like there will be new route from AA to japan d.

KUL - Taipei - Okinawa (Naha)

Funny you should be obliged to buy souvenirs even if you don't feel the need to do so. Japan isn't like those super-cheap Chinese tours whereby you are 'forced' to buy things as you travel in the tour. The only souvenir I bought back when I went to Nagasaki is tons of Japan KitKats for myself and for gifting.  Oh and a local specialty ornament for my house deco.

Health Director-General Datuk Dr Noor Hisham Abdullah said the latest positive case – the 23rd in the country – is a 53-year-old Malaysian woman, who travelled to Japan recently.

"After arriving back from Japan on Feb 23, the patient developed fever symptoms the following day, and received treatment in a hospital in Kuala Lumpur. A Covid-19 test was done, and it was found to be positive on Wednesday (Feb 27)," he said in a statement on Thursday (Feb 27).

Why you all cancelling trip?

Malaysia 1-in-164,000 infected
Japan 1-in-172,000 infected

Malaysia higher infection rate than Japan, you are literally safer over there than over here.

Japan's coronavirus figures are likely already much higher than reported, with the infection rate suspected to be just the "tip of the iceberg," according to Masahiro Kami, the executive director of Japan's Medical Governance Research Institute, a non-profit group.
