There are also these guys: https://www.simcardgeek.com/product-category/japan-sim-cards-for-tourists/

Again prices are not bad for unlimited 4G data cards: - 8 Days - ¥4000 - 16 Days - ¥6000 - 31 Days - ¥7500

However again no info on any data allowances or throtling other than this response to a 1 star rating complaining about slow internet speed:

"Our SIMs offer 4G LTE data where available. Speeds may sometimes be restricted due to network fair usage policies or high traffic. We’re very sorry to hear you have experienced problems using your SIM. Would you please confirm what kind of device (smartphone/tablet/MiFi, etc.) and the make and model of the device you are using (eg iPhone 6)? We’ll be glad to try and investigate the issue for you. If we are unable to fix the problem, we’ll be glad to replace or refund your service."
