Sad to say I still have not find the time to buid it. Maybe lucky for me, Haha.... I admit I took a look at the instruction for a couple of time and I knew it will not be easy.
For this trip to Tokyo, I found that Kawada came out with more Nano Block product. There is another super high level 1000 plus set of a Japanses castle (Like the Yamato). And they also came out with many more easier smaller sets.
I grab the Tokyo Tower and the Hokkaido Inu.
I told myself better start with the easier one and boy was I correct.
The Hokkaido Inu set took me 1.5 hours to complete! The blocks are quite small and you spent more time looking for time.
Anyway here is the finished Hokkaido Inu.
Tokyo Tower Here I come!
Coin added for scale.
