“I’m working my way through Japan’s 100 Fine Castles, but Shinkansen fares are straining the family budget…”
“I want to visit faraway castles, but losing tens of thousands of yen on travel alone really hurts.”
For castle fans facing that dilemma, “JRE BANK” has become essential equipment.
Especially for managers and parents, a system that gives you up to 10 Shinkansen trips a year at 40% off just for keeping your assets in the bank delivers a far higher ROI than chasing interest rates. It’s a true “strategic investment.”
In this article, I, the author of Shirolog, will walk you through how to use JRE BANK to conquer more castles.
1. Spec Sheet: The “Provisions” Your Balance Earns You

2. Strategy Guide: The “Three Conditions” for Maximizing Your Perks
To unlock the full number of 40%-off coupons and “Dokokani Viewn!” discounts, my approach is to run the following three conditions as a set.
| Condition | Action | Perks unlocked |
| ① Account balance | ¥500,000 or more — hold the line | Eligible for all perks (this alone gets you the Green Car tickets) |
| ② Card payments | Pay with a View Card at least once a month | “Dokokani Viewn!” discount — unlock the maximum |
| ③ Salary deposit | Set it as your salary deposit account | Discount coupon (40% off) — unlock the maximum |
“Deposit ¥3 million and set up salary deposit and card payments.” With just this one-time setup, your rights to 40%-off Shinkansen tickets and free Green Car rides will arrive automatically on a regular basis. Just be sure to manage your balance carefully on the assessment dates (such as June 25 and December 25).
3. The Castle Fan’s “Three-Layer Strategy”: Putting Your Perks to Work
The secret to a smart castle campaign is choosing which perk to use based on the distance and purpose of the trip.
① [Long trips / overnight] Boost your Shinkansen savings with the 40%-off coupon
- Targets: Hirosaki, Morioka, Aizu-Wakamatsu, and Sendai castles (faraway castles in the JR East area)
- Tactic: A round trip between Tokyo and Hirosaki saves you about ¥14,000.
- Benefit: Spend the savings on the finest local sake and specialty food as a victory toast after the siege. A powerful ally for full-scale castle trips with an overnight stay.
② [Nearby / day trips] Save your energy with the free Green Car ticket
- Targets: Odawara, Utsunomiya, and Sakura castles (Greater Tokyo area)
- Tactic: Ride the Green Car on local trains for free.
- Benefit: Castle touring means a lot of walking. Save your energy on the way there, and relax on the way home while sorting your photos and pamphlets. This upgrade in travel quality makes a day trip the best it can be.
③ [Leave it to luck / exploration] Head to unknown castles with the “Dokokani Viewn!” discount
- Targets: 100 Fine Castles and Continued 100 Fine Castles that weren’t on your list
- Tactic: Book a round-trip Shinkansen for just 4,000 points (normally 6,000 points).
- Benefit: Letting fate decide your destination pushes your stamp rally forward at an unexpected pace. (“Dokokani Viewn!” is a JR East service that picks a random destination for you.)
4. Which Type Are You? Choosing Your View Card
Two strategies for the “second bailey” gear that keeps and maximizes your perks.
- [Maximize points] Gold card:For “offensive” castle fans aiming for 10% back on Mobile Suica top-ups, who want to use their points to fire off one “Dokokani Viewn!” trip after another. Lounge access lifts your mood before a long trip, too.
- [Maintain perks] Standard card:A “defensive” plan: hold it for the ¥524 annual fee purely to meet the payment condition for the 40%-off coupons and “Viewn” discount.
Summary: Whoever Controls Travel Controls the Castles
Just by keeping money in the bank, the Shinkansen gets 40% cheaper, the Green Car becomes free, and 4,000 points can send you to a castle you’ve never seen. For castle fans, JRE BANK is the ultimate piece of equipment.
Optimize your “siege costs” — transportation — and invest in more great castles and deeper history experiences!
