re: Vietnam and Japan Advice

I've never been to Vietnam, but have been to Osaka, Kyoto, and Tokyo.

Are you flying into Osaka or Tokyo? Because if you're doing Kyoto it is easier to get to from Osaka vs. Tokyo and you're not backtracking. There's a commuter rail from Osaka to Kyoto for about $15usd.

Kyoto was my favorite city in Japan. It's historic and modern at the same time. It's full of restaurants and bars and just a lot to do. Plus it's the cleanest city I've ever seen.

We took the bullet train from Kyoto to Tokyo. It took about 1.5 hours and was $150usd. If you take the train from Kyoto stop at the department store inside the station and get a Wagyu beef ekiben box (and some beers) for the ride.

Tokyo was pretty cool, it's impossible to see everything in even a week. The subway is super expansive and efficient. Getting around should be no problem.
