Looks like the "right angle" cutter is the Kaijirushi KHS Butter Knife

I like the associated butter tub (frequently bought together section), what are the imperial butter sizes for it at my local American grocery store...?

Yeah Amazon JP is great, plus it's handy to already have one if you plan to make a trip to Japan. Both times that I went, I already had an account so it was super easy to order the SIM I wanted from Amazon to my hotel a couple days before arriving.

As far as shipping to the USA, YMMV, but when you can order items with delivery here then it's super awesome and generally fairly quick (aside from during COVID times with slower logistics).

You were able to order a SIM card online? Did you have to do anything to activate it? I was under the working understanding that Japan required government ID verification for SIM cards.

SIM cards are widely sold at vending machines in airports and train stations in Japan. I believe that the ID requirement is waived if the SIM has limited validity, as these tourist-oriented SIMs do.

It was a tourist one (something like 10GB for 21 days). You just open the package and activate it with a credit card on the company's website. I think you need to provide flight info for your return trip leaving the country and that's how they verify you're a tourist.

You can do this with Amazon.co.uk too

The UK is my go-to source for black market medical products. You can get contacts shipped without a prescription because its not required in the UK. Also some OTC cosmetics and sunscreen is way better because they don't drag their feet on approving new ingredients for 20 years like the FDA.

I recently ordered a couple of Japanese books from Amazon Japan and they were delivered in under 48 hours (to the UK).

Sounds fun, I'm making an account. How do you pay? I see internet money and atm options.

I pay using my ordinary (UK) credit card.

I don't know whether to thank you or curse you.
