If you're looking for a podcast that offers authentic, everyday Japanese, we recommend you check out Let's Learn Japanese From Small Talk! The podcast is hosted by two native speakers of Japanese, and they cover a wide range of interesting topics about modern life in Japan. We covered this podcast in another Japanese Learning Resources article a year ago, but it has really come into its own since then!
One of my favorite things about the podcast is how well the hosts provide vocabulary support for listeners. Instead of simplifying their Japanese, they provide English translations of difficult words, or explain what words mean using other words in Japanese. At the end of each episode, one of the hosts slowly pronounces each word covered in the episode, leaving enough time in between for listeners to pronounce the words after her. Vocabulary lists for each episode are posted on the podcast blog, which makes this a really great study tool!
I would recommend this podcast to upper-intermediate and advanced learners, however a more beginner level learner could try studying the vocabulary list before listening to the podcast to see if it is more accessible that way. In any case, if you're in need of an enjoyable and informative Japanese podcast, give it a shot!
