Complete Offers and Surveys on Freecash (￥730 to ￥3,640 per Task)
Freecash is one of the highest-paying rewards platforms available. You earn real money or gift cards by completing tasks like playing games, trying apps, answering surveys, and testing products. Over users have joined, and it holds a rating from over reviews on Trustpilot.
The fastest way to reach ￥7,280 is through gaming offers. These are sponsored challenges inside popular mobile games, such as reaching level 30 in 14 days, and they pay more than surveys.
How to get started:
- Sign up for free at Freecash.com
- Browse available offers, filtered by payout size or time required
- Complete your chosen offer and cash out via PayPal, crypto, or gift card
A single completed offer can pay anywhere from ￥730 to ￥7,280 depending on the game and the milestone. If gaming isn't your preference, surveys are a practical alternative. They take a few minutes each and add up over time with consistent effort.
Pick offers that match your schedule and stick with them. How much you earn depends on the offers you complete.
Note: You are not guaranteed ￥7,280 a week; however, it is possible depending on how often you are using the app.
Walk Dogs (￥5,830 to ￥21,840 a Week)
Dog walking is one of the most underrated side hustles available. A standard 30-minute walk pays ￥2,180 to ￥3,640, which means two or three walks gets you to ￥7,280.
Apps like Rover and Wag make it easy to find clients in your area. Set up a profile, list your rates, and let pet owners come to you. Once you have a few regulars, bookings become predictable.
The barrier to entry is low. You don't need a car, a certificate, or any startup cost — just reliability and a willingness to work with dogs, which is all most pet owners are looking for.
Start slightly below the local average rate to land your first few clients and collect reviews. Once you have five or more, bring your rates up to market. Bookings tend to follow quickly.
Sell Things You Own (￥4,370 to ￥29,130 a Week)
Most people have ￥29,130 to ￥72,820 worth of unused items at home. Old electronics, brand-name clothing, workout gear, and video games all have buyers.
Platforms like Facebook Marketplace, eBay, and Depop for clothes make it fast and free to list items. A photo, a short description, and a fair price is usually enough. Many sellers clear ￥5,830 to ￥14,560 in their first weekend from a single sweep of their home.
Once you've worked through your own inventory, you can extend the approach by sourcing items cheaply at thrift stores or garage sales and reselling at a markup. This method, called flipping, is a practical way to push well past ￥7,280 a week and potentially earn an extra $1,000 a month.
Categories that sell fastest: smartphones, gaming consoles, name-brand shoes, tools, and baby gear. These move quickly and hold value well.
Deliver Food During Peak Hours (￥7,280 to ￥21,840 a Week)
Food delivery through DoorDash, Instacart, or similar delivery platforms is one of the more flexible ways to earn extra income. You choose when you work, with no fixed schedule.
Timing matters for hitting ￥7,280 without spending your entire weekend. Dinner hours (5 to 9 PM) and weekend lunches see the highest demand, meaning higher base pay, more orders, and better tips. Two or three hours during those windows can net ￥4,370 to ￥8,740.
Most platforms let you cash out daily. You'll need a car (or in some cities, a bike or scooter), a valid license, and a smartphone. Sign-up takes about 15 minutes and most drivers are on the road within a few days.
Tutor Students Online (￥4,370 to ￥17,480 per Week)
If you're skilled in any subject — math, science, English, a second language, music theory — there's likely a student willing to pay for help. Online tutoring pays between ￥2,180 and ￥7,280 per hour depending on the subject and level, so one or two sessions is often enough to hit a weekly target.
Platforms like Wyzant, Tutor.com, and Preply connect you directly with students. You set your own availability and rate, work from wherever you like, and sessions typically run 45 to 60 minutes.
Demand is especially high during exam periods (March to May and October to December), but parents and students look for support year-round. Most platforms require a subject-knowledge check and a solid rating — no teaching degree needed.
Get Paid to Test Websites and Apps (￥4,370 to ￥14,560 per Week)
Companies pay real users to click through their websites and apps before launch and provide feedback. On platforms like UserTesting and Freecash, a typical 20-minute test pays ￥1,460 to ￥8,740.
Tests are assigned based on your demographic profile, so a complete profile means more opportunities. New testers often receive their first test within 24 to 48 hours of signing up.
Donate Plasma (￥7,280 to ￥14,560 per Week)
Plasma donation is one of the fastest ways to make ￥7,280 in a single sitting. First-time donors at most centers earn a boosted rate, often ￥7,280 to ￥14,560 for the first visit, and repeat donors earn ￥4,370 to ￥7,280 per session. Most people can donate up to twice a week.
The process takes around 60 to 90 minutes, most of which you spend sitting in a chair. You'll need to pass a basic health screening, but the requirements are straightforward if you're generally healthy.
Search for BioLife, CSL Plasma, or Grifols centers near you. Most have online booking and some offer sign-up bonuses that increase your first-month earnings.
Run Errands via TaskRabbit (￥5,830 to ￥17,480 per Week)
TaskRabbit connects you with people who need help with everyday tasks: assembling flat-pack furniture, hanging shelves, helping someone move boxes, running errands, or doing basic cleaning. You set your own hourly rate, most Taskers charge ￥3,640 to ￥6,550 per hour, and choose only the jobs that fit your schedule.
The variety keeps it from feeling repetitive. Tasks range from setting up a TV to doing a grocery run for a busy parent. Pay is typically same-day.
To get started, create a profile, choose your task categories, and pass a background check. Many Taskers land their first job within a week of signing up.
Sell Unused Gift Cards (￥2,910 to ￥11,650 per Week)
Most people have at least one forgotten gift card in a drawer; a restaurant you never visit, a store you don't use, a streaming service you already have. Those cards are money you haven't collected yet.
Sites like Raise and CardCash let you sell unwanted gift cards online in minutes. You won't get face value, typically 70 to 92% depending on the brand, but it's money you'd otherwise leave unclaimed and it hits your account fast.
It's not a repeatable weekly earner on its own, but paired with other methods, it's an easy ￥2,910 to ￥7,280 you can collect in an afternoon.
Offer Yard Work and Odd Jobs on Nextdoor (￥5,830 to ￥21,840)
Local neighborhood apps like Nextdoor are full of people who need simple tasks done: mowing the lawn, raking leaves, cleaning out a garage, and pressure washing a driveway. These jobs pay ￥3,640 to ￥10,920 each, and you can usually book them within 24 hours of posting.
You don't need equipment to start. Many homeowners have their own tools and just need the labor. A good reputation in a neighborhood brings steady work without advertising.
Post a simple offer in your local Nextdoor group with your name, what you're offering, your rate, and your availability. Most people book based on proximity and trust, so keep it short and direct.
