Japanese scientist Akira Yoshino and his wife attended a banquet in Stockholm held to celebrate this year's Nobel laureates.
Yoshino received the Nobel Chemistry Prize on Tuesday along with his co-winners, US scientist John Goodenough and Stanley Whittingham from Britain.
About 1,300 people attended the banquet at Stockholm's City Hall. They included the Swedish royal family, government officials and members of the prize selection committees.
Yoshino escorted his wife Kumiko to the central table where they sat among the Swedish royals.
A toast was followed by a three-course dinner featuring Swedish ingredients that was planned since the spring.
A laureate from each category delivered a speech of gratitude near the end of the banquet.
