What's New!

  • February 24th, 2026:
    Medaka Protocols by AI (NotebookLM-based) is coming!
    We have created an AI-based protocol collection that allows you to search existing medaka protocols using NotebookLM and ask your questions in chat format.
    The system supports multiple languages, including English and Japanese.
    If you have any protocols you created independently, please send them to naruse@nibb.ac.jp and we will include them in our source.

    A new Medaka histology atlas (Embryos and Adults) has just been released from Spain. Prof.
    Miguel González-Doncel’s group has launched a website dedicated to medaka development and adult tissue histology.
    This is the result of over 10 years of effort (https://www.inia.es/serviciosyrecursos/recursosdocumentales/medaka/Paginas/Credits.aspx ).
    Please enjoy the beautiful histology.
  • December 16th, 2025:
    We created a map showing the locations where wild medaka can be collected (https://shigen.nig.ac.jp/medaka/map/medaka_interactive_map_en.html).

    This interactive map shows 164 collection points for wild medaka. These points are categorised into groups such as Northern Japan, Southern Japan, Hybrids, Eastern Korea, China–West Korea and an uncategorised group. The map covers locations in Japan, Korea, China and Taiwan, providing details on latitude and longitude ranges. You can interact with the map by tapping or clicking on the markers to view additional information.
