Before his return from Japan after his successful research stay at Kyoto University, Alex Vano-Vinuales visited Rikkyo University in Tokyo, invited by former GRIT postdoc Masashi Kimura. After some sightseeing in Nikko in the morning, Alex delivered a successful seminar on the current status on free hyperboloidal numerical evolutions to the group at Rikkyo University, followed by a very interesting discussion and dinner at one of Masashi's favourite restaurants.
