The DCM app makes sense when your Sunday project ends at a DCM Kama, Daiki, Homac, Sanwa, Kuroganeya, or Keyo. VOIPO points build up, the electronic-money MEEMO covers checkout, and the how-to columns are surprisingly deep. Step off DCM’s map and the value drops to nothing, the point balance can’t leave the app, and the app’s flyer feed only shows DCM branches. If a Cainz opens closer, or a Kohnan runs a project sale you can’t miss, the loyalty math starts working against you.
Below are seven DCM app alternatives that cover other Japanese home centers and the cross-chain loyalty apps that catch what DCM’s ecosystem misses.

Why people leave the DCM app
The complaints from home-improvement forums fall along three lines.
The store network is narrow. DCM’s holding company runs Kama, Daiki, Homac, Sanwa, Kuroganeya, Keyo, and Hodaka. If your local home center is Cainz, Kohnan, Nafco, or Komeri, the DCM app is dead weight.
VOIPO points don’t leave the app. DCM’s electronic-money MEEMO is chain-scoped. Points can be redeemed for merchandise or converted into MEEMO at checkout, but they can’t cross into a rival wallet or a general loyalty program.
Flyer alerts stop at the DCM boundary. The “info on local deals” feed only surfaces DCM branches. A cross-chain shopper still has to open Cainz or Kohnan to catch competing weekly campaigns.
The alternatives
Cainz: Best overall home-center alternative
Cainz runs Japan’s most design-conscious home center chain, and the app carries that identity, Cainz Style catalog browsing, buy-online-pickup-in-store, product-inventory checks by branch, and a coupon feed tied to the Cainz Card. Earn is 0.5% base on the Cainz Card, with campaign multipliers around DIY seasons.
Where it falls short: The Cainz Card is required for most earn, non-cardholders get the flyer feed and store search but not the point flow. The app leans on notifications heavily during peak seasons.
Pricing:
- Free: full app, flyer feed, store map, product search
- Paid: no paid tier; Cainz Card is free but issued by Cainz Financial
- vs DCM: sharper product catalog, comparable earn rate
Migrating from DCM: No transfer. Register a Cainz membership; the DCM VOIPO balance stays where it is until spent.
Bottom line: The default swap when Cainz is your nearest home center.
Kohnan: Best for west and central Japan DIY regulars
Kohnan runs 400-plus home centers concentrated in Kansai and Chubu, and the app is coupon-first rather than points-first. Membership is free, discounts push automatically once you register, and the flyer feed tracks weekly deals plus larger project sales (season openers, month-end clearance).
Where it falls short: No structured point ladder, the value comes from redeeming coupons on the day they appear. Miss the notification and the discount is gone.
Pricing:
- Free: full app, coupons, flyer feed
- Paid: no paid tier
- vs DCM: coupon-driven earn, no permanent point balance
Migrating from DCM: No transfer. Kohnan’s membership ID is separate.
Bottom line: Best pick when Kohnan runs your local DIY campaigns.
Nafco: Best for Kyushu and Chugoku shoppers
Nafco operates 350-plus stores across western Japan, and the app hosts the Nadepo Card membership plus Nadepo Points earn on purchases. Uniquely among the Japanese home-center apps, Nafco threads furniture and DIY into a single store map, furniture-heavy stores show a different catalog than DIY-only branches.
Where it falls short: Limited reach outside western Japan. The dual furniture-plus-DIY inventory can be confusing when checking online stock.
Pricing:
- Free: full app, Nadepo Points, coupons, campaign information
- Paid: no paid tier
- vs DCM: comparable earn, wider furniture selection
Migrating from DCM: No transfer. Nadepo Points are chain-only.
Bottom line: Nafco is the clean pick if furniture and DIY sit in the same basket.
Komeri: Best for rural and agricultural buyers
Komeri runs Japan’s largest home-center count at more than 1,200 branches, and the network reaches deep into rural prefectures no other chain covers. The app earns points at 1 per 100 yen, and the catalog leans hard into livestock feed, farm equipment, and outdoor-work supplies alongside standard DIY.
Where it falls short: UI reflects the target audience, dense listings, less polished than Cainz. Feature updates ship slowly.
Pricing:
- Free: full app, point earn, campaign info
- Paid: no paid tier
- vs DCM: broader rural reach, comparable earn rate
Migrating from DCM: No transfer. Register a new Komeri Card in-app.
Bottom line: Komeri is the only home-center app worth carrying if you shop for a farm, kennel, or garden as well as a house.
V-Point: Best cross-chain loyalty for DIY runs
V-Point (the T-Point successor, since 2024 the SMBC merger) earns at ENEOS, FamilyMart, Welcia, and TSUTAYA, the exact stops a DIY project usually pairs with (fuel for the truck, coffee on the way, painkillers for after). It doesn’t earn at any home center directly, but stacking it beside a chain-loyalty app catches value the home-center program can’t.
Where it falls short: Zero earn at home centers themselves. Legacy T-Point users still hit occasional rebrand friction.
Pricing:
- Free: full app, barcode earn, partner coupons
- Paid: no paid tier; V-Point Card is free but issued via SMBC
- vs DCM: complementary, different partner network with no overlap
Migrating from DCM: No transfer. T-Point balances rolled forward to V-Point after the merger.
Bottom line: Stack V-Point on your home-center run for the fuel and coffee at the same trip.
Rakuten Point Club: Best for online DIY orders
Rakuten Point Club is the counter-argument to any physical home-center card if your project runs through Rakuten Ichiba. Base earn is 1% on Rakuten purchases, campaign multipliers push it to 15x during Super Sale weeks, and the online catalog covers DIY, garden, and household from thousands of sellers.
Where it falls short: Nothing at physical DCM, Cainz, or Kohnan stores. Shipping windows are longer than home-center same-day pickup.
Pricing:
- Free: full app, Rakuten Points earn and burn
- Paid: no paid tier
- vs DCM: online-only, higher earn ceiling on Rakuten purchases
Migrating from DCM: No transfer. Rakuten and DCM operate different ecosystems.
Bottom line: Best swap when the project waits a day for shipping and price beats convenience.
WAON: Best for Aeon-adjacent shoppers
WAON is the AEON Group’s IC prepaid wallet, useful because home-improvement runs often chain with a grocery stop at MaxValu, Aeon Mall, or Ministop. Earn is 0.5% base, 1% on Aeon Day (the 20th and 30th). It doesn’t earn at home centers directly, but tapping the same wallet at the grocery stop that follows the DIY run does.
Where it falls short: No earn at home centers. Coupons focus on Aeon brands.
Pricing:
- Free: full app, IC charge and burn
- Paid: no paid tier
- vs DCM: complementary, WAON earns where the DIY app can’t
Migrating from DCM: No transfer. Physical WAON cards migrate via the “Move to phone” flow.
Bottom line: Pair WAON with a chain-specific home-center app to catch earn on the whole trip, not just the DIY leg.
How to choose
Pick Cainz if a Cainz branch is closer than your DCM store, the catalog and same-day pickup make it the strongest standalone alternative.
Pick Kohnan, Nafco, or Komeri based on region. Kohnan wins in Kansai, Nafco in Kyushu and Chugoku, Komeri in rural and agricultural areas.
Stack V-Point, Rakuten Point Club, or WAON on top of your primary home-center app. They earn at partner networks the home-center app can’t reach.
Stay on DCM if a DCM, Kama, Daiki, Homac, Sanwa, Kuroganeya, or Keyo is your default and you already use MEEMO at checkout. The VOIPO earn and how-to catalog are strong inside DCM’s own network.
FAQ
Which Japanese home-center app is best overall?
Cainz for catalog polish and same-day pickup, Kohnan for west-Japan coupon depth, Nafco for combined furniture and DIY, Komeri for rural reach. None of them earns cross-chain, so pick by proximity.
Can I transfer VOIPO points to Cainz or Kohnan?
No. VOIPO points redeem inside DCM’s store network only. There is no direct transfer path between home-center loyalty programs.
Is there a home-center app that works everywhere in Japan?
No single chain covers all of Japan. The closest to universal is stacking a nearby chain app (DCM, Cainz, Kohnan, Nafco, or Komeri) with a cross-chain loyalty app like V-Point, Rakuten Point Club, or WAON.
What is the cheapest DIY loyalty app?
All the chain-loyalty apps listed here are free with no paid tier. Cost per DIY project depends on which chain’s shelf prices are lowest in your region, not on the app.
Does Cainz accept PayPay?
Cainz supports major cashless payment options at checkout, including QR wallets like PayPay in most stores. The Cainz Card and its associated app-based earn work in parallel.
