It was good fun, although definitely we had some challenges as the kids were so small. Planning another trip once the twins are old enough to appreciate everything Japan has to offer! 

I salute you! I imagine you and your wife pushing twin strollers and handling all the luggage and *shudder* haha

Any plans to visit Japan again soon?

Japan is so child-friendly

I travelled to Japan a few years ago with 3 year old twins. The way we were helped at the time was second to none. So helpful with young children. 
Often other parents would come and talk to us and make us feel welcome wherever we went while we travelled across Japan.
