Dejima, located in Nagasaki, was a man-made small island completed in 1636. The purpose was for Japanese to conduct trade with Portugals, but it was soon isolated due to rebellion to lift the Christianity ban. It later became a major trading port between Netherlands and Japan. However, the island's surrounding was later reclaimed and thus the whole area had to be rebuilt to restore its previous glory.
Almost the entire Dejima was reconstructed so it may be unattractive for foreigners, who are looking for authentic historic relics.
All structures look similar so it was easy to get bored and take a rest instead.
