Teaching kanji and kana micro-skills online can be a challenge. Whiteboard.fi allows you to see each student's whiteboard. The free version allows you to create a session that will last a few hours. The paid version will allow you to create worksheets that each student will see on their whiteboard. For online classes that have access to a mobile device in addition to a laptop, this is an excellent tool. This tool can be used in the classroom as well and allows the instructor to view all students at the same time.
Group learning becomes dynamic when all participate with the same shared document. Hypothesis allows students to mark and post questions either synchronously or asynchronously. It can be used during an online class session or used for homework discussions. I use this with Google Docs that students can only view. As a group they can mark the document and pose questions without changing my original item. This app only works with text documents.
My favorite tool for online synchronous classes and student created content. Jamboard allows up to 20 different slides. I prefer to set the background image as a worksheet or image from a graded reader for novice students to annotate, mark up, and write notes. I create one document for each project rather than each day; this allows work from previous sessions to carry forward.
Bitmoji This may seem childish at the college level, but my bitmoji is set to Japanese. Also, Japanese culture, regardless of age, loves to use images as well as text. In fact the word moji is Japanese. Emoji = Picture word. So this is a very Japanese thing to incorporate.
Most beginning students of Japanese need to learn to read, image searches with pinterest provide more robust results than an image search on google or other web browser.
