Sensei Next Door is reader-supported, and I want to be upfront about how this site makes money.
Some of the links on this site are affiliate links. If you click one of those links and buy something or sign up for a service, I may earn a commission from the company — at no extra cost to you. The price you pay is exactly the same as if you had gone to the company’s site directly.
Programs this site participates in (or may participate in) include affiliate programs offered by Japanese learning services, snack subscription companies, and travel SIM providers, sometimes through affiliate networks such as Impact.
What this does not change
- A product does not rank higher because it pays a commission.
- I include products and services I earn nothing from when they are genuinely a good option for the reader.
- If a comparison is based on official product information rather than my own hands-on use, the article says so.
Affiliate income is what keeps this site running without charging readers. If you’d rather not use an affiliate link, you can always go to the company’s website directly — no hard feelings.
