Point 5 doesn't necessarily help solve your issue. At this point in time it seems like your connectivity with Japanese IP addresses is flaky and the only reasonable way to go about on it is to get a network technician to diagnose your situation.

However, if you prefer to diagnose the situation yourself you'll need to work with networking tools such as tracerouting but a more specific case for this matter is requiring the use of something known as lft or layer four traceroute.

I have covered lightly in my blog about how networking sort of works in a nutshell and the link is actually in this page - towards the bottom. The rest will be up to you to decide whether or not will you want to do it yourself or you prefer to have someone whom can physically diagnose your situation for you.

In most cases however, these might be temporary but if it spans for more than a day or two then it is definitely intermittent routing issue - technically speaking.

A possible case to alleviate the issue might be to use VPN but by no means this is a guaranteed method and you may need to try at least five different VPN providers.
