Restored WWII Japanese plane (Mitsubishi A6M Zero), Yuskukan, Tokyo
This particular type of plane was used by Kamikaze pilots in the latter stages of WWII.
This museum was next to the Yasukuni-jinja shrine which commemorates those who have died in battle Japan's history. The shrine is controversial as some of those commemorated there were classed as war criminals by the Allies.
In the past a number of Japanese Prime Ministers have made visits to the shrine causing diplomatic rows with China.
The museum gave an alternative history of WWII which I thought was pretty bad and was surprised to see given the atrocities carried out by in China and the Far East by the Japanese. The nearby Showa-kan Museum (about life during WWII and its aftermath) and the museum in Hiroshima gave much more balanced accounts of WWII.
