Today was spent building bikes, visiting arguably the best bike shop in Tokyo, and briefly leaving central Tokyo to track down an essential piece of equptment for our journey.
For those interested, the camp stove in question is a Soto Amicus. We could have purchased it in New Zealand but found it was about $10 cheaper in Japan. We also researched travelling with gas stoves can be risky and there is a chance they can be confiscated by security, so decided it would be better to buy once arriving. That's the reason we tried so hard to find one!
