Hey,
I'm not learning Jap nor have I learned it. However I am learning Indo, and I will share some tips when learning vocab

[It's probs harder memorising Jap words tho

]
- I complete vocab games - such as fill in the gap, cross words etc < I found this really useful (there should be books like this!)
- I put vocab in sentences , sentences that are relatable
- I try to use vocab everyday - make random sentences or even think of vocab while replying to people in English < haha a bit weird I know ...but constant retrieval is the key!
- In fact you should try and
speak in Jap constantly with new vocab. - Even if it's talking to yourself!
- Cue cards , ask others to test you
- Watch dramas in Jap or with Jap subs
- READ... I cannot stress this enough... vocab will really start to sink in when you come across it multiple times! Especially the common and essential vocab ... read newspaper articles in Jap . If that's not your thing, read cartoon, dialogue, interviews, stories
- ^ the aforementioned dot point...is what I truly believe will help you. Constant exposure will plant vocab in your brain
- Probably look for material e.g reading material, listening material that's organised by themes. E.g I read articles or excerpts of info related to a topic such as Environment or Indonesian Lifestyel or Indonesian Food etc... and in a sense, vocab should be 'grouped' ...and once again , specific vocabwill reappear in similiar texts < so constant exposure and retrieval
That's all

Good luck, hopefully this helped to an extent
